Batter will take extremely long to charge passed 80%. It will charge fine and once it hits 80% it will stay that way for an extremely long time, up to half an hour-45 minutes. Other times it will charge just fine passed80 tested on different cables etc. No 80% charging enabled.
I like to limit it to 80% when I charge my phone over night, and then charge it to 100% in the morning while I’m chilling around the house. I’ve had this happen a few times, where even if I take it off optimized charging or the 80% limit, it refuses to charge past 80%.
I just have to unplug it and replug it a couple times to get it going. It seems like a bug.
