Greenify : Improve speed and battery life of your Android device

Today I’ll talk about an app that will help you to improve the speed and battery life of your Android device when you have a lot of concurrently running apps : Greenify.

One of the most common problem experienced by Android‘s users is probably related to lag when the number of installed apps increase.
This issue is not very common when you start to use your smartphone for the first time, but grows over time.
The source of the problem is seldom caused by lack of optimization in the Android OS. In fact, in most cases, it’s just because some of the apps installed are abusing your smartphone resources while running in background.

How often do you see apps running in background even if you are not using it? How often are they not doing anything important for us?

Task killers are one solution, but that is just a stop-gap measure that won’t fix the real problem in the long run.

Android generally keeps apps in memory to make it faster to reopen them at a later date and it clears the memory only when absolutely required.

A task killer would merely temporarily free a bit of memory, but in many situations Android will reopen the apps again after a while.

The process of opening and closing apps is a terrible waste of battery.

The best way to solve the problem is to tell the Android OS not to open that app in the first place by using the “hybernate” flag. That will keep that app completely closed without wasting precious battery life.

That’s where this great application called Greenify comes in, but unfortunately it requires root permissions on your smartphone in order to run.

There are plenty of guides available on the internet about how to gain root permissions for your smartphone, just give a search by specifying your particular smartphone model.

After you install and run the app you’ll see a very simple UI :


Now you can force your apps to “hibernate” by tapping on the + sign and selecting the option from the list.


As you can see Greenify will try to help you understand which apps can possibly create issues by giving you additional details of what the app is doing in background.

The hibernated app can be used normally, but remember that for some particular type of apps this may compromise its normal usage.

For example apps like Facebook Messenger or Hangouts won’t be able to send you notifications at all while hibernated. Remember to choose carefully what to hibernate.

I tried Greenify on my Samsung Galaxy Nexus and I can assure you that it improve a lot the performance and reactivity of the smartphone.


Here the Google Play link to download the app:

    Hello there~I have recently discovered Greenify and i love it. However, I’ve never rooted my phone… I read that Greenify works much better for rooted devices than it will for unrooted, but it will still hibernate apps for you. Is this not true? Because it seems to be working very well for several of my problem apps. But, if it is causing more work for my Moto X than normal, I truly can not tell so far. I’ve had it installed for several weeks. I’ve been struggling with bad battery drain for Quite some time, way before I installed Greenify, but surely do not want to add to That Problem! Any advice would be very appreciated! Thanks also for all your most helpful tips and tricks posts. Loving your site(just discovered it today!) – – also-would u be able to tell me what Greenify Assessibility Dispatcher is? Thanks again…

      you need to have rooted device to use Greenify. It’s useless without root permissions. I’m sorry :(
