Once you have added, your apps leave the rest of the thins to Greenify. Just start the app, provide root permission, and add apps that you want to hibernate. It will mute all the notifications sent by apps added in the Greenify. Instead of always running in the background, these apps are put on sleep and will only be awake once you manually start them. Greenify pause or hibernates the apps which are not much used. This application is just a beast when it comes to saving the battery of your android device. It is a straightforward and lightweight application but with a lot of features.
