If ABattery is useful on your device, star the repository to help more Android users discover it.
Android exposes useful battery data across several APIs and device-specific system files. ABattery brings the available signals into one readable Material 3 dashboard, while clearly marking values that are estimated or unavailable.
- Real-time battery level, charge status, temperature, voltage, current, and power
- Reported or best-effort cycle count with estimated values clearly marked
- Design capacity and full-charge capacity when the device exposes them
- Live current chart for charging and discharging behavior
- Light, dark, and system themes
- 16 languages
- No ads, analytics, account, or Internet permission
- No runtime permission prompts
Battery reporting varies significantly between Android versions and manufacturers. ABattery reads data from Android's battery APIs first, then uses available system information and local estimation as fallbacks.
Some devices hide capacity, cycle count, or charging limits. In those cases ABattery shows N/A instead of inventing a value. The app is a diagnostic tool, not a laboratory measurement or a replacement for manufacturer service tools.
Community reports currently confirm the app running on devices including the Google Pixel 7 with Android 17, Google Pixel 6a with GrapheneOS, and LG V40 with Android 10. See the community-tested device list for details.
If a field behaves differently on your device, please open a device compatibility report with the phone model and Android version.
- Android Studio with Android SDK 36
- JDK 17
- Android 8.0 (API 26) or newer for the target device
