About this app

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 actively using them, to stop them from lagging your device or 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.

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 the hibernation procedure.

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 background running services for auto-hibernation to work. It is designed and implemented in extremely lightweight and nearly zero CPU and battery consumption.


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.

This app uses Accessibility services, to automate the hibernation procedure.

=== FAQ ===

This was my go-to app for a long time for turning apps off that didn't need to be running. Unfortunately it is rather buggy after upgrading phones and having newer operating systems going simply because this app has not been updated in years. For the love of Mercy please update this app to work better with newer operating systems so that this can continue to be my go-to app. I am quite sure many other people will agree with me on this one. Otherwise amazing work.

Not very good. Why? Sure it saves battery and all and made my bat life go up by 2 or so hours but with me it has a tendency to turn my screentime down to below the minimum setting on my phone, and on top of that when i try to turn the screen back on it does for almost half a second then shuts back off, and repeats like three times. I regularly have to turn the screen back on by pressing the power button almost 10 times, because it shuts off on me that much. Like every 5 mins. Good app.

Update to review: I have had this app since long before there was ads to watch. Now I can't get away from them. Now there is 2 Greenify on my phone (note20ultra) and neither of them work. I have friends who I recommend this app to going, hey what's going on, to me. I am amazed at how badly this wonderful service went so wrong. I have been using Greenify for years now. I have maintained Greenify on every device both I have and now husband.

What's new

NEW: Restrict the ability of selected app to run as foreground, to transform it to background-free. For non-root device, it requires Island with God mode activated. (Android 9+)
Wake-up tracker and cut-off now works for apps in Island and compatible with Android 10.
App analyzer is improved with foreground service detection and other minor tweaks.
Fixed "Hibernate and Sleep" shortcut when only apps in Island are pending.
