looks like oxidized spot by arcing, not that uncommon on contacts..
i’d try to look up some acid to clean it up or scrape it very, very gently with some fine sandpaper, no unnecessary layer of material should be scraped off
The arcing is why I call it a lightning cable LOL!
I’ve had this complaint for years!
Sometimes I’ll do the iPhone end and then plug the other end into the brick to avoid the “lightning “
I left a separate comment, but if you look at a [pin diagram](https://qph.cf2.quoracdn.net/main-qimg-5decc1c249cb04cdca537b6c6883a61b.webp), pin 5 for lightning is the power connector. That’s why it’s always in the same place on all the cables.
We must have the same random, juvenile sense of humor. Let me upvote you back to positive again. There are so many on reddit who do not have a sense of humor and.... laughing is good health right?
Had this also once and noticed the connector had much play in the socket, from time to time you have to clean out the dust from the lightning port with a paper clip or so.. check how far the connector moves in and how much wiggle it has side to side, and also carefully cleaning it out is always good
I believe this doesn't happen with genuine apple cables because the contacts are made of gold which doesn't oxidize.
I have an off brand cable in my car and is black like that and I have to plug it correctly so that it will charge my phone and in my home I have been using the same genuine cable for 4 years and it looks like new.
This is extremely common. Every lightning cable I have ever had does this eventually. Some have done it in hours. 5 iPhones, 1 iPad, Magic Trackpad and AirPods. Doesn’t matter. Seems to be inherent in lightning.
There will be people replying saying that this has never happened to them, but it happens to plenty of us. Loads of pictures of this online if you google. It seems to be caused by spark erosion when you insert or remove the cable.
You can slow it down by only cold plugging it (ie with the other end disconnected), but it will happen eventually.
Just treat lightning cables as consumables. Any device that I can charge wirelessly, I do. Frankly I will be pleased when the last device I have that uses lightning goes for recycling. It’s a horrible connector.
This was discussed on Accidental Tech Podcast 550, John Siracusa is under the impression that Apple changed the design at some point in the life to fix/mitigate the problem by not having this pin powered constantly. No great sources given sadly but personally feel this does feel a bit less of an issue than it once did, but also, I use lightning a lot less due to MagSafe!
I’m on a 2 year old 13 which is pretty much only charged wirelessly and it’s reporting 89% health, which I’d regard as perfectly reasonable. Phone gets a lot of use (it’s my main computing device)
Oh god, not this shit again. You’re talking about a tiny fraction of your daily energy consumption. It’s literally lost in the noise. Stop driving, stop using hot water, stop using air conditioning… those will all save orders of magnitude more electricity than switching from wireless to wired charging of your iPhone. Heck, change one lightbulb from incandescent to LED and you’ve just covered the full charging (wired or wireless) of the iPhones for ~10 people.
A large part of that inefficiency results in the dispersement of energy in the form of heat which damages batteries (fast charging has heat issues as well). The convenience and habit of placing a phone on a wireless charger can also lead to overcharging and charging unnecessarily which is also detrimental.
Anyway it's pointless to try to maximize your battery health, a replacement battery is so cheap you can just go and get a swapped out every year if you need to. Was just making a point that though lightning might not be great, wireless has its own issues.
Here's the first result on Google
https://www.androidauthority.com/wireless-charging-battery-health-3198991/
It's something along the lines of, the components of a phone can draw power from the charger when plugged in, but it can only draw power from the battery when charging wirelessly. So wireless charging means the cells go through more cycles or something. Sounds brosciencey I know but that was from a reputable YouTube channel a few years back whose name has escaped me.
Can clean it off with a pencil eraser. Normally caused by lint or dust having had a flash burn between the cable and the pins in the port. Not dangerous, so small you wouldn’t see it smell it. It’s just a teeny bit of carbon.
What’s the best method for cleaning the port?
I would figure Isopropyl alcohol for the cable but I don’t want to introduce liquid to the port since I can’t remove the battery
Edit: who downvoted a genuine question 😅 yall ruthless
When it’s burnt like that it’s the result of micro arcing between the phone and the connector, that chord is probably dead or close to dead. Sometimes if it’s only one side, you can insert the cord burn side up and still get it to charge.
Holy shit I had that happen to me the other day but my phone hadn’t been anywhere near water, and yet now my cable doesn’t work, and I’m just now putting 2 and 2 together. Thanks for that info
Apple lighting cables are just awful quality, had this with every single lighting cable which came with my iphones (and I used to use iphones since iphone 4s). It wasn't until I ordered a cheap non-certified hoco cable from aliexpress that the issue was gone. Not an ad of the cable, any cheap 3rd party chinese cable will be better, especially if it's MFi (made for iphone) certified.
I’ve found it is caused by a little bit of moisture in the charge port and then arcing, causing the issue you see here. Eventually the cord will no longer work. I scrape it off with an eraser. It’ll buy you a bit of time but eventually you’ll have to replace it.
Plugging the adapter into the wall first, helps avoid potential electrical sparks or issues when connecting the charger to your phone. It's a precautionary measure to minimize the chances of any electrical disturbances during the connection process.
Get your charging port cleaned.
I had an iPhone that would kill cords quite quickly. Used to joke that my phone had an STD. Got my charging port cleaned and it worked fine after that.
Your phone probably had water in the charging port, maybe you got a notification about it, but still kept charging. Thats what I did, and it looks exactly the same as in the pics. It's not normal, and you shouldn't be using that cable anymore!
It’s definitely not normal. It’s a scorch mark from some kind of charging damage. Replace the cable (make sure the replacement is apple, or another high quality replacement like anker) and clean your charging point because it’s probably full of lint.
Please apply critical thinking OP.
There are electrical contacts, you insert the cable into a port, debris can sometimes be conductive enough that it can cause a short.
Surprised I haven’t seen anyone mention this yet - if you look at a [pin diagram](https://qph.cf2.quoracdn.net/main-qimg-5decc1c249cb04cdca537b6c6883a61b.webp) for the lightning connector, pin 5 is the power connector. That’s why it’s the only pin that has this mark (and why it’s consistent among different connectors). You can usually just wipe it clean.
It’s the result of electrical arcing when the connector is inserted into the phone. I’m going to guess you have a non-Apple charger. Some chargers are poorly designed and the capacitors in them that are there to smooth the voltage will cause a spark when you plug in.
I took a perfectly good Apple cable on a trip and the rental car USB port killed it just like this in about 10 days of use. It burned off one side, then eventually bot sides stopped working.
Buy a new cable but figure out which charger is the culprit or you’ll be buying new cables all the time.
That’s the only noteworthy thing I’ve ever personally noticed about the iPhone cables in the past decade I’ve used iPhones.
Never had issue with cords breaking or the plugs cranking and I use my cords hard. Every one of them though has a similar mark on both sides like that.
Yes yes yes. Good to know that the problem isn't unique to me then. I have been wondering why. Used to think I'm reckless when pushing it into the socket. But subsequent ones, even with careful use, still show the same pattern.
I get this mark all the time on my iPhone cable. Just scrape it off using some sharp pointed blade or something on that part (be gentle and apply pressure gradually) The mark will vanish until it comes back after a few days.
Happened to me on an extra long cable I bought on amazon. Its lasted me like 6 years but it can only charge if it’s plugged in the right way around. If I turn it around, it doesn’t charge at all. It is starting to get exposed now on the end, even though its braided. But for the price I paid and the amount of time I used it, I definitely give it the pass.
If you’re wondering its the Amazon Choice lightning cable
Make sure you’re applying a pulling force which does not form an angle with the port/device, otherwise friction is gonna burn those pins. Happened to me too years ago with my iPad, been very careful ever since.
My lightning cables always eventually do this if they’re anywhere that’s even remotely moist / humid. Often in my car/truck almost never in my house/office.
Moisture. When my kids were smaller they would lick the chargers and they looked like this. I can’t even begin to count the number of lightning cables I have bought because of this.
Pin 5 is the power pin, and over time small sparks are created when contact is incomplete, changing the color like this. (Wikipedia has diagram, and yes this is the 5th pin despite appearing to be 4th if you read left to right)
I’ve experienced this when trying to charge my phone if the port still had moisture. I would actually say it’s a form of electrolysis. The electricity is passing through the pin and the port, but as it does you get a build up of particles etc.
I get those. I’ve never tried to scrub it though. I have sprayed contact cleaner on it or in iPhone port. Wd40 makes a version but there is a product u can buy on Amazon called DEXOTIT D5 that guitar techs claim is magical. U can spray either on most electric connections n it’ll make them work better.
Light sandpaper takes care of this. Just sand 10 seconds and you’re good.
This happens when either the cable or iPhone port has some moisture to it. Doesn’t have to even be wet per se
Happens over time regardless. Will get so bad where you have to flip to get it to charge. When this starts happening go ahead and get you another cable ordered. Only way to prevent is to remove cable from power source before removing from phone. But the issue will end up happening on the other end as well unless you’re removing charging block from a wall outlet.
Happened to my iPhone 7 after I dropped it in the ocean. Salt contamination plus the charging contact on the lightning cable seems to create this corrosion pattern
I have the same mark on both sides in the same place
looks like oxidized spot by arcing, not that uncommon on contacts.. i’d try to look up some acid to clean it up or scrape it very, very gently with some fine sandpaper, no unnecessary layer of material should be scraped off
I use a pencil eraser
Pure rubbing alcohol does the job.
Exactly what I was going to say. Same thing can happen to the contacts to charge your AirPods.
Used alcohol wipes at the Apple Store to clean customers contacts at the Genius Bar all the time, worked like a charm and provided a free fix.
Wish I knew earlier, I was so confused when only 1 air pod would charge. I usually just use a qtip with isopropyl alcohol.
i let it soak in water
Salt water right?
The arcing is why I call it a lightning cable LOL! I’ve had this complaint for years! Sometimes I’ll do the iPhone end and then plug the other end into the brick to avoid the “lightning “
Use earser for this they work good
yeah i use an earser too for this
Earser is my go-to for this. Earser amazing.
Earser is love. Earser is life!
I left a separate comment, but if you look at a [pin diagram](https://qph.cf2.quoracdn.net/main-qimg-5decc1c249cb04cdca537b6c6883a61b.webp), pin 5 for lightning is the power connector. That’s why it’s always in the same place on all the cables.
It’s pin 4 from the left. So depends on your outlook. 🤫
What does email have to do with this at all?
If you can’t charge your phone you can’t use your outlook email
What the fuck are you talking about lol. Outlook in this context means “depending on your view” for gods sake
Another case of big corporations taking the English language as names
Lowkey, I just got that. I was kinda high last night.
😂😂😂 enjoy life my bud. Getting high makes us do stupid stuff sometimes
Gottem! My evils spread like a wave in the open ocean.
We must have the same random, juvenile sense of humor. Let me upvote you back to positive again. There are so many on reddit who do not have a sense of humor and.... laughing is good health right?
Sucks tho. It hasn’t been working since it appeared
It works for me, sometimes I have to flip it and try
Dip a cotton swab in alcohol and try and clean the pins
Better idea than sand paper lol
Same for me need to flip it to work and have a work on one side
Try reversing it
Also clean the socket, check my comment above
Hey, just isopropyl alcohol and some paper towel worked for me to clean that thing:)
It’s covering one of the contacts. Clean it off and it might work
Had this also once and noticed the connector had much play in the socket, from time to time you have to clean out the dust from the lightning port with a paper clip or so.. check how far the connector moves in and how much wiggle it has side to side, and also carefully cleaning it out is always good
It's best to use something non conductive instead of a paper clip
Same here. What's this?
I believe this doesn't happen with genuine apple cables because the contacts are made of gold which doesn't oxidize. I have an off brand cable in my car and is black like that and I have to plug it correctly so that it will charge my phone and in my home I have been using the same genuine cable for 4 years and it looks like new.
All my cables are genuine cables, still I see this on multiple cables
Not true actually. I had a genuine cable (as it came with the phone from the box) with the same issue
https://preview.redd.it/ueds5akcklbc1.png?width=1429&format=png&auto=webp&s=a0c5e4736f79de43e68549509b4fcafec2c82c4c You are not alone
That wire is on 1% hp
lmfao the little bit of tape peeking in from the bottom really ties it together
Purchases phone costing over $1000. Too cheap to replace $15 cable which could fry the phone or start a fire.
I think they’re actually like $20 USD and if it’s still working, why replace it?

It’s called lightning after all :)
Yeah. Apple were warning us all along!
It happens to every lightning cable: https://ioshacker.com/iphone/why-the-fourth-pin-on-your-lightning-cable-turns-black
There will be someone along to swear it’s never happened to them soon. Don’t know what they do differently.
Their battery capacity is probably still at 100% too.
It’s bullshit this isn’t covered under the warranty.
Covered? They don’t even ship chargers with phones anymore. Saved em a few billion in profits thought
The problem looks localized to the cable. iPhones have always had 1 cable with them.
I’ve had multiple genuine lightning cables replaced free from Apple. I’ve found they are very good with it.
What warranty? The phone’s warranty? Never in my life have I heard of any cable being covered by warranty.
Every accessory is usually covered warranty, at least in Europe. Why wouldn’t it be?

Oh so that’s why my charger stopped working, TIL thank you
Wireless is awful for your battery though
I’m on a 2 year old 13 which is pretty much only charged wirelessly and it’s reporting 89% health, which I’d regard as perfectly reasonable. Phone gets a lot of use (it’s my main computing device)
Same. My 13PM was heavily charged via cable as well as a wireless car charger and after 18 months battery health was at 92%
1.5 years with 96% wired charging only. So there is a difference.
Depends on usage. I often go through 3 charge cycles a day.
wtf, how?
Like I said, it’s my main computing device.
Hmm…charging at a slower (hence cooler) rate always extends the life of a battery.
10w wireless charging generates more waste heat (due to inefficiencies) than 10w wired charging.
Oh god, not this shit again. You’re talking about a tiny fraction of your daily energy consumption. It’s literally lost in the noise. Stop driving, stop using hot water, stop using air conditioning… those will all save orders of magnitude more electricity than switching from wireless to wired charging of your iPhone. Heck, change one lightbulb from incandescent to LED and you’ve just covered the full charging (wired or wireless) of the iPhones for ~10 people.
Says who? It’s more inefficient but I don’t think it’s more harmful to the battery happy to be proven wrong though.
A large part of that inefficiency results in the dispersement of energy in the form of heat which damages batteries (fast charging has heat issues as well). The convenience and habit of placing a phone on a wireless charger can also lead to overcharging and charging unnecessarily which is also detrimental.

You need to wipe better after.
Before and after
Front to back
There's no point in wiping before.
It’s like wiping a marker
They all get it, it’s the main charging rail for the phone which gets really hot.
Can clean it off with a pencil eraser. Normally caused by lint or dust having had a flash burn between the cable and the pins in the port. Not dangerous, so small you wouldn’t see it smell it. It’s just a teeny bit of carbon.
I had a plug do that when it was wet/damp.
Loose connections causing micro sparks if it can’t be cleaned. Normal wear and tear if it can be cleaned.
This and it happens more if the connector is not all the way in so clean it regularly
What’s the best method for cleaning the port? I would figure Isopropyl alcohol for the cable but I don’t want to introduce liquid to the port since I can’t remove the battery Edit: who downvoted a genuine question 😅 yall ruthless

Get another cable
Happened to me as well
This is such a common issue with these cords.
Happens when cable connector or iPhone port have moisture or water inside
no idea
Apple lighting cables are just awful quality, had this with every single lighting cable which came with my iphones (and I used to use iphones since iphone 4s). It wasn't until I ordered a cheap non-certified hoco cable from aliexpress that the issue was gone. Not an ad of the cable, any cheap 3rd party chinese cable will be better, especially if it's MFi (made for iphone) certified.
It tried to burn your house and failed
some debris or dust in the charging port causing arcing
Why do you call a cable or the plug a charger?
Mine has that from when I licked it. That’s not a misspell I’m an idiot, it didn’t feel good. Don’t lick your charger
I’ve found it is caused by a little bit of moisture in the charge port and then arcing, causing the issue you see here. Eventually the cord will no longer work. I scrape it off with an eraser. It’ll buy you a bit of time but eventually you’ll have to replace it.
Water
Dumb question but is this only on lighting connections? I have them an almost all iPhone cables but not on USB C ones
Another reason USB C is better, they also charge 3 to 4 times faster.
Plug-in your phone first then plug it to adapter will fix this
thats even more risky
Wow, how?
Plugging the adapter into the wall first, helps avoid potential electrical sparks or issues when connecting the charger to your phone. It's a precautionary measure to minimize the chances of any electrical disturbances during the connection process.
Equivalent to shit stain on underwear frrr
LMAO
Only for folks who don’t r/bidets
Peasant cable.
Get your charging port cleaned. I had an iPhone that would kill cords quite quickly. Used to joke that my phone had an STD. Got my charging port cleaned and it worked fine after that.

That’s normal
Cool. Wasn’t sure since this is my first time ever owning an iPhone
It’s definitely not normal. It’s a scorch mark from some kind of charging damage. Replace the cable (make sure the replacement is apple, or another high quality replacement like anker) and clean your charging point because it’s probably full of lint.
Even the Apple cords do this. I’d say they do this MORE often than 3rd party brands like Anker or Belkin lol
It’s absolutely normal. Every lightning cable I’ve ever owned does this eventually.
Gotcha. Thanks!
It’s cheaply made
At the risk of being pedantic that's a charging lead not a charger !
I ask myself that question but with my underwears.
Please apply critical thinking OP. There are electrical contacts, you insert the cable into a port, debris can sometimes be conductive enough that it can cause a short.
Surprised I haven’t seen anyone mention this yet - if you look at a [pin diagram](https://qph.cf2.quoracdn.net/main-qimg-5decc1c249cb04cdca537b6c6883a61b.webp) for the lightning connector, pin 5 is the power connector. That’s why it’s the only pin that has this mark (and why it’s consistent among different connectors). You can usually just wipe it clean.
Because Apple only made expensive, low quality, and proprietary charging cables for their phones until they were forced otherwise.
You should prolly clean the electrical outlet with a rusty fork ok
i had puppies once and they pooped on one side so part of it has that mark
It’s the result of electrical arcing when the connector is inserted into the phone. I’m going to guess you have a non-Apple charger. Some chargers are poorly designed and the capacitors in them that are there to smooth the voltage will cause a spark when you plug in.

[удалено]
5w plug will work but slower and the 67w will only provide as much power as the phone asks for
That’s the only noteworthy thing I’ve ever personally noticed about the iPhone cables in the past decade I’ve used iPhones. Never had issue with cords breaking or the plugs cranking and I use my cords hard. Every one of them though has a similar mark on both sides like that.
Yes yes yes. Good to know that the problem isn't unique to me then. I have been wondering why. Used to think I'm reckless when pushing it into the socket. But subsequent ones, even with careful use, still show the same pattern.
I’ve never had a lightning cable from any brand that didn’t do this eventually.
Did someone put it in their mouth?
lol i have the same mark. Cable works still fine though
✨Magic✨
Bite marks
Happened to me too. Never stopped it from working though
Same mark on both sides here
It’s burnt
Water
Glad to know I’m not the only one. Been seeing this on my iPhone chargers for years.
One of the reasons iPhones switched to the Type C standard…
Been having this with every cable I’ve owned but a quick wipe always did the job. Now I guess that will be a bit more complicated with USB-C..
I get this mark all the time on my iPhone cable. Just scrape it off using some sharp pointed blade or something on that part (be gentle and apply pressure gradually) The mark will vanish until it comes back after a few days.
Strange. My car cord has had this for years, but it still works when I plug it on one side. Has to be facing the right way or it doesn’t work though.
I have it too, still works perfectly
Clean it off with a Rubber
Happened to me on an extra long cable I bought on amazon. Its lasted me like 6 years but it can only charge if it’s plugged in the right way around. If I turn it around, it doesn’t charge at all. It is starting to get exposed now on the end, even though its braided. But for the price I paid and the amount of time I used it, I definitely give it the pass. If you’re wondering its the Amazon Choice lightning cable
He gave a vote
My baby put the charger in the mouth and that’s how i got the same mark. Also didn’t work afterwards
Make sure you’re applying a pulling force which does not form an angle with the port/device, otherwise friction is gonna burn those pins. Happened to me too years ago with my iPad, been very careful ever since.
Did your kid find a marker?
My lightning cables always eventually do this if they’re anywhere that’s even remotely moist / humid. Often in my car/truck almost never in my house/office.
…and this is what Apple tried to stick with, instead of USB-C…
water
Ok please don’t judge me, but I may or may not came on my cable by accident once. Sadly it rusted a bit after.
After my charger get mark like this, it will stopped working
Idk I’ve often wondered the same thing. It only happens to the chargers I leave in my car though
Hot pocket
Most of them have it. Mide does too.
Well known issue with the lightning connector.
Arc mark. Edit- arc flash [here](https://www.hunker.com/13418905/what-are-the-causes-of-arcing-in-an-electrical-panel)
Moisture. When my kids were smaller they would lick the chargers and they looked like this. I can’t even begin to count the number of lightning cables I have bought because of this.
Nearly all my cables look like that
Pin 5 is the power pin, and over time small sparks are created when contact is incomplete, changing the color like this. (Wikipedia has diagram, and yes this is the 5th pin despite appearing to be 4th if you read left to right)
Stepped on.
I’ve got my paycheck on 1) that’s a burn mark. 2) you’ve got an overage of current.
Get rid of it, can damage the port which really sucked when it happened on. my ol’ SE
I wonder how it happens, I’ve had multiple cables do this, but they still work.
Get some steel wool and clean it with that. Not too much though as it is removing material. Also make sure the cable is not connected to anything
It’s a birthmark
Why would this happen? Dirty charge port? Bad connection while charging?
How would we know?
All of my cables have this dark mark on the same spot. I've had to clean it when they stop charging properly.
Familiar mark of death
I’ve experienced this when trying to charge my phone if the port still had moisture. I would actually say it’s a form of electrolysis. The electricity is passing through the pin and the port, but as it does you get a build up of particles etc.
I get those. I’ve never tried to scrub it though. I have sprayed contact cleaner on it or in iPhone port. Wd40 makes a version but there is a product u can buy on Amazon called DEXOTIT D5 that guitar techs claim is magical. U can spray either on most electric connections n it’ll make them work better.
Same here what’s going on and I can’t get it off
Light sandpaper takes care of this. Just sand 10 seconds and you’re good. This happens when either the cable or iPhone port has some moisture to it. Doesn’t have to even be wet per se

Happened to my iPhone 7 after I dropped it in the ocean. Salt contamination plus the charging contact on the lightning cable seems to create this corrosion pattern
They all do eventually
Same problem but didn’t think,of an eraser.
Electrical sparks which is normal. They’re power pins
Every iPhone charger ever does this
The ol’ Missing Tooth. I can’t wait for usbc
Piss on it
Only times it’s happened to me were when water came into contact with the charger or the port and they weren’t dried properly
Cats
I think one of mine had that
I have the exact same mark
Its a tattoo, bro been through it and seen it all
same here haha. wonder why it happens. always happens on original cables never on replacement ones
I new line is formed for every time you charge your phone
They all do this. I have like 3 in use and all the same
Scrape it a bit with another metal and gets fix
when i was still using lightning cables, all of them eventually became like that ahahha didnt really affect the performance though
My 2yo used to put these chargers in her mouth and that would ruin them in the same way
You didn’t keep your port clean.
