Charger Alert is a useful utility for Android devices that can alert you when your device is connected to a charger, or when the battery is low, or when the device has been fully charged.

There is no need to have root access to use this app, and you can also use it to display information in the status bar, on the lock screen, and as a widget in the home screen.

The information that you will see includes the current battery level, the percentage remaining, the battery temperature, and the time that the device has been connected to the charger.

If you have root access, you can also enable or disable the alerts.
