Battery Doctor - Phone Faster and Cleaner is a battery-saving utility that helps you keep your Android phone's battery health from draining too fast. It monitors and analyzes the current battery level, and helps you to extend your phone's battery life by closing battery-draining apps and processes.

The Battery Doctor app also includes a Junk Cleaner that will help you free up some storage space by removing junk files, and a Device Speedup that can speed up your device by freeing up memory and resources.

Additionally, the app provides an Apps Manager that allows you to manage your apps, such as install, uninstall, and status. It can also help you quickly perform functions such as turn on/off the internet, bluetooth, synchronization function, location, airplane mode, do not disturb mode, and so on, to save energy for your phone.
