A closer look at the app
An 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. The accuracy and availability of battery health metrics depend on your Android device and the information its OS provides — Battery Inspector offers diagnostic indicators, not a guarantee every fault can be detected.
