App summary

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 ===

If you are an android user, and didn't know already, when you restart your phone, countless apps try to resume and many open on their own. Most of the time they never resume correctly, and can noticably slow any user experience. The fact a business like oasisfeng created something at such a quality to reverse this is amazing. Thank u!!

No longer works with Android 9-14 even though it says it is does. Once I had switched to a newer phone, the donation package is no longer compatible. No new updates since 2019... Have to force every app to close manually and it still fights me to close apps. Unfortunately no one has made anything similar to this app. It really needs to be updated and reworked for the newer phones.

Excellent app, but agree with others that it probably is in need of an update. Borks after a while and needs resetting in Accessibility Services (hopefully can be addressed in a future update), but other than that, it's the best of the app closure devices. And though I probably didn't need it, I upgraded to premium, if for nothing else, to show some love to the developer. Recommended. Update: abandonware?
