tl;dr - I have two Galaxies that think they're draining very quickly but may not be.
This is happening with both my own Galaxy S7 and my wife's S6. It seems to lose power very quickly and shut down when it hit's 0% battery. When plugged into a charger it reports a reasonable time to recharge (~2 hours) but then charges much faster, as though it actually had as much battery left as it should, but the reported percentage was wrong. Sometimes, when leaving it on a charger overnight, it apparently shuts off the charging when it hits 100%, then drains down to zero by the time I wake up. Then I plug it in and it charges quickly.
I talked to a cellphone repair guy who said it may be a software issue and that a factory reset may fix it. The fact that I've run both phones in Safe Mode for a few days and they behave fairly normally makes me think it's a software, not hardware, issue.
I searched all over for info on this but all I find is how to reduce drain, not how to fix software-related misreporting/misunderstanding of remaining battery power. Is this common? Can anyone shed any light? I'm about to bite the bullet and do a factory reset.
TIA
