Battery Monitor processes battery and device information locally, including values exposed by the device such as a battery serial number. It does not transmit this information or collect it on external servers.
This project is a fork of Battery Indicator Pro / BatteryBot Pro, with continued development and rebranding.
The main goal of the fork is to maintain and enhance the app to ensure it works well on modern Android versions. Check CHANGELOG for details on changes and updates.
