Simple.

Just run this app by touching it's notification.

It will save your battery when you want to listen just a music from a video or play a game in auto mode.

Without this app you will spend about 40% battery more than normal just for unnecessary screen use.


Options (I recommend you to use)

- Disable touch : It will disable touch event to prevent unwanted touch.
- Double tab : You can finish Black Screen Mode by tapping the screen twice.
