Add this app to your lists
Hibernate is a small utility which allows you to hibernate selected background processes. It "kills" them by means of "killBackgroundProcesses" used internally by Android to free up resources. This method differs from killing applications in the system list of running processes in the way, that it allows applications to save their state before exit, so when you return to the hibernated process back, it will be restored to its previous state.

The utility can be usefull for developers who need to test how their applications behave while being unloaded and re-loaded by the system, as well as for other users searching for a way of system optimization on-the-fly.

THIS IS NOT A TASK KILLER. The app does actually freeze selected tasks, unloading them from operating memory and preventing further CPU usage, BUT the tasks remain in the system list of "running" tasks. According to Android documentation (citation): "Note that "running" does not mean any of the task's code is currently loaded or activity -- the task may have been frozen by the system, so that it can be restarted in its previous state when next brought to the foreground." And this is the Hibernate who instructs the system to freeze selected tasks. Please, note that you may see the button "Force stop" still enabled in the "App info" system dialog for hibernated tasks. This is because they are frozen, not removed. Unlike to the hibernation, the "stopping" does forcedly and completely destroy the app. This makes a big difference.

The app DOES NOT REQUIRE rooting you device. It is designed to work without SuperUser privileges.

The app supports a service mode allowing for automatic background hibernating of specified processes. Attention: use the service mode with a caution. If some of hibernated processes are recreated constantly by themselves, the service may exhaust the battery.

The service is configured in the settings dialog. Among other things you can enable or disable service notifications about varios events.

Use the Status dialog to edit the list of currently hibernated processes.

If you think you found a bug, please contact me via e-mail and provide as many details as possible. There exist too many different devices and Android flavours, so I can't test the app on all of them. We could try to solve your specific problems together, instead of dumb downvoting of tha app.

WARNING! It is strongly recommended to not hibernate apps which are installed as widgets on your launcher or lock screen.

Recently changed in this version

Added a handler for Android's system exception "Package manager has died", which may occur on devices where the list of installed apps is too long. This is a limitation of Android! In such cases Hibernate will show the error message instead of the lists. You can solve the problem by removing some unneeded apps and then kill and start Hibernate again.

    The App is great. Gives me decent amount of free ram by hibernating apps, whilst not drinking battery. I am impressed. But one issue, it uses up to 40MB ram. For such a small app, that is still a lot of RAM. Please drop it to less than 20. That will work wonders. Plus, try to add a feature where for a particular app I select, I can assign infinite hibernation to it, so that it is never using memor

    Compared to greenify, hibernate blows greenify out of the water, on my s3 running cm11 which is a battery hog I get 0.3% an hour drain, fantastic work devs.... A+++

    Too bad the app need the battery resources power to make it run always, otherwise it can't auto hibernate without it ... should be great without draining battery power
