ShutApp helps you close all the apps that are running in the background so they stop wasting your smartphone battery and bandwidth. With just one click, all those apps will be closed in a matter of seconds. The best part is that the apps that are shut down remain that way until you open them up again.
From the drop down menu located at the left side of the screen, you can configure your blank list. All the apps in this blank list won’t be closed when you click on the ShutApp button, which personalizes your experience even more.
According to the developers, ShutApp is ‘truly a battery saving app’... and it really is. Depending on the number of apps that are usually running on the background, one tap in ShutApp gives you quite a few minutes of battery life.

This App is Highly Recommended
Excellent, but... After updating the phone to a new MIUI version, the app stopped working. It needs to be fixed urgently!!!!!!!!!
