Greenify help you identify and put the bad behaving apps into hibernation when you are not using them, stop them from battery leeching, memory hogging and stealthy running, in an elegant and unique way! They could do nothing without your explicit launch, while still have full functionality when running in foreground. Like what iOS apps act!
The built-in App Analyzer will analyze and show apps in your device that keep running persistent services and those launch itself automatically on a regular basis (when network connectivity changes, or every time you unlock your device, install / uninstall / update your apps, etc).
NEW: Non-root working mode is now supported in 2.0+, but still in early stage. It currently lacks auto-hibernation due to privilege restriction. Use "Hibernate All" shortcut (widget) for convenience. On Android 4.1+, an accessibility service can be activated to automate the manual hibernation procedure.
Compared to other popular tools aimed for the similar purpose, Greenify give you the unique experience:
◆ Unlike the "Freeze" feature in "TitaniumBackup Pro" that totally disable your app, you can still use your app as usual, share content with it, without major uncomfortable impact on user experience. Greenify is nearly transparent! Set and forget~
◆ Unlike "App Quarantine", you can launch greenified apps in any way as usual. No more crafted app-launch widgets, no more manual disabling.
◆ Unlike "Autostarts", you can benefit almost all its advantages, but never need to deal with the complexity and risk of obscurely named app components, and never lose functionality when app is actively running.
◆ Unlike any "XXX Task Killer", your device never fall into the cat-mouse-game of stealthy-running and aggressive killing, which unnecessarily consumes much battery juice. Since all greenified apps will be put into hibernation until the next time you launch them, there is no need to "kill" them during the hibernation.
As the bottom line, Greenify do need a background persistent "Cleaner" service to put the greenified apps back into hibernation when you are not actively using them. It is designed and implemented in extremely light-weight, with an average RAM footprint at 2M in total, and nearly zero CPU and battery consumption.
IMPORTANT: Greenifying an app implies that you are aware that all the background functionality of this app will become out of service during the hibernation except when you are using this app. The background functionality includes but not limited to:
* Persistent background services
* Broadcast receivers, which respond to global device events, such as network state change, SMS reception.
* Alarms, which activate background task at specific time or interval.
* Widget update. Widget should display but never update because periodic update involves background task.
* Push messages. Push is also disabled since it would activate background task on Android, unlike iOS which just shows up messages to user.
Please DO NOT greenify alarm clock apps, instant messaging apps unless you never rely on them. Please be sure to verify the impact of greenified apps on which you heavily relies.
Thanks for the help from community volunteers, Greenify is translated into more than 10 languages, and still expanding to more.
If you are willing to help us, you can either improve the current translations, or contact me (by Email) to add translation languages to start new translation.
