Battery Saver is a free battery-saving utility that helps you to monitor the status of your phone’s battery and extend its usage time. It’s one of the best battery-saving tools on the Android market. 

It allows you to do all that by simply using the built-in hardware sensor and reporting the battery’s status and power consumption to the app. You can turn off apps that drain power or cause your device to overheat by using the built-in optimizer. 

The app can also help you clean up the junk files and system logs that often accumulate as your device ages. By using the built-in optimizer, it will help you keep your device running smoothly and help you enjoy a longer usage time.
