Battery Notification

Battery Notification is a free and open-source Chrome extension that provides a persistent notification displaying detailed battery information at a glance. It shows the current battery level with color indicators (for Android 5.0+), battery temperature in Fahrenheit or Celsius, charging state, battery health, and charging/discharging amperage. Advanced users with root or ADB access can also see the estimated time remaining until the battery is fully charged or discharged. The extension runs a foreground service to instantly update this notification whenever battery status changes, ensuring you always have up-to-date information.

Designed to be lightweight and privacy-focused, Battery Notification requires minimal permissions only necessary to monitor battery stats and to restart after device reboot. The extension contains no ads or in-app purchases, emphasizing user trust and transparency. Source code is publicly available on GitHub, inviting collaboration and inspection. Battery Notification is ideal for users who want constant access to detailed battery data without opening settings or other apps.
