The AirBattery app is a helpful tool for Android users who own AirPods (1, 2, 3), AirPods Pro, or Powerbeats Pro. The app provides a battery level indicator that displays the AirPods' battery level in a popup window with animation, as well as in the notification bar. The app also features ear detection, which suspends and resumes playback after AirPods are plugged or unplugged. Additionally, the app allows users to invoke their voice assistant by tapping on their AirPods four times.

To use the app, users must give it permission to access their location for Bluetooth LE discovery and to display window overlays for the popup. Once permissions are granted, users can select their desired options and enable the service. It is important to note that the voice assistant triggering feature only works when nothing is playing in the background due to Android limitations.

If users experience any issues with battery level refresh, they can add the app to their phone's battery optimization settings white list. Any suggestions or bug reports can be sent to the developer at [email protected] .

Overall, the AirBattery app is a useful tool for Android users who want to monitor their AirPods' battery levels and enjoy additional features such as ear detection and voice assistant triggering.
