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 using them, to stop them from lagging your device and leeching the battery, in an unique way! They can do nothing without explicit launch by you or other apps, while still preserving full functionality when running in foreground, similar to iOS apps!
Non-root working mode is now supported in 2.0+, but still in early stage. It currently lacks auto-hibernation due to privilege restriction. Try “Hibernate All” shortcut (widget) for convenience. On Android 4.1+, an accessibility service can be activated to automate this manual procedure, thus eliminate all the clicks.
Greenify NEVER EVER collects your personal data despite the capability of accessibility service, it just takes advantage of it to automate things.
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.
