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 ===

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.

It's the most essential app I've used for every phone using Android. I have no idea if it's available for Apple, don't care. This app will keep your battery and phone speed at optimal levels with the push of one button, all those installed apps that start themselves, along with others, for example Amazon, that slows your phone down or bogs down your data stream, this will chill out those annoying apps. You can set it up to avoid whatever app your using from stopping and pick every app to drop.

My number 1 most used app over the decade. No ads. Useful for Android devices that have low RAM. Had issues with apps unable to multitask in the background due to lack of RAM which also results in lag. Much faster than manually force closing apps. Hope Google doesn't take it down & prohibits it in the future. App has had issues with more recent Android OS (Android 10 & above) such as accessibility services needing to "restart" or the app being auto hibernated by Android after a period of time.

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.
