Battery Alarm - Charge Alert

Battery Alarm - Charge Alert helps protect your battery by signaling you when it reaches a chosen charge level. You can create alarms at common thresholds (20%, 40%, 50%, 80%, 100%) and receive a reminder to unplug. The alert runs in the background, even with the display off, so you can charge safely without watching the screen.

Premium features unlock when you subscribe: no ads, a fade-in volume that starts softly, and an auto-stop alarm that ends once you unplug the charger. The extension is free to use, with optional upgrades for extra convenience.
