Battery Doctor is an app that monitors your Android's battery, helping you adjust various apps and settings to make your battery last as long as possible.
Optimize your battery
With Battery Doctor, you can get detailed information about the remaining percentage and subsequent time you have left before your battery dies, as well as how much time you can spend using each app before your battery drains. If you want to use YouTube, for example, you'll be able to use if for much less time than if you're planning to make a phone call. It'll also show you what to turn off to extend your battery, including Wifi, GPS, and screen brightness.
One of the best features of the app is that it tell yous exactly how much battery power each app you have installed is using, separated into categories by the apps that are currently running, apps that aren't running, and system apps. By clicking on Save Power under Save, you can see a list of the apps that use up the most battery power, with the option to close them directly from the app.
If you run Battery Doctor while you're charging your phone, you can get a history of you're phone's daily charges to see if your battery health is improving.
You can even get a bit more advanced and check the CPU, hard disk, and memory usage on your phone, although the accuracy of memory usage isn't always reliable.
Battery Doctor is super easy to navigate. All the options are really clear, and playing around with it for just a few minutes will tell you almost everything you need to know about using the app. The interface is really clean, and its pretty easy to find what you're looking for.
There are different menu options at the bottom of the screen including Save, Charge, Mode, and Rank, where you can access all of the different utilities of the app. The Android version even has a widget for your home screen so that you can quickly adjust any settings to make your battery last longer.
