About this app

Featured as Lifehacker's Top 1 Utility in 2013 Best Android Apps (http://goo.gl/1VMwnE), Android Authority's Top 3 Best Root Apps (http://goo.gl/g0L0qZ).

"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 (http://goo.gl/ZuLDnE) or G+ community (http://goo.gl/MoszF).

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.

=== 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.

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

=== 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!

Used to be the BEST, but unfortunately it has not been working smoothly since Android 12 on OnePlus devices. I have both the 8T and 10T and experience the same issue. When selecting any apps to hibernate/force stop, greenify constantly stutters and cannot execute consecutively. I used to hibernate 10-20 apps within 10-15 seconds, but now it takes as long as 1-2 minutes for all apps to hibernate. Please fix! I've used greenify for over 5 years and this is the worst performance issue I've seen.

I've used this app partially before as an add on for an F-Droid Island type app that it was compatible with way back when. Then it worked relatively well, for a non-profit phone. Now (and I mostly blame Chromebook system for this) it doesn't really do much of anything. I can't give it any required permissions, like default Assist app, bc the app crashes. It also does not even list system apps anymore. Without Island, which isn't compatible with Chromebook, it can't really do anything.

A lot of apps that claim to "tune up" your cell phone do nothing except display advertisements. Not so with Greenify. Not only are there no advertisements, the app actually works. I was having a problem with too many apps running in the background and using ram memory, slowing down my phone. I uninstalled some of the apps, but Greenify help control the apps I did not want to get rid of. Apps have stopped working on their own; I have more memory, and the phone is smooth. I will buy this app.

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.
