It shouldn’t.
The charger part is inside the phone and should be regulating the charging process.
It’s a matter of demand and supply. You car charger can supply enough but your phone will only ask what it wants or needs.
Your car charger can output a total of 15.5 Watt, 5V x 3.1A.
While using just 1 output the maximum current is only 2.4A or 12 Watt.
If you’re using the 2 outputs the maximum output will be the full 15.5 Watt divided by the 2 outputs.
I’m wondering if that’s true.
Not the battery improvement part but that you should only charge it till 90%?
Isnt that already configured inside the charging algorithm of the phone?
Just wondering btw.
I know the car charger charges about Twice as fast. That was my concern, that charging Twice as fast would not be good for the battery? As long as it won’t shorten the batteries life, that is all that matters.I got the Phone/battery on August 19,2017,almost 1 year old.
It was also suggested to me to NOT charge the phone to 100% . Their first recommendations was to charge 80-discharge to 30. Also told me that 90% and 40% would lengthen the life of the battery. that is what I do. Most times I charge it when its b/w 40% and 50%
Wolfdog,
you should get 500 cycles out of a liion battery. That means daily charging after two years you have a weak battery.
The 40 to 90% charging extend the life
For occasional-use flashlights, I charge to about 4.1v. That gives me a 90% charge, and probably doubles the life of the battery. I charge to a full 4.2v if I know I will be using the light soon, and for a long period of time. Leaving cells sitting around at full charge isn’t the best practice if you want your batteries to last a long time. 4.1v is a lot easier on them. You could go lower, but at some point you have to trade off capacity and battery life. IMO, 4.1v is a good trade-off.

That’s what I’m wondering too.
When you phone says 0% it’s a bit above that. Not sure about 100%
I charged up an older phone to 100, then removed the battery and tested it on my DMM. It measured 4.20v. So, at least on some phones, 100 charge means a full 4.2v charge on the internal battery.
It makes sense, too. The phone manufacturers don’t care if the battery lasts 2 years or 5 years. They want you to buy a new phone every 2 years, whether you need it or not. If the battery is dying after 2 years, all the better for the phone manufacturers, since that will incentivize people to just buy a new phone (or fork over a rip-off price for a new battery).
That’s fine if it’s a lithium-ion cell designed to be charged to 4.3v. Otherwise, they’re really over-charging it just to squeeze out a bit more capacity, and that’s going to affect the life of that battery.
I could be totally wrong but I am just using logic. If the nominal voltages go up,I am thinking the maximum voltage goes up.
I am sure someone on here knows the answer to that. I have basic knowledge for 16340,14500,18560 ect. Li. Ion rechargeables , not really familiar with these phone batteries that have different nominal voltages.
Where is Professor Gauss when we need him!! lol!!!
It’s about a certain margin. It’s no law that margin changes with the voltage in a linear way.
With new tech the margins could change along with voltage.
