"Basic" Battery Protection Mode Not Working

[Theo5620]

it keeps the phone charging up to 100% all the time

You're not being clear about what you want. If you have a gripe about how your phone charges, submit feedback to Samsung developers.

Love my 85% stop charging.
I've paid dearly for swollen battery twice its size & damaged screen on older models.

Basic battery protection just means your battery will charge fully, but be prevented from overcharging (charging will stop when the battery is full and resume when the power level drops below 95%).  Unless you are watching every minute of your battery charge cycle you will not notice when the power drops and charging resumes.

Adaptive battery protection will only charge to 80%  while you are asleep (I assume with sleep mode on - or it just decides what normal sleep hours are).

Maximum will only charge your battery to 80%, and not resume charging.  I am unsure whether it resumes charging if it goes below 80%..

I, personally, keep battery protection off and fully charge my phone every night, with no ill effects.  The battery still stops charging when full, and my phone is at 100% each morning.  I assume that even with battery protection off, basic battery protection is *still* always in effect.

For example, if I leave my phone charging overnight, it’s really bad for the battery when the phone keeps receiving power after it’s already at 100%. That’s where the “Basic Battery Protection” feature comes in — when the phone reaches 100%, it automatically stops charging, and then the battery starts to drop. When it gets to 95%, the phone starts charging again, so that when I wake up or unplug it, the battery is at 100%. But this feature doesn’t work — the phone keeps receiving power even when it’s already at 100%.

Submit feedback about the "basic" feature not working as described, or use the adaptive feature for overnight charging.

 as you can see here I'm not the only one with that issue also there are more posts on that issue here and on reddit

I regret buying this phone,  my next phone won't be a samsung that is for sure,  I can't believe that a simple but crucial function is not working.

@Theo5620 it does work but just not the way you are thinking. Read this. I tried this and it works as mentioned.

Battery Protection only allows the phone to charge to 85%. It will only charge to 100% with it turned off. I know the phone stops charging automatically once it reaches 100%.

[cavalier10212]

@JeepGuy95 this is about basic protection not maximum protection. Basic protection allows charging to 100% and then keeps it there unless the battery utilisation exceeds and then let's it fall to 95%.

Maximum protection limits the charging to a specified percentage like 80,85,90,95.

The two things are different
