I was happy with the battery life of my Samsung Galaxy Note 2 smartphone the first couple of weeks. Something changed then however and I noticed that the battery was draining a lot faster than before.
I could not really find out why this was happening but assume that it has either something to do with recent updates to the phone pushed out by Samsung / the phone carrier, caused by apps that I installed on the phone that were running in the background all the time, or by settings that I modified.
There is not a lot that you can do about apps that run in the background, other than to uninstall them if your phone is not rooted. I rooted the Samsung phone recently and discovered the Greenify app afterwards that adds hibernation options to the phone.
Please note: Greenify requires root access to the phone, you cannot use it if you have not rooted the device.
Before we dive into the apps' functionality, we should take a look at what hibernating apps means and why you may want to use this functionality instead of comparable options.
Hibernating apps puts them to sleep so to speak. They won't run background tasks anymore that drain your phone's battery, bandwidth or cpu. What's interesting though, and different from comparable apps, is that they can still be triggered by other apps running on your phone, and that you can still use them normally if you open them on the device. So, you get the apps full functionality when you decide to run it.
The app itself is easy to use. It displays a list of apps that may slow down your system when they are running in the background or when they are active. To hibernate any app here, tap on it and then on the checkmark at the top. You can tap on multiple apps at once to hibernate them all in one operation.
A tap on show more apps displays all installed apps on the phone so that you can hibernate those apps as well on the device.
