Don't think I'm imagining this, used to be able to charge to 85% then the battery protection would stop the charge. Now it's stopping at 80%. An annoying change.

Adding to my list of things I've noticed so far:

Battery protection charge limit,
Can't put the hide keyboard button on the left,
Nauseating shifting home screen on close apps.

Yep 80% by design.

Anyway, that's because Apple has it that way too.

Yes, it is by design to not fully charge the battery to prolong its life.  However the question is how come it changed from 85% to 80% just recently.

Presumably because Samsung developers have changed it.

Not a very helpful response, really. Obviously the developers made the change. The question is why? Have they discovered there is some issue with the battery that requires limiting to 80% vs 85%; is it just a marketing exercise to match Apple; how do we get around it?...

Etc...

I don't get it. If the whole point of this is not letting it 'overcharge' when at 100% because this will lower battery life - why not make it stop at 99%? But now they lower it to 80%? Why? It just doesn't make any sense. Especially considering that discharge wear gets heavier once the battery drops below 20% (at least that's what I keep reading). So I am at a point where I am considering turning this option off altogether and simply checking my phone when charging. Since I never charge my phone overnight, I truly believe this is the best option as of now.

"If the whole point of this is not letting it 'overcharge' when at 100%" - that isn't the reason. Regularly charging lithium-ion batteries to 100% is one of the biggest factors that lead to shorter lifespan.  Capping the charge at 80 or 85% ultimately reduces wear on the battery and maximizes performance

Thank you for posting this.  I couldn't figure out why my phone suddenly started charging to only 80% vs 85% like I've been accustomed to.  I'm guessing it's either: 1) They learned 80 is better on the battery than 85; 2) They like arbitrarily changing things to mess with us, or; 3) It makes them more money by somehow making our non-removable batteries wear faster and we have to buy a new phone sooner.

And yes...   My S22 Ultra drops predictably all the way down to 15% and then within a moment or two later it's at 3% or similar and I'm being warned to CHARGE YOUR BATTERY NOW!  Very frustrating.  15% should last at LEAST 20 minutes based on the rate of draining.

I've also noticed, and I'm not sure if it's changed recently too, but the 'basic' charging setting says it charges to 100% and then stops and waits to drop down to 95% before going back up to 100% again.  Why not just hold at 95% then?  Why?  LOL.
