Black Screen Mode

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.
