Auto-start Manager provides a smart way to optimize the system of your device while saving its battery power. When you noticed that your system becomes slow in responding to your commands because of some apps running on the background, you can disable them with one swipe of your finger.
Launch Auto-start Manager.
Select the apps that you want to prevent from starting automatically, then slide the Allow button to the left.
When notification pop-up appears, tap Deny to cancel the app from automatically starting.
