Charger Alert (Battery Health) v3.0 build 14

Do you want to protect your Android device & battery health? Then use Charger Alert™ - the battery saver app that helps extend your battery life and prolong your battery health by alerting you when the battery percentage is too low, the temperature is too hot and overheating, or your device has finished charging so you can unplug it.
Charger Alert can also warn you with an alarm if somebody unplugs your mobile phone or device from the battery charger, or if there is a power outage while it is connected and charging.
You can use Charger Alert to always show the battery percentage remaining and charging status as a notification in the status bar, on your lock screen, and as a home screen battery widget.
