Hi, I have seen others reporting the same issue on XDA and Discord. After 6.1, the only option that works for Battery Protection is Maxium which takes the phone to 80% then stops. Using Basic or the other option is NOT working correctly. Basic it is supposed to charge to 100% then let it drop to 95% before it charges again but it does not..it keeps it at 100% no matter what intense activity you are doing on the phone. Hopefully this gets fixed quickly
