I charge my S21 Ultra every night on my wireless charger and this morning the phone was charged to 100%. I also had to restart my phone which I thought a bit odd.
I used the phone and waited until the battery charge was below 85% and placed it back on the charger. This time it paused charging at 85%, as it should, since I have the setting under Battery and device care \ Battery \ More battery settings \ Protect battery enabled.
Is this just a one off? Is this a feature and not a bug?
I wish it worked that way for their phones too. So annoying that 50% is not half of my usage time if it starts with 85%. Always have to recalculate in my head.
You can use a bixby routine to to do it.
Just set it to disable battery protection a few minutes before your alarm then re-enable it.
