3C Battery Stats
This app allows gathering (the very old) battery statistics, which shows apps keeping device awake while not charging. It can be used by 3C Toolbox and 3C Battery Monitor on Android 9 and above to display those statistics.
For that app to work, it needs to be granted BATTERY_STATS permission, otherwise it is useless and will not display anything.
- If your device is rooted, grant root to the app and let it do that for you.
- If your device is not rooted, you need a PC and knowledge of installing and using ADB.
Running that command from the PC will enable the app features: adb shell pm grant ccc71.bs android.permission.BATTERY_STATS
