Battery Doctor (Battery Saver)

Despite Battery Doctor by Cheetah Mobile Inc. being the most downloaded app on the Play Store, we have decided to put it at the bottom of our list after all other applications.
We have several reasons why we have decided to do this. The first is that apps by Cheetah Mobile are notorious for being quite resource-heavy themselves, running in the background and pushing all kinds of notifications to your device. Another is that the app uses only a superficial means to extend your battery life like killing background processes and encouraging you to disable various things like Bluetooth, WiFi, data, etc. The app itself is not open source which may be an issue with some people.
But despite all of this, Battery Doctor has still a plenty to offer. The task killer work fine, the app accurately displays remaining battery and charging time, you can schedule power saving mode for work/class/sleep, and it even gives you an useful charging tips. And there is definitely no denying that the app looks pretty good.
