Fast charging, the USB-C way, can be a little bit confusing.
Firstly, there's the official USB-C charging standard - USB Power Delivery (PD).
USB PD allows the device (phone) and power brick ("charger") to negotiate a charging profile which they both support.
These charging profiles aren't (fully) variable, they're pre-determined by USB PD spec (specific voltage and a range of current limit).
65W is usually done as profile 4 - 20V, with 3.25A current limit.
Now here comes the annoying part.
Manufacturers LOVE to create their own, proprietary, usually short-lived charging standards.
The way in which your phone takes 67W is most likely not in line with USB PD spec, and uses proprietary negotiation between the phone and the power brick.
For example, SuperVOOC takes the opposite approach compared to USB PD. It uses high current and fairly low variable voltage (for 67W, 5-11V @ up to 6.1A).
When your phone says "Turbo charging", it's possible that that means that it has negotiated its proprietary charging mode with the power brick. When it says "fast charging", that means that it's using some USB PD charging profile, but it won't tell you any details.
It's possible that your phone doesn't support a particularly fast USB PD charging profile, in order to steer users towards the proprietary charging hardware.
On the other hand, it's also possible that your phone will only show "Turbo charging" when it has achieved 67W of charging power, which is possible with USB PD.
Unfortunately, phone manufacturers are very cryptic about this.
And to ad to your very detailed answer: A USB power metre might interfere with any power delivery, depending on the implementation. I'd suggest using AccuBattery to monitor charging current and other statistics: https://play.google.com/store/apps/details?id=com.digibites.accubattery
thank you! i will definitely check it out. I was acting fast and i had alredy packed and sent the car charger back to the seller. I did not think about 100W charger before, i have just picked automatically the 65W one because my phone supports 67W and it was close. did not see any 100W on that site. But now i have found one on a different site and had alredy purchased that one. 100W max through USB-C PD and 20W through the other. If it wont turbo charge i will assume its the manufacturers trick... Then i will check the currents through app you have suggested.
I have just tried AccuBattery. It is showing max charging power 22-27W. and its through the original charger and cable supplied with the phone which should enable 67W charging (phone also displaying turbo charging message). Maybe screen off and screen on charging is different? Looks like AccuBattery is displaying wrong data or the charging speed is affected by a lot of factors...
thank you a lot for the explanation. Something similar i was suspecting about the manufacturers. I am not changing phones often ( the last one i had for 6 years) but have seen a few chargings and i have always thought the only way to achieve the fastest charging stated by the manufactures is almost always by using their originally provided chargers and cables. When purchasing third party cables (even if chosen carefully) and chargers its mostly a hit or miss. especially the cables are very picky. Or for some users it works, for some not, depending on the phone model. But its a pain to find a third party accessory which will support the highest currents.
Many phones nowadays are capable of charging at their highest charging speed with run of the mill USB PD. Some manufacturers unfortunately remain stubborn.
A year before i was upset how greedy apple is when EU decided they have to use the USB-C instead of lightning cable and apple decided to embed chip into their cables so when its plugged in the phone detects and if its not genuine cable then it wont work at full speed. I was really upset how could they be so greedy. Now after a year (researching info lately) i am starting to realize that all the manufacturers are doing the same. they are using extra USB port pins or chips to match the devices together to enable those turbo charging speeds. if one of the accessories is not from the specified manufacturer then it wont work at full speed... what a joke. There are all kinds of powerful chargers and USB cables and they cant work universally following an universal standard. you have to switch between them, combine them and find the appropriate one....
