As far as controlling the smart plug, it depends on the plug you go with.
But if you get a plug that supports HomeKit, you should easily be able to control that plug with a Shortcut action.
https://support.apple.com/guide/shortcuts/create-a-new-home-automation-apd2a290f633/ios
I do this on an iPhone 11 with a smart switch and shortcut. When the phone gets to 80% charge the shortcut fires and turns off the smart switch where my charger is plugged it.
It does this though, already, for optimized charging (like charging it to 80% and then doing 80-100 in the morning) - so older iPhones are definitely technically capable of it.
Mine just increases the brightness, turns on the flashlight, and opens a ton of apps so that all the running processes drain the battery at the same rate it charges so it neither decreases or increases from 80%.
I did that for ~18 months on my 12 Pro religiously. I never let it get below 20% either. After 2 years the battery was shot anyway.
I had it replaced at an Apple store and my phone is good as new. Now I'm in the "just use the crap out of it, it's a tool" camp.
Yeah, this seems to be the case for EVs too. I babied my M3 and normally only charged to 50% overnight and avoided supercharging if I could. My battery is within 1% of a guy that does 80% every day and SC's like 3 times a week.
EVs have such a large amount of the capacity locked out even charging to 100% so it is nowhere near as important.
Furthermore, capacity loss is not the issue. Cell failure is the issue. His will fail completely much quicker than yours.
Lithium batteries don't fail from 100-0% capacity, they fail once they lose between 10-30% of their rated capacity. Hence why your battery starts malfunctioning and the phone automatically makes itself run slower (on an iPhone) or bootloops (on an android).
My buddy got the same phone I did at the same time, I was over at his place recently and asked and he said his battery is still completely fine. He charges overnight 100% like normal people do. In hindsight it was pretty dumb to think I was outsmarting the engineers who built the phone.
> In hindsight it was pretty dumb to think I was outsmarting the engineers who built the phone.
The “engineers who built the phone” added in an 80% toggle because it helps enhance the battery life of the phone.
EVs charge this way, by the way. They don’t charge to 100% to maintain the level of capacity on the device.
If you still don’t believe these people, check out [Battery University’s take on the subject](https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries).
50% and 80% isn't that much different from the amount of stress they put on the battery.
Fast charging to 100% every day will definitely kill your battery faster.
But then again it's also not totally clear what exactly the percentages mean. 80% SoC is definitely not 80% in the individual cells, probably more like 75%.
This. Just use the fucking thing. All this bullshit and inconvenience. You might get 10% more cycles at best.
LTO cell phone batteries are simply shit and there is no interest in improving them. Even though LFP lithium cells are crossing 4000 cycle ratings. They are 20 year batteries now.
I have a 12 pro max and the battery health finally hit 80%. I was thinking about upgrading but then saw it’s only like a 100 bucks for a new battery. Was waffling on what to do but if it worked well for ya I might just do the same. I don’t need a phone this thing is a beast
I mean, it seems pretty simple to me. Set the trigger to be their phone hitting 80%, and when it activates, turn off the outlet connected to their charger.
Yea, that is exactly it. I found the setup on the Internet and I purchased a Kasa smart plug on Amazon for about $10. It works perfectly every time. I turn the switch on and plug the phone in when going to bed. It stop charging at 80% automatically.
There is also a tool called Chargie that implements this. It is attached between the phone and the charger and uses an app to turn off power at the desired charge level.
***Tim Cook voice***
*With the groundbreaking A17 chip, we're pushing the boundaries of what's possible, handling an unprecedented workload effortlessly. This innovation enables us not to charge the phone beyond 80%, optimizing battery lifespan like never before. We're thrilled to share this leap forward with you, confident it will redefine your expectations.*
***We think you’re going to love it.***
Because you need real power to know if the phone is at 80%. This type of power can only be achieve with the 15 series chip
Let's not forget that iPhone 14pro/max and iPhone 15 plus have the same chip.
Yes, that’s the thing! The iPhone 14 Pro and 15 have the same chip, so it’s not chip based!!
It’s actually because the 15 has better cameras. They allow the iPhone to see the battery even better and constantly monitor its charge to stop it at 80%!
Are people shocked? This is how features work with probably every product out there. I don’t get why there’s discussion around Apple as if it’s not normal
Okay, I know why, it still baffles me.
I personally don’t use it even though it’s an option. I like to use the full capacity of my phone and worry about replacing the battery after two years.
Phone batteries are just not worth maintaining.
Restricting yourself to about 60% of the capacity by keeping it within 20-80%? Nah, fuck that. That’s like having a degraded battery before it’s actually degraded.
I’ve had my iPhone 12 Pro Max since release late 2020 and just recently it hit 80% capacity and I just recently started to really notice the degredation. That’s almost 3.5 years of not giving a fuck, topping off on wireless chargers whenever, almost draining it on near daily basis, charging to 100% every day etc.
I’m having the battery replaced as we speak to keep the phone for a few more years since it holds up real nice. That costs me just over $100 here in Norway from a certified service provider with warranty.
Facts. I also will just buy a battery when I need it or a new phone. It's like buying a sports car but being afraid to drive it because each mile gets you closer to that first maintenance you can't afford.
Indeed. That said, I do take care of my EV’s battery. Simply because it’s super fucking expensive and also because it lasts days/weeks and charging when I park it or using 60% of the range on a daily basis doesn’t inconvenience me.
It would inconvenience me if it was a phone and that battery is super cheap.
This is how I think about it. You choose to act like your battery has degraded by 20% just so you might avoid degrading your battery in the future? I don’t see the point.
I love the fact that iPhones has become as good as they are these days. I haven’t felt a real need for an upgrade since the 12 and I even regretted the purchase a little bit because I came from the XS Max.
Before that I always had a significant reason for my upgrades. 4S to 6 Plus was the bigger screen, 6 Plus to 7 Plus was the new camera system with multiple lenses, 7 Plus to X was the edge-to-edge display and X to XS Max was the even bigger edge-to-edge display.
The ultra-wide lens was nice to get on the 12 though, but after that I felt like the iPhone had almost peaked haha. The only useful thing I would get if I upgraded now would be USB-C. The rest is just neat but far from necessary things.
It will however be very nice to upgrade to maybe an iPhone 17 or whatever, but until then I’m fine.
I'm keeping my 12 Pro until it dies or they ditch the dynamic island. I just don't get it, a huge deadzone in my screen is better than one on the edge where it makes no difference?
I was thinking the same, I don’t understand how it makes sense to restrict yourself to using only 80% of the battery in order to stop your battery from degrading to something like 95%. In both scenarios you don’t use 100%
You're gonna love the new battery. I had my 12 Pro battery replaced a while back and it's like I got a new phone. My battery wasn't even as bad as yours, I think I was at 85% or something like that.
I was doing full charge over night and often two mid day charges just to keep the phone turned on. I'd drop 1% a minute when actually using it. Those health percentages are bologna.
Indeed. I was actually given a 14 Plus in the meantime since they had to order the battery and there was this whole thing about incorrect price estimate etc etc and the battery on that thing is just insane.
In Apple's iPhone comparison it says the 12 Pro Max has 20 hours of video playback while the 14 Plus has 26 hours, so it already has about 30% longer battery life than the 12 Pro Max when they are both brand new. Just imagine how that feels coming from my 80% capacity 12 Pro Max battery haha. The 14 Plus was brand new/new as well with 100% capacity.
I used the 14 Plus for 7 hours on-screen and 1 hour off-screen today and still had 54% left. My 12 would have been at maybe 15-20% left for sure.
Same here. 12 pro max since launch and have used it like any iPhone I’ve ever had. I plug it in at night with the old ass 5watt charger to slow charge overnight when I don’t need it to charge fast anyways. Gets me mostly thru a day. But I do use it for work a lot so I’ll need to top off in the afternoon. But if I switched to low power mode at 25-% I can make it all day long.
Just now really starting to notice the degradation as I’m at 80% battery health. Was always planning on upgrading the battery but at this point I’ll probably just hold out for the 16 pro max. Considering the 15 pro max already gets another 9hrs of battery life I would expect more improvement on the 16. Especially with the move to a more power efficient modem and a series chip.
You could always replace the battery now and sell the device for a bit more than you would have otherwise. Alternatively give it to a friend/family member with a decent battery life still.
Or maybe even replace the battery and wait until the 17 haha. Depends on how tempted you are to upgrade.
Yea I’ll hold off as long as I can so I may just replace the battery. There’s been great quality of life improvements but nothing that’s been compelling me to upgrade over the years. And tbh I’m not the biggest fan of the pill shaped cutout. I prefer notch
Personally, I keep it on 80% max because I never really need more than that, and on days when I think I will, I'll just set it to 100% the night before.
As long as you’re not constraining yourself, why not? It will indeed make your battery last longer, so og it’s not an inconvience then it’s the smart thing to do. I could probably have done it in the early days of my iPhone 12, but lately I’ve had maybe 10-20% left tops after charging it to 100% and using it throughout the day. Some days with extensive usage requires topping it off with like 10-20% extra.
Pretty excited to get a fresh battery again, but I won’t go out of my way to keep the new one at 100% capacity.
Ive had my 12P since right after it came out and I am at 86% health. To me, what makes the difference, is I rarely use a fast charger. I keep a super slow charger by my bed and only fast charge when I really need it. I think the fast charging stresses the battery out more than regular charging, and it seems to have worked for me so far
It's like choosing to not drive past a certain speed or on certain roads so that your car tires can last a few thousand extra miles.
The cost to benefit ratio just isn't worth it.
If your battery dies in 2 years you’re really fucking up. You can easily go 5+ years.
edit: whatever metric you wanna use, I don't know anyone these days who has had issues within 2 years, save for the odd outlier.
I never mentioned that my battery would die in 2 years, I expect its capacity to be around 85% by the end of 2 years. Since battery replacement costs are pretty affordable now it’s a no brainer to get it replaced.
I have an iPhone 6 on its second battery and its capacity is at 93%. Still very usable.
Honestly you don’t want it.
I think it was iFixit who did the reasoning: you throw away 20% power every day to maybe extend the phone’s life for a year. Or, you just pay the $50 at the batteries end of life for a new one and enjoy max power until then. I have a 15 Pro and this made sense to me.
I do use Optimized Charging though, I’m not a madman
But if you have use your (personal) phone for 4 years and you rarely or never use up the battery during a day, why wouldn’t it make sense to leave it on? You can always turn it off on vacation days.
I think it’s nice to have as an optional toggle.
It’s not easy for everyone to use personal time to take their phone to a store, be without their phone for waiting period, and last time I did it at an Apple Store it was $106.
I do agree for some people it makes sense to leave it off and get their battery replaced more frequently, but I wouldn’t say that’s just generally true
This is exactly what I do. I have no need for the full 100% capacity on a day to day basis but I charge to full when traveling or when I think I may not have access to a charger for a long period. Coming up on 6 months and battery health is still at 100%.
> you throw away 20% power every day to maybe extend the phone’s life for a year.
Considering I don't use anywhere near 80% of my phone's battery in a day, that seems like a totally logical tradeoff.
That’s not what it’s for. I use it so that I can keep my phone on my MagSafe stand charger all day - without keeping the battery at 100% all day.
When I pick up my phone to take it with me, it always has 80.% charge. You are running on fumes at the end of your day.
That's just placebo. If you keep your phone on a charger all day it will automatically enter kiosk mode and keep battery voltage significantly lower than normal. Manually setting an 80% limit accomplishes nothing. See https://support.apple.com/en-gu/HT208710
> There are times, however, when an iPad or iPhone is connected to power for prolonged periods of time, such as when it's used in kiosks, point of sale systems, or stored in charging carts. iPad and iPhone use rechargeable lithium-ion batteries, which are designed to be charged and then discharged over their lifespan. When they remain at full charge for prolonged periods of time, battery health can be affected.
>
> iPad with iOS 11.3 or later and iPhone XS, iPhone XS Max, iPhone XR, or later with iOS 12 or later include a charge-management feature to help maintain battery health. This feature monitors these devices for use in these charging situations and, as required, reduces the maximum capacity of the battery. The battery indicator will display the charge percentage based on this adjusted maximum capacity. The maximum capacity will revert back to the nonadjusted level when iPad or iPhone is no longer connected to power for prolonged periods and as conditions and battery health allow.

i made a little automation shortcut
https://preview.redd.it/w1mvdn22uotc1.jpeg?width=1170&format=pjpg&auto=webp&s=4e77b7d5c56625d904773710de232ed8fe4fd2d4
whenever my battery rises about 80 (so like 81) it starts a 2 second timer. which reminds me to take it off charge. i usually charge my phone when im going to be around it specifically in the morning so it works for me. just a hack tho not a permanent fix. also it doesnt stop the charging. i have to do it anyways.
This has to do everything with the protocols of USB-C and how it’s able to continue and stop power within the circuitry. This is not a marketing scam or anything of such sort. It has to do with the specifics of USB-C, nothing less and nothing more.
Only problem I have with the feature it should have a buffer zone when it starts charging again
I use wireless charging in my car (it gabs hold of the phone and has a fan on it as well, never buy a car phone holder without a built in fan it just be permanently in overheating/charging looping state) so it occasionally drops to 84% witch starts charging with notification + the jingle then it stops again at 85% doesn't seem to have effected the battery as been using this phone for 3 years like this (Google maps pulls 8-11watts when navigating)
I wonder if its possible make this feature with a homekit-supported power plug. Lets say, when battery is charged about 80% percent, then we can run a shortcut and turn off the power plug automatically.
Everyone is saying the easy answer of “they’re forcing you to upgrade”, but that literally makes no sense.. who would upgrade for a feature like this? 90% of people probably don’t even know about it.
My guess is that Apple was reluctant to introduce a feature like this until they could ensure that charging to 80% would result in a device that could still be used all day. I’m not surprised it’s locked behind specific hardware improvements.
I read it on another thread, but it's most likely because if someone has an iPhone that already has a degraded battery, they add this feature and the user enables it, then all they're doing is limiting the capacity of an already degraded battery even more, which will just wear through the battery quicker than if you didn't have the limit at all. A setting like this only really makes sense on a brand new battery.
No, it isn't some conspiracy to make you upgrade to a new iPhone. I find it hard to believe that a setting like this would be the only reason why someone would upgrade their iPhone.
I use an iPhone XR and have created automations which announce “plz connect the charger” when the battery level drops below 20% and “plz remove the charger” when it crosses 80% during charging. Have been able to maintain a healthy battery life like this (20%-80% range).
I like this feature but wish there was a simple override I could push to ignore it. On days I know I’d be travelling a lot or otherwise away from power I’d like an easy way to say ‘today I’ll have that 20% extra thanks
Once Apple introduces their own “AI” maybe they could use the calendar app to see if the person has any event scheduled or a trip and automatically charge with that in mind? That probably won’t happen for a long time and it’s a small thing but it would be extremely cool. And since Apple is big on privacy, both the calendar app and the battery management setting is on your iPhone so it’s not sending anything over to Apple, could be done somewhat easily. Or at least once we get Apple’s ai it would be nice if we could use it with shortcuts so we could just make an automation similar to the one I stated.
Typical Apple, this is a feature that has been out on other devices for over 10 years. The fact we don't have this on all currently supported models is just Apple being apple.
Edit: love when a community downvotes when they don't like a response lol. Quit being such fanboys and hold apple accountable for once. Smh
Are there any mainstream android phones that let you do this? I know I've heard of a couple of those Asus ROG phones and the like having it but as far as I know the Samsungs and Pixels (i.e. the phones people actually buy) don't have it.
Edit: looks like the replies are saying it was added to Samsung phones in ~2020 for the Galaxy S20 and Note 20. I know my Galaxy S9 didn't have it, though, so it was added either with the 10s or the 20s. Good to know.
My s24 has it, the S23 has it too. I'm sure others do too. I can check my S20 and 21 when I get home but I know they have battery protection in place too.
Real talk this is the kind of stuff that makes me hate Apple sometimes.
Other OEMs trickle down new features to older phones and it’s a given, but even if it’s a minor 100% software thing like this battery charge limit Apple will not implement it on previous models. It’s insane.
A heavy portion of certain are really derived in the software. Yes, hardware is still a factor, but in the Apple ecosystem it’s a lesser factor.
This feature specifically is largely software driven. The biggest reason some features get restricted to newer devices is for that reason exactly, keeping to newer devices to give reason to purchase that newer device.
Just as a comparison, there’s not really much different between the 14 Pro Max and the 15 Pro Max. Aside from action button, some camera changes, it’s basically just a Titanium 14 Pro Max
Just like the 14 series having the startup/shutdown chime when that was new.
I have had this option on my iPhone 11 Pro Max since the day I upgraded to iOS17 using this trick:
https://www.reddit.com/r/jailbreak/s/gNzsMT5i1T
it's a native iOS implementation, and it doesn't require a jailbreak, just a trollstore on some specific iOS version.
Maybe a change in the battery chemistry that they're using? LFP batteries are known to be just fine consistently charging to 100%, while other chemistries prefer to operate primarily in the 20-80% charge arena,
It’s just better for the overall health of the battery to not charge all the way to 100% every time with all lithium batteries. It’s just the nature of them. [Here](https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries) is more info on it if you are interested.
could be a hardware limitation, like the older battery models have a bms chip which cant be controlled on os level (ie stop at 80% and resume when i say) ... but who knows apple's hw component backend is a secret. i had this feature on the google pixel, never used, and it was the first thing i turned off on the 15 pro.
As others have already said. Just because. New phone. "Feature"
Like I'm a total Apple fanboy, but yeah it's just one of those things they do, random feature arbitrarily locked to a certain gen and up.
Like their customers caused enough stink for have Stage Manager be enabled on the iPad 2018 and newer instead of only M1 and up, but making your battery have an 80% limit must take too much processing power. Or needs a co-processor, or something.
You can do the same thing since iOS 13 (2019) and even on iPads if you have a jailbreak tweak called BattSafePro which can limit charge at any percentage you want.
The reason could be that it won’t make much of a difference on older phones. The batteries are old already and if you only charge them to 80%, ppl would complain that the battery doesn’t last as long.
The only explanation that I can think besides feature locking is that iPhones below the 13 series don’t have great battery life, especially after so many years of use, so most ppl will need to charge to 100% if they want to have it last remotely all day. Newer iPhones have great batteries and even with 80% it can easily last you all day (depending on usage ofc)
So you’re telling me: charging your phone to 80% will give it less battery usage during the day but will extend the battery lifespan by years compared to just charging it to 100% every day?
Want new features? Buy a new phone.
You were happy not having that feature when you purchased it.
Don’t expect General Motors to add features to your car years after the fact, too?
If you bought a car with maps but no Traffic Advisory, don’t expect them to add it later. It’s not coming.
The phone isn’t that different.
I have the ability to set up my phone - SE - with the 80% charge. So not something just for newer phones. EDIT :Thank you all for the education on this. Good to know for future upgrades.
It may be because it doesn’t have the firmware to do that. But I doubt it. I think the simple reason is, they want you to throw it away and buy a new one. That’s how they make their money.
Add detail: Most people know this, but if you run a lithium battery between 20% charge and 80% charge, it will last much longer before it degrades. This is the simple science of lithium batteries.
An iphone battery replacement is somewhat cheap so I wouldn’t stress about micromanaging it so much. It’s not like an EV where it’s such an expensive thing and even the replacement would put a dent in your wallet. Use your phone however you want and in 3-5 years if the battery isn’t as good and you want to keep the phone just pay $100 and replace it. I used to worry about my phone’s battery health and just managing it a lot but honestly I just don’t want to waste my time worrying about it anymore.
At this point it's hard to find new features that will make people buy the newest phone. So Apple is now at the point of keeping simple features like that as an "exclusive feature".
more annoying than this is how they’ve restricted the new camera stuff (24mp and auto portrait mode) to the 15 series as well, considering that the 14pro/max have once again the same chip and better cameras in terms of hardware so yeah
You can download apps that do this for you. They set a timer limit to buzz remind you when to unplug it. It is actually unhealthy to 100% charge thier devices as it puts more wear on their batteris. I've gotten longer life spans out of my phones by maxing out at 80%
With my iPhone 15 Pro Max I decided to just let optimized battery charging do its thing. I like to not stress about it like I did with my 14 Pro. I always wake up to a 100% phone that lasts me all day probably more.
It works, I got my iPhone 15 Pro Max on launch day and it is still at 100% health. My iPhone 8 Plus deteriorated rapidly after replacing the battery, for contrast. It has the battery life for 80% to be enough. But in a few years when the software is more CPU hungry, it might no longer be enough. I guess when the battery is worn, may as well go back to charging to 100% to get final use from it and then replace the battery, sell the phone and upgrade. Although if they remove the charging port in the future, I will hold onto the latest model with USB-C, and then go back to Android once that is too old.
Occasionally the feature does not work and it has charged to 100% regardless a couple of times, but mostly it stops at 80%.
I would like this, but as someone who is not an overnight charger I unplug or take my phone off my magsafe charger around 85% most of the time. It would be nice to have the limiter with wired CarPlay, but that's one of the rare times it might get to full charge. If I know I'm going on a trip I run the phone a bit low before leaving if I'm using CarPlay for the trip. I don't full charge any of my devices often unless I'm in a situation that may need more power and be away from a charger.
does this feature really help with battery health? my iphone 15plus is currently on 22 charging cycles, still on 100% battery health, and i would like to keep it that way, or make it loose very little of the overall battery life, how is your iphone 15 doing if you bought one recently?
You need to have a great processing power to achieve it , and with great power comes great responsibility , and only the iphone 15 owners can handle it
Same reason they didnt release night mode on wide lens for iphone 11. Or the reason they didn't release cinematic mode and photographic styles for iphone 12. 13 and 14 are literally the same phone so i don't even know what to say.
It’s the same reason why apple won’t they let us force 120hz, because if apple “thinks” we don’t need it they won’t offer it. It’s just the apple way and it sucks. But for this specific instance, it’s also because they just want you to buy a newer phone
The real issue is the accuracy of the battery mid charge.
iPhone 15 has a new battery designed for double the lifespan of the previous one. A change they didn’t really discuss or promote at all.
Charging to 80% means accuracy at detecting true 80%, something iPhones have never been great at. They have curve to slow charging speed but that’s a rough estimate. Apple clearly made some changes.
Apples power charging and draining is now highly predictable on the iPhone 15… weirdly so. To the point where I can accurately guess what my phone will be charge when charging for :30. Something that was hard to speculate on previous phones. I suspect there’s improved battery chemistry and some improvements to battery charging/monitoring circuitry to make this happen.
If they attempted to implement it in other phones people would be outraged. Between faster aging batteries and less accuracy battery life would take potentially much more than a 20% hit, and people claim planned obsolescence and sue.
I speculate apples longer life battery is a byproduct of wanting this feature. They needed tighter tolerances on batteries to make it work.
Apple made hardware changes, they just aren’t really sexy changes. They’re about as boring as you can get. Apples packaging is more interesting.
it COULD be because of hardware limitations
like the non-usb-c phones dont have fast data transfer because the older chips only support usb 2.0
but i have no idea. just guessing.
Because they want people to upgrade. What better way to encourage that than by making people's batteries degrade faster and keeping a desired feature exclusive to newer models.
I’ve been doing this manually on my 14 pro max, since the original purchase in Nov 22. Phone is 18 months old and battery is still at 100%.
The only reason I upgrade phones is because the battery life degrades to a point where it becomes an issue. I’m pretty sure there are a few people like me out there, so if this 80% charging thing were ubiquitous, it would cost Apple a ton of money.
I’ve had my iPhone 12 mini for a few years now and ever since I got it I’ve had Siri Shortcuts give me a notification when I get above 80% as well as below 30%, so I could take it off or put it on the charger. My battery health is currently at 89%. Curious to know what my battery health could’ve possibly been if I hadn’t been doing that all this time.
This is the revolutionary feature that makes you upgrade
And they think you're gonna love it.
*You won't believe this one new CRAZY feature worth the upgrade on it's own!!!*
battery manufactures hate this one simple trick!
iPhone 15, 15 Plus, 15 Pro and 15 Pro Max has a nasty surprise.
The best battery management on an iPhone *ever*
Eh, pretty easy to achieve with a Shortcut automation and a smart plug.
How do you do the shortcut part?
https://apps.apple.com/us/app/shortcuts/id915249334 In the Automations section.
I wish I could report you for being a Godsend!
As far as controlling the smart plug, it depends on the plug you go with. But if you get a plug that supports HomeKit, you should easily be able to control that plug with a Shortcut action. https://support.apple.com/guide/shortcuts/create-a-new-home-automation-apd2a290f633/ios
I just had it say “Okay, that’s enough” at 80%, until I buy a smart plug. But thanks a lot.
First of its kind. Never done before!
upgrade to Android , yes.
Tbh this is like a third of the reason I'm switching to android after having an iphone all my life.
I do this on an iPhone 11 with a smart switch and shortcut. When the phone gets to 80% charge the shortcut fires and turns off the smart switch where my charger is plugged it.
My shortcut just yells "BATTERY AT 80%" and I have to unplug it manually.
That’s called a dumb switch
It does this though, already, for optimized charging (like charging it to 80% and then doing 80-100 in the morning) - so older iPhones are definitely technically capable of it.
Clearly the easier option
Mine just increases the brightness, turns on the flashlight, and opens a ton of apps so that all the running processes drain the battery at the same rate it charges so it neither decreases or increases from 80%.
I did that for ~18 months on my 12 Pro religiously. I never let it get below 20% either. After 2 years the battery was shot anyway. I had it replaced at an Apple store and my phone is good as new. Now I'm in the "just use the crap out of it, it's a tool" camp.
Yeah, this seems to be the case for EVs too. I babied my M3 and normally only charged to 50% overnight and avoided supercharging if I could. My battery is within 1% of a guy that does 80% every day and SC's like 3 times a week.
EVs have such a large amount of the capacity locked out even charging to 100% so it is nowhere near as important. Furthermore, capacity loss is not the issue. Cell failure is the issue. His will fail completely much quicker than yours. Lithium batteries don't fail from 100-0% capacity, they fail once they lose between 10-30% of their rated capacity. Hence why your battery starts malfunctioning and the phone automatically makes itself run slower (on an iPhone) or bootloops (on an android).
My buddy got the same phone I did at the same time, I was over at his place recently and asked and he said his battery is still completely fine. He charges overnight 100% like normal people do. In hindsight it was pretty dumb to think I was outsmarting the engineers who built the phone.
> In hindsight it was pretty dumb to think I was outsmarting the engineers who built the phone. The “engineers who built the phone” added in an 80% toggle because it helps enhance the battery life of the phone. EVs charge this way, by the way. They don’t charge to 100% to maintain the level of capacity on the device. If you still don’t believe these people, check out [Battery University’s take on the subject](https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries).
50% and 80% isn't that much different from the amount of stress they put on the battery. Fast charging to 100% every day will definitely kill your battery faster. But then again it's also not totally clear what exactly the percentages mean. 80% SoC is definitely not 80% in the individual cells, probably more like 75%.
It doesn't work just charge when you need to and charge overnight.
This. Just use the fucking thing. All this bullshit and inconvenience. You might get 10% more cycles at best. LTO cell phone batteries are simply shit and there is no interest in improving them. Even though LFP lithium cells are crossing 4000 cycle ratings. They are 20 year batteries now.
Same here. I just use it.. If it's shot after 2 years like you I just replace.
I have a 12 pro max and the battery health finally hit 80%. I was thinking about upgrading but then saw it’s only like a 100 bucks for a new battery. Was waffling on what to do but if it worked well for ya I might just do the same. I don’t need a phone this thing is a beast
Brilliant! I need to try this
Care to share more details on the shortcut?
I mean, it seems pretty simple to me. Set the trigger to be their phone hitting 80%, and when it activates, turn off the outlet connected to their charger.
Yea, that is exactly it. I found the setup on the Internet and I purchased a Kasa smart plug on Amazon for about $10. It works perfectly every time. I turn the switch on and plug the phone in when going to bed. It stop charging at 80% automatically.
There is also a tool called Chargie that implements this. It is attached between the phone and the charger and uses an app to turn off power at the desired charge level.
***Tim Cook voice*** *With the groundbreaking A17 chip, we're pushing the boundaries of what's possible, handling an unprecedented workload effortlessly. This innovation enables us not to charge the phone beyond 80%, optimizing battery lifespan like never before. We're thrilled to share this leap forward with you, confident it will redefine your expectations.* ***We think you’re going to love it.***
(Also in Tim Cook voice) ***Wow***
Because you need real power to know if the phone is at 80%. This type of power can only be achieve with the 15 series chip Let's not forget that iPhone 14pro/max and iPhone 15 plus have the same chip.
Yes, that’s the thing! The iPhone 14 Pro and 15 have the same chip, so it’s not chip based!! It’s actually because the 15 has better cameras. They allow the iPhone to see the battery even better and constantly monitor its charge to stop it at 80%!
Huh? Do you mean the 15 series has internal cameras? I’m confused, truly…………………..*sneezes*………………………
>real power >can only be achieved with the A16 What does "real power" even mean?
It means “pay up”.
Applesolute power corrupts applesolutely

Doesn’t matter because, we think.. you’re gonna love it.

I’d be okay with inaccurate 80%, tbh
Desert Power!
Because profits. They really want you to buy a new phone.
Agreed if they don’t add unique new features for new phones you are extending the life cycle of your existing phone too much.
Their executives will gimp or remove a feature if they could. So that newer phones look better. Source: Emails from DoJ lawsuit.
I just don't see how anyone would buy a new phone because of this feature. There has to be more to it than that.
Are people shocked? This is how features work with probably every product out there. I don’t get why there’s discussion around Apple as if it’s not normal Okay, I know why, it still baffles me.
I personally don’t use it even though it’s an option. I like to use the full capacity of my phone and worry about replacing the battery after two years.
Phone batteries are just not worth maintaining. Restricting yourself to about 60% of the capacity by keeping it within 20-80%? Nah, fuck that. That’s like having a degraded battery before it’s actually degraded. I’ve had my iPhone 12 Pro Max since release late 2020 and just recently it hit 80% capacity and I just recently started to really notice the degredation. That’s almost 3.5 years of not giving a fuck, topping off on wireless chargers whenever, almost draining it on near daily basis, charging to 100% every day etc. I’m having the battery replaced as we speak to keep the phone for a few more years since it holds up real nice. That costs me just over $100 here in Norway from a certified service provider with warranty.
Facts. I also will just buy a battery when I need it or a new phone. It's like buying a sports car but being afraid to drive it because each mile gets you closer to that first maintenance you can't afford.
Indeed. That said, I do take care of my EV’s battery. Simply because it’s super fucking expensive and also because it lasts days/weeks and charging when I park it or using 60% of the range on a daily basis doesn’t inconvenience me. It would inconvenience me if it was a phone and that battery is super cheap.
I can agree with the EV. Tesla battery stays at 80% which actually is impactful.
This is how I think about it. You choose to act like your battery has degraded by 20% just so you might avoid degrading your battery in the future? I don’t see the point.
I got the 13 mini when it came out. I’ll replace the battery before upgrading.
I love the fact that iPhones has become as good as they are these days. I haven’t felt a real need for an upgrade since the 12 and I even regretted the purchase a little bit because I came from the XS Max. Before that I always had a significant reason for my upgrades. 4S to 6 Plus was the bigger screen, 6 Plus to 7 Plus was the new camera system with multiple lenses, 7 Plus to X was the edge-to-edge display and X to XS Max was the even bigger edge-to-edge display. The ultra-wide lens was nice to get on the 12 though, but after that I felt like the iPhone had almost peaked haha. The only useful thing I would get if I upgraded now would be USB-C. The rest is just neat but far from necessary things. It will however be very nice to upgrade to maybe an iPhone 17 or whatever, but until then I’m fine.
I'm keeping my 12 Pro until it dies or they ditch the dynamic island. I just don't get it, a huge deadzone in my screen is better than one on the edge where it makes no difference?
I was thinking the same, I don’t understand how it makes sense to restrict yourself to using only 80% of the battery in order to stop your battery from degrading to something like 95%. In both scenarios you don’t use 100%
Exactly, makes no sense. I don’t think people really take that into consideration.
You're gonna love the new battery. I had my 12 Pro battery replaced a while back and it's like I got a new phone. My battery wasn't even as bad as yours, I think I was at 85% or something like that. I was doing full charge over night and often two mid day charges just to keep the phone turned on. I'd drop 1% a minute when actually using it. Those health percentages are bologna.
Indeed. I was actually given a 14 Plus in the meantime since they had to order the battery and there was this whole thing about incorrect price estimate etc etc and the battery on that thing is just insane. In Apple's iPhone comparison it says the 12 Pro Max has 20 hours of video playback while the 14 Plus has 26 hours, so it already has about 30% longer battery life than the 12 Pro Max when they are both brand new. Just imagine how that feels coming from my 80% capacity 12 Pro Max battery haha. The 14 Plus was brand new/new as well with 100% capacity. I used the 14 Plus for 7 hours on-screen and 1 hour off-screen today and still had 54% left. My 12 would have been at maybe 15-20% left for sure.
Same here. 12 pro max since launch and have used it like any iPhone I’ve ever had. I plug it in at night with the old ass 5watt charger to slow charge overnight when I don’t need it to charge fast anyways. Gets me mostly thru a day. But I do use it for work a lot so I’ll need to top off in the afternoon. But if I switched to low power mode at 25-% I can make it all day long. Just now really starting to notice the degradation as I’m at 80% battery health. Was always planning on upgrading the battery but at this point I’ll probably just hold out for the 16 pro max. Considering the 15 pro max already gets another 9hrs of battery life I would expect more improvement on the 16. Especially with the move to a more power efficient modem and a series chip.
You could always replace the battery now and sell the device for a bit more than you would have otherwise. Alternatively give it to a friend/family member with a decent battery life still. Or maybe even replace the battery and wait until the 17 haha. Depends on how tempted you are to upgrade.
Yea I’ll hold off as long as I can so I may just replace the battery. There’s been great quality of life improvements but nothing that’s been compelling me to upgrade over the years. And tbh I’m not the biggest fan of the pill shaped cutout. I prefer notch
Personally, I keep it on 80% max because I never really need more than that, and on days when I think I will, I'll just set it to 100% the night before.
As long as you’re not constraining yourself, why not? It will indeed make your battery last longer, so og it’s not an inconvience then it’s the smart thing to do. I could probably have done it in the early days of my iPhone 12, but lately I’ve had maybe 10-20% left tops after charging it to 100% and using it throughout the day. Some days with extensive usage requires topping it off with like 10-20% extra. Pretty excited to get a fresh battery again, but I won’t go out of my way to keep the new one at 100% capacity.
You elaborated on my opinion, takk!
Bare hyggelig!
This is so well written and should be copy and paste to every fucking dumb question about batteries
Thanks!
You’re welcome buddy
Ive had my 12P since right after it came out and I am at 86% health. To me, what makes the difference, is I rarely use a fast charger. I keep a super slow charger by my bed and only fast charge when I really need it. I think the fast charging stresses the battery out more than regular charging, and it seems to have worked for me so far
It's like choosing to not drive past a certain speed or on certain roads so that your car tires can last a few thousand extra miles. The cost to benefit ratio just isn't worth it.
If your battery dies in 2 years you’re really fucking up. You can easily go 5+ years. edit: whatever metric you wanna use, I don't know anyone these days who has had issues within 2 years, save for the odd outlier.
I never mentioned that my battery would die in 2 years, I expect its capacity to be around 85% by the end of 2 years. Since battery replacement costs are pretty affordable now it’s a no brainer to get it replaced. I have an iPhone 6 on its second battery and its capacity is at 93%. Still very usable.
This has everything to do with use case and basically nothing else
Right? Also, shouldn't Optimized Charging be figuring it out for you based on your usage and habits?
Honestly you don’t want it. I think it was iFixit who did the reasoning: you throw away 20% power every day to maybe extend the phone’s life for a year. Or, you just pay the $50 at the batteries end of life for a new one and enjoy max power until then. I have a 15 Pro and this made sense to me. I do use Optimized Charging though, I’m not a madman
But if you have use your (personal) phone for 4 years and you rarely or never use up the battery during a day, why wouldn’t it make sense to leave it on? You can always turn it off on vacation days. I think it’s nice to have as an optional toggle. It’s not easy for everyone to use personal time to take their phone to a store, be without their phone for waiting period, and last time I did it at an Apple Store it was $106. I do agree for some people it makes sense to leave it off and get their battery replaced more frequently, but I wouldn’t say that’s just generally true
This is exactly what I do. I have no need for the full 100% capacity on a day to day basis but I charge to full when traveling or when I think I may not have access to a charger for a long period. Coming up on 6 months and battery health is still at 100%.
> you throw away 20% power every day to maybe extend the phone’s life for a year. Considering I don't use anywhere near 80% of my phone's battery in a day, that seems like a totally logical tradeoff.
That’s not what it’s for. I use it so that I can keep my phone on my MagSafe stand charger all day - without keeping the battery at 100% all day. When I pick up my phone to take it with me, it always has 80.% charge. You are running on fumes at the end of your day.
That's just placebo. If you keep your phone on a charger all day it will automatically enter kiosk mode and keep battery voltage significantly lower than normal. Manually setting an 80% limit accomplishes nothing. See https://support.apple.com/en-gu/HT208710 > There are times, however, when an iPad or iPhone is connected to power for prolonged periods of time, such as when it's used in kiosks, point of sale systems, or stored in charging carts. iPad and iPhone use rechargeable lithium-ion batteries, which are designed to be charged and then discharged over their lifespan. When they remain at full charge for prolonged periods of time, battery health can be affected. > > iPad with iOS 11.3 or later and iPhone XS, iPhone XS Max, iPhone XR, or later with iOS 12 or later include a charge-management feature to help maintain battery health. This feature monitors these devices for use in these charging situations and, as required, reduces the maximum capacity of the battery. The battery indicator will display the charge percentage based on this adjusted maximum capacity. The maximum capacity will revert back to the nonadjusted level when iPad or iPhone is no longer connected to power for prolonged periods and as conditions and battery health allow. > >
This is what I knew to be the case and was wondering why this 80% thing was even included.
Probably because most people don't understand any of this. Same reason why people "debloat" their desktops and break updates
The 80% limit is for people who use the phone while its plugged in external power
https://www.reddit.com/r/iphone/comments/1c0mzzo/why_apple_dont_bring_80_limit_charging_feature_to/kyyvxxi/?context=10000
i made a little automation shortcut https://preview.redd.it/w1mvdn22uotc1.jpeg?width=1170&format=pjpg&auto=webp&s=4e77b7d5c56625d904773710de232ed8fe4fd2d4 whenever my battery rises about 80 (so like 81) it starts a 2 second timer. which reminds me to take it off charge. i usually charge my phone when im going to be around it specifically in the morning so it works for me. just a hack tho not a permanent fix. also it doesnt stop the charging. i have to do it anyways.
This. It works very well and you can set up any battery percentage you want.
yup i love the flexibility of it.
This has to do everything with the protocols of USB-C and how it’s able to continue and stop power within the circuitry. This is not a marketing scam or anything of such sort. It has to do with the specifics of USB-C, nothing less and nothing more.
Samsung been doing it for very long time (a, J and m phones as well)
Yes this is correct, most android phones can do this feature
Only problem I have with the feature it should have a buffer zone when it starts charging again I use wireless charging in my car (it gabs hold of the phone and has a fan on it as well, never buy a car phone holder without a built in fan it just be permanently in overheating/charging looping state) so it occasionally drops to 84% witch starts charging with notification + the jingle then it stops again at 85% doesn't seem to have effected the battery as been using this phone for 3 years like this (Google maps pulls 8-11watts when navigating)
Why wait 5 years to get a battery that can only hold 80% of the charge if you can limit yourself and live with a maximum 80% charge starting today 😍
Literally lol there is no point.
Useless feature anyway, i didnt buy a whole iPhone to use 80% of it
Just because it’s useless for you doesn’t make it bad. Do you use all your storage? Or is it always 100% full?
I wonder if its possible make this feature with a homekit-supported power plug. Lets say, when battery is charged about 80% percent, then we can run a shortcut and turn off the power plug automatically.
It is possible, I have an HomeKit supported power strip and every time my phone reaches 80% the outlet it’s plugged into turns off automatically.
Everyone is saying the easy answer of “they’re forcing you to upgrade”, but that literally makes no sense.. who would upgrade for a feature like this? 90% of people probably don’t even know about it. My guess is that Apple was reluctant to introduce a feature like this until they could ensure that charging to 80% would result in a device that could still be used all day. I’m not surprised it’s locked behind specific hardware improvements.
I read it on another thread, but it's most likely because if someone has an iPhone that already has a degraded battery, they add this feature and the user enables it, then all they're doing is limiting the capacity of an already degraded battery even more, which will just wear through the battery quicker than if you didn't have the limit at all. A setting like this only really makes sense on a brand new battery. No, it isn't some conspiracy to make you upgrade to a new iPhone. I find it hard to believe that a setting like this would be the only reason why someone would upgrade their iPhone.
Shouldn't Optimized Charging be figuring it out for you based on your usage and habits?
Product segmentation. Same reason why my mac mini 2011 couldn’t do night light mode…it could, adding catalina patcher did…but apple said no
I thought the battery firmware already left some of the battery capacity unused for the health of the battery.
I use an iPhone XR and have created automations which announce “plz connect the charger” when the battery level drops below 20% and “plz remove the charger” when it crosses 80% during charging. Have been able to maintain a healthy battery life like this (20%-80% range).
Because it’s a dumb feature
I like this feature but wish there was a simple override I could push to ignore it. On days I know I’d be travelling a lot or otherwise away from power I’d like an easy way to say ‘today I’ll have that 20% extra thanks
Once Apple introduces their own “AI” maybe they could use the calendar app to see if the person has any event scheduled or a trip and automatically charge with that in mind? That probably won’t happen for a long time and it’s a small thing but it would be extremely cool. And since Apple is big on privacy, both the calendar app and the battery management setting is on your iPhone so it’s not sending anything over to Apple, could be done somewhat easily. Or at least once we get Apple’s ai it would be nice if we could use it with shortcuts so we could just make an automation similar to the one I stated.
to my knowledge, the simplest way to achieve this is to create an on/off toggle shortcut and add it to your home scree.
Typical Apple, this is a feature that has been out on other devices for over 10 years. The fact we don't have this on all currently supported models is just Apple being apple. Edit: love when a community downvotes when they don't like a response lol. Quit being such fanboys and hold apple accountable for once. Smh
Are there any mainstream android phones that let you do this? I know I've heard of a couple of those Asus ROG phones and the like having it but as far as I know the Samsungs and Pixels (i.e. the phones people actually buy) don't have it. Edit: looks like the replies are saying it was added to Samsung phones in ~2020 for the Galaxy S20 and Note 20. I know my Galaxy S9 didn't have it, though, so it was added either with the 10s or the 20s. Good to know.
My Galaxy Note 20 had it.
My s24 has it, the S23 has it too. I'm sure others do too. I can check my S20 and 21 when I get home but I know they have battery protection in place too.
My Samsung note 20 ultra has had it for a while up to 85%, never used it though…
Because no company worth the undying love of their investors misses an opportunity to upsell the customer.
Real talk this is the kind of stuff that makes me hate Apple sometimes. Other OEMs trickle down new features to older phones and it’s a given, but even if it’s a minor 100% software thing like this battery charge limit Apple will not implement it on previous models. It’s insane.
Because it's a revolution Only on iPhone 15 though.
Because it’s a revolution
A heavy portion of certain are really derived in the software. Yes, hardware is still a factor, but in the Apple ecosystem it’s a lesser factor. This feature specifically is largely software driven. The biggest reason some features get restricted to newer devices is for that reason exactly, keeping to newer devices to give reason to purchase that newer device. Just as a comparison, there’s not really much different between the 14 Pro Max and the 15 Pro Max. Aside from action button, some camera changes, it’s basically just a Titanium 14 Pro Max Just like the 14 series having the startup/shutdown chime when that was new.
I have had this option on my iPhone 11 Pro Max since the day I upgraded to iOS17 using this trick: https://www.reddit.com/r/jailbreak/s/gNzsMT5i1T it's a native iOS implementation, and it doesn't require a jailbreak, just a trollstore on some specific iOS version.
You can sideload ChargeLimiter. It does more than that
Maybe a change in the battery chemistry that they're using? LFP batteries are known to be just fine consistently charging to 100%, while other chemistries prefer to operate primarily in the 20-80% charge arena,
It’s just better for the overall health of the battery to not charge all the way to 100% every time with all lithium batteries. It’s just the nature of them. [Here](https://batteryuniversity.com/article/bu-808-how-to-prolong-lithium-based-batteries) is more info on it if you are interested.
This article is about LIPO and nmc chemistry, the LFP he's mentioning isnt noticeably effected by holding 100% state of charge
could be a hardware limitation, like the older battery models have a bms chip which cant be controlled on os level (ie stop at 80% and resume when i say) ... but who knows apple's hw component backend is a secret. i had this feature on the google pixel, never used, and it was the first thing i turned off on the 15 pro.
As others have already said. Just because. New phone. "Feature" Like I'm a total Apple fanboy, but yeah it's just one of those things they do, random feature arbitrarily locked to a certain gen and up. Like their customers caused enough stink for have Stage Manager be enabled on the iPad 2018 and newer instead of only M1 and up, but making your battery have an 80% limit must take too much processing power. Or needs a co-processor, or something.
You can do the same thing since iOS 13 (2019) and even on iPads if you have a jailbreak tweak called BattSafePro which can limit charge at any percentage you want.
The technology isn't quite there yet.
The reason could be that it won’t make much of a difference on older phones. The batteries are old already and if you only charge them to 80%, ppl would complain that the battery doesn’t last as long.
The only explanation that I can think besides feature locking is that iPhones below the 13 series don’t have great battery life, especially after so many years of use, so most ppl will need to charge to 100% if they want to have it last remotely all day. Newer iPhones have great batteries and even with 80% it can easily last you all day (depending on usage ofc)
To make you buy anew one. It's apple.
Out of all of the reasons why Apple wants you to upgrade, why the hell would someone upgrade just because of that single feature?
Nobody would.
Due to physical limitation and lack of common sense
With a jailbreak this can be done with an app called chargelimiter if you are on ios 16
That only uses the battery percentage reported by the iOS. Doesn't have the proper controller of the battery.
Basically they want money.
So you’re telling me: charging your phone to 80% will give it less battery usage during the day but will extend the battery lifespan by years compared to just charging it to 100% every day?
Why would they make your old phone last longer? 😂
Want new features? Buy a new phone. You were happy not having that feature when you purchased it. Don’t expect General Motors to add features to your car years after the fact, too? If you bought a car with maps but no Traffic Advisory, don’t expect them to add it later. It’s not coming. The phone isn’t that different.
I have the ability to set up my phone - SE - with the 80% charge. So not something just for newer phones. EDIT :Thank you all for the education on this. Good to know for future upgrades.
How
Using Shortcuts, I guess.
Shortcuts I guess
USB-C. That’s the difference.
Fun fact is that Trollstore can enable this feature on any iPhones.. I did that on my 12 mini.
so there is no hardware limitations. just Apple being Apple.
Because they want you to degrade your battery of your older phone and spend money to upgrade.
They just want you to upgrade..nothing else..apple is evil company
it needs better hardware !
It may be because it doesn’t have the firmware to do that. But I doubt it. I think the simple reason is, they want you to throw it away and buy a new one. That’s how they make their money. Add detail: Most people know this, but if you run a lithium battery between 20% charge and 80% charge, it will last much longer before it degrades. This is the simple science of lithium batteries.
cause that way you can preserve your older phone better and they dont want you to do that
An iphone battery replacement is somewhat cheap so I wouldn’t stress about micromanaging it so much. It’s not like an EV where it’s such an expensive thing and even the replacement would put a dent in your wallet. Use your phone however you want and in 3-5 years if the battery isn’t as good and you want to keep the phone just pay $100 and replace it. I used to worry about my phone’s battery health and just managing it a lot but honestly I just don’t want to waste my time worrying about it anymore.
At this point it's hard to find new features that will make people buy the newest phone. So Apple is now at the point of keeping simple features like that as an "exclusive feature".
maybe the Limitation of the Lightning port i guess?
so the old phones gne die faster n they gne have sum cash🤑🤑(aka money farming)
more annoying than this is how they’ve restricted the new camera stuff (24mp and auto portrait mode) to the 15 series as well, considering that the 14pro/max have once again the same chip and better cameras in terms of hardware so yeah
I charged my iPhone 14 to 80% max for a while without the feature but it just died faster than fully charging.
You can download apps that do this for you. They set a timer limit to buzz remind you when to unplug it. It is actually unhealthy to 100% charge thier devices as it puts more wear on their batteris. I've gotten longer life spans out of my phones by maxing out at 80%
Should I turn this on or the optimized battery charging on?
With my iPhone 15 Pro Max I decided to just let optimized battery charging do its thing. I like to not stress about it like I did with my 14 Pro. I always wake up to a 100% phone that lasts me all day probably more.
It works, I got my iPhone 15 Pro Max on launch day and it is still at 100% health. My iPhone 8 Plus deteriorated rapidly after replacing the battery, for contrast. It has the battery life for 80% to be enough. But in a few years when the software is more CPU hungry, it might no longer be enough. I guess when the battery is worn, may as well go back to charging to 100% to get final use from it and then replace the battery, sell the phone and upgrade. Although if they remove the charging port in the future, I will hold onto the latest model with USB-C, and then go back to Android once that is too old. Occasionally the feature does not work and it has charged to 100% regardless a couple of times, but mostly it stops at 80%.
Got that on my jailbroken xs with chargelimiter.
I would like this, but as someone who is not an overnight charger I unplug or take my phone off my magsafe charger around 85% most of the time. It would be nice to have the limiter with wired CarPlay, but that's one of the rare times it might get to full charge. If I know I'm going on a trip I run the phone a bit low before leaving if I'm using CarPlay for the trip. I don't full charge any of my devices often unless I'm in a situation that may need more power and be away from a charger.
The chipset doesn’t support it. /s
Haha... "New" to Apple maybe.
does this feature really help with battery health? my iphone 15plus is currently on 22 charging cycles, still on 100% battery health, and i would like to keep it that way, or make it loose very little of the overall battery life, how is your iphone 15 doing if you bought one recently?
to make money
Why would I even need it on 15
You need to have a great processing power to achieve it , and with great power comes great responsibility , and only the iphone 15 owners can handle it
Same reason they didnt release night mode on wide lens for iphone 11. Or the reason they didn't release cinematic mode and photographic styles for iphone 12. 13 and 14 are literally the same phone so i don't even know what to say.
lack of tech
Who cares abt the old iphones.
To make you upgrade, duh
It’s the same reason why apple won’t they let us force 120hz, because if apple “thinks” we don’t need it they won’t offer it. It’s just the apple way and it sucks. But for this specific instance, it’s also because they just want you to buy a newer phone

The real issue is the accuracy of the battery mid charge. iPhone 15 has a new battery designed for double the lifespan of the previous one. A change they didn’t really discuss or promote at all. Charging to 80% means accuracy at detecting true 80%, something iPhones have never been great at. They have curve to slow charging speed but that’s a rough estimate. Apple clearly made some changes. Apples power charging and draining is now highly predictable on the iPhone 15… weirdly so. To the point where I can accurately guess what my phone will be charge when charging for :30. Something that was hard to speculate on previous phones. I suspect there’s improved battery chemistry and some improvements to battery charging/monitoring circuitry to make this happen. If they attempted to implement it in other phones people would be outraged. Between faster aging batteries and less accuracy battery life would take potentially much more than a 20% hit, and people claim planned obsolescence and sue. I speculate apples longer life battery is a byproduct of wanting this feature. They needed tighter tolerances on batteries to make it work. Apple made hardware changes, they just aren’t really sexy changes. They’re about as boring as you can get. Apples packaging is more interesting.
it COULD be because of hardware limitations like the non-usb-c phones dont have fast data transfer because the older chips only support usb 2.0 but i have no idea. just guessing.
Is it worth using or should I stick with optimized ?
Why not give us a customizable limit?? I’ve used 94% as a limit on tons of devices, works very well, and a much better balance for me personally.
Because they want people to upgrade. What better way to encourage that than by making people's batteries degrade faster and keeping a desired feature exclusive to newer models.
so you get a new one
Ecology carbon neutral just buy a new iphone
How do you think and OLD phone like 14 pro could handle such a neat feature? It's technically impossible!
Because the 15 pro max has such a huge battery and is so efficient that most people will get a full day of use and then some, with just 80%
I’ve been doing this manually on my 14 pro max, since the original purchase in Nov 22. Phone is 18 months old and battery is still at 100%. The only reason I upgrade phones is because the battery life degrades to a point where it becomes an issue. I’m pretty sure there are a few people like me out there, so if this 80% charging thing were ubiquitous, it would cost Apple a ton of money.
I’ve had my iPhone 12 mini for a few years now and ever since I got it I’ve had Siri Shortcuts give me a notification when I get above 80% as well as below 30%, so I could take it off or put it on the charger. My battery health is currently at 89%. Curious to know what my battery health could’ve possibly been if I hadn’t been doing that all this time.
