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 (goo.gl/ZuLDnE) or G+ community (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.

Fixed "Hibernate and Sleep" shortcut when only apps in Island are pending.
