    "Your device... like the first day"

    Greenify is a popular utility app which helps techies and avid mobile users keep their devices fast and clean even when they have lots of apps installed.

    What is this application great for? Improving your battery life, memory usage and increasing your device speed. In addition, the developers state that if you have a rooted device, you won't have to worry about any of that.

    How does it work? Greenify shows you which are the apps that can cause a slow performance and allows you to stop them and feel like your device quickly works better than before.

    OASIS FENG is the developer of Greenify and the Donation version of the app. Don't accidentally put your Alarm clock to hibernate... as you might not wake up at the right time!

    Useful and easy to use, simple design.

    Featured as Lifehacker's Top 1 Utility in 2013 Best Android Apps (, Android Authority's Top 3 Best Root Apps (

    "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: This app uses administrator privilege to turn off the screen immediately after automated hibernation on non-root devices. This permission will be requested explicitly for your consent only if required.
    DRAW OVER OTHER APP: To dim the screen during automatic hibernation when the screen is expected to be off.
    DISABLE SCREEN LOCK & BIND ACCESSIBILITY SERVICE: For automatic hibernation to work on non-root devices.
    GET ACCOUNTS & WRITE SYNC SETTINGS: Control the account sync of apps if its sync task is too frequent.

    === FAQ ===

    * It seems that automatic hibernation is not working.
    * Some of my greenified apps (e.g. Google Maps) seems not hibernating.
    * I want to greenify system apps!
    * De-greenified apps still got no push notification!

    No bloatware or the google weather app that keeps giving a crash message on my Verizon S7 are in the app list. These apps may be in the Donate Version since they may be a "system app," but I'm not going to donate just to find out. Developer should show all the "system apps" in the free version, but have them greyed out until you donate.
