HONEST BATTERY CHECKER
Battery Inspector measures battery data from your phone and estimates battery health from real charging sessions. Accuracy improves after a few charges. It does not repair, calibrate or extend your battery, and makes no fake "battery booster" claims.

Note: The accuracy and availability of battery health metrics depend on the Android device and the information provided by its operating system. The app provides diagnostic indicators, not a guarantee that every battery fault can be detected.
