Battery Sound Alarm

Battery Sound Alarm notifies you with music when your device reaches a full charge, so you never leave it plugged in longer than needed.

Set up takes seconds. Choose your notification song from your device's ringtone library, connect your charging cable, and step away — the app runs silently in the background. The moment charging completes, your selected music plays automatically. Disconnect the cable or close the notification to stop the alert, and you're done.

Customize every aspect to fit your routine. Adjust the alert volume, enable vibration feedback, and set a battery level threshold — the app can notify you at 80%, 90%, or full capacity depending on your preference. Use the Do Not Disturb setting to silence notifications during specific hours, and the app intelligently switches to push notifications if earphones are connected, so the alert reaches you without blasting audio through speakers.

Stay informed at a glance with the battery level display widget that appears at the top of your screen throughout the day. Track your charging patterns with the built-in battery charge history, which logs when and how often you charge. A low battery alert warns you before your device runs critically low, and real-time battery status updates keep you aware of your device's power state.

The 4x1 battery widget brings charging information directly to your home screen, giving you instant access without opening the app. If you use earphones regularly, the app detects them and switches to silent push notifications so you stay aware without disturbing those around you.

If Battery Sound Alarm doesn't work on your first try, the built-in troubleshooting menu offers a one-tap fix that adjusts your phone's settings automatically. The app accesses your storage only to let you search for and select music files as reminders — no other permissions required. On some devices, you may need to run the app once while charging to initialize it properly, then it works entirely in the background going forward.
