Battery lite

If you've ever asked a question about the kind of battery your smartphone contains, apps like Battery lite can provide various details about your battery status.

Battery lite consists of a single main screen with a complete log of your Android device's battery status. You'll have your battery capacity, temperature, remaining charge, and voltage.

On the other hand, you've got the option to program a notification so you get a popup when your smartphone temperature is abnormal or when your battery charge is getting low.

In short, Battery lite is a simple and interesting app to monitor and manage your device's energy use.
