Modern Android smartphones and tablets pack powerful hardware. They have a multi-core GPU, CPU, and a decent battery. They flaunt an HD, 1080p or a WVGA display. The handsets include WiFi, 3G, Bluetooth and two cameras. As the hardware in mobile devices is powerful, the battery that supplies power to it will drain faster.

To save power, the screen of the Android, Windows or IOS phone will automatically turn off after a few seconds. But this feature doesn’t guarantee that your phone’s battery life will be great. Some heavy apps might run in the background, and they’ll keep using the hardware which in turn, wastes the battery power.

To prevent this situation or to find and kill such apps, download any of the below top Android battery saver applications and use it. These apps will help you in saving every unit of power on your mobile device.
