Greenify

Greenify can help maximize the battery life of your Android phone automatically hibernate background applications so as not to create additional processes or continued operation when you’re not using. You can customize which applications get hibernation and what applications can run out of control, and if you drop $ 3 to support developers, you get the version “donation” that can hibernate system applications as well as user-installed. Not a murderer-that the task is much better than that, and you can add hours of battery life of the patient.
