For most people, this is an old tune, one to which they have danced before: the eternal promise of extending battery life, making your device smooth and silky as the time it was taken out of the box. We have had these programs such as task managers, app killers, RAM savers, and so on for a very long time. The truth of the matter is that Android is actually quite capable of handling apps in a very efficient manner, and more often than not, these are not normally needed. Also, the available RAM on most newer devices certainly makes them obsolete (for newer gen devices anyways). Furthermore, leaving programs in RAM (when available) prevents the need to relaunch them the next time you open them. However, when a new approach is tested, it is always worth looking into it, and that happens to be the case with Greenify by XDA Forum Member oasisfeng.
The app itself acts like a bit of a task killer, hunting down applications that may be active in memory but not being used. This app, however, uses a different method to kill an app. The method used here not only disables the apps, but it prevents it from coming back to life, which is the failing point of most app killers. There are other ways to achieve a similar result, such as using the freezing feature of Titanium Backup, which essentially completely disables the app temporarily. However, using this approach also disables your ability to use said app. Greenify uses a method known as am force-stop pkgname as opposed to the commonly used kill. The app hunts for alarms and active ServiceRecords, which act as restore points for the app being killed and gets rid of them. This way, the app is completely disabled without actually completely disabling the app.
The app requires root, but other than that, it has no special requirements. Please take it for a spin and make sure that you leave some feedback for the dev. Also, please leave your experience as well. Did it help? We would love to know.
No more envy of your friends’ iPhone which never become slow and battery hungry after lots of apps installed. With Greenify, your Android device can also run almost as smooth and lasting as the first day you have it!
