Power Manager

Power Manager is a lightweight and simple application which helps to control your device's power usage. It does so by turning off things like Wifi, Data, Bluetooth, and Auto Sync when your device is off and not being used. Power Manager can be configured to be more aggressive and battery saving or more lax and battery flexible. It can be configured to turn off your device's connections, and leave them off, or to periodically turn settings back on to check for updates to social media and other applications.

On devices running Android Lollipop and higher, Power Manager requires root access to automatically manage Data. On rooted devices Power Manager can also control Airplane Mode.

Power Manager is able to even force Doze mode on Marshmallow and above. This requires a small amount of manual action on the part of the user. See the Doze page in the Power Manager application for more information. May require root on devices above Marshmallow.

Power Manager is small and light on battery and memory. The permissions requested are used entirely to control the device's power usage as advertised.

Power Manager prides itself on:
•  Being simple and easy to use
•  Being open source and actively developed
•  Providing convenient access to device power settings

Power Manager is developed in the open on GitHub at: https://github.com/pyamsoft/power-manager
The entire source code of the application is available. If you know a few things about Android programming and are wanting to help out with development you can do so by creating issue tickets to squash bugs, and propose feature requests for future inclusion.
