Black Screen of Life is a free Android utility that helps you save battery life by turning off the screen while you listen to videos. Developed by Lifecoder, this app offers a simple solution to a common problem. With Black Screen of Life, you can turn off your phone screen and still enjoy your videos without draining your battery. This app is available in the Utilities & Tools category and is easy to use.

The app offers two main features: starting and stopping the service by clicking on the button, and selecting vibration and sound to identify whether the service is running or not. To use the app, simply click on the start button, and then place your phone on the table with the screen side facing down. The screen will automatically turn off, and you can enjoy your videos without any interruption. It is worth noting that you should not click the mobile screen off button, as this will stop the video by the system.
