3C Battery Stats
This app allows gathering (the legacy) 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.
I cannot provide further help or instruction as it will be considered a Play Store violation: Apps that provide instructions on how to hack services, software or hardware, or circumvent security protections).
