So at 99% I plugged in my phone and noticed that the battery usage went to 0 mins. Is that normal? I swear that should happen when it hits 100%? I have this paranoia
Just like at the lower battery charge range, at the higher end the battery percentage estimates can be slightly less exact than typical, so battery usage gets reset even at slightly lower percentages too, as far down as 97% if not even 95%. It's normal.
