Featured as Lifehacker's Top 1 Utility in 2013 Best Android Apps (, Android Authority's Top 3 Best Root Apps ( NEW: "Aggressive Doze"and "Doze on the Go"to maximize the battery saving on Android 6+, even without root! (details explained in settings) Never should your phone or tablet become slower and battery hungrier after lots of apps installed. With Greenify, your device can run almost as smoothly and lastingly as it did the first day you had it! Greenify help you identify and put the misbehaving apps into hibernation when you are not using them, to stop them from lagging your device and leeching the battery, in a unique way! They can do nothing without explicit launch by you or other apps, while still preserving full functionality when running in foreground, similar to iOS apps! Please report bugs in the XDA forum ( or G+ community ( Greenify NEVER EVER collects your personal data despite the capability of accessibility service, it just takes advantage of it to automate things. IMPORTANT: Greenifying an app implies that you are aware that all the background functionality (service, periodic task, event receiver, alarm, widget update, push message) of this app will become out of service during the hibernation except when you are using this app. NEVER greenify alarm clock apps, instant messaging apps unless you don't rely on them. Please do verify the impact of greenified apps on which you heavily rely. Note: Greenify does need a background running service for auto-hibernation to work. It is designed and implemented in extremely lightweight, with an average RAM footprint less than 5M, and nearly zero CPU and battery consumption. === PERMISSIONS === DEVICE ADMIN: To turn off the screen immediately after automated hibernation on non-root devices. DRAW OVER OTHER APP: To show guide layer over the app setting UI of system on non-root devices. DISABLE SCREEN LOCK & BIND ACCESSIBILITY SERVICE: For automatic hibernation to work on non-root devices.
