There is a useful feature: battery protection.
When i turn it on, the charging stops at 85% apparently but the battery drops quite faster than while it is turned off. It seems like the phone stops charging at 70s%, not 85%!
For example, when battery protection is off, I complete the day with 40-50% but when it is on I have only 10-15% at the end of the day.
I suggest that the user can change the battery percent that charging will be stopped at. Say, 85% 90%, 95%. Thereby, the user can protect the battery and achieve longer usage at the same time.
