The Greenify application sounds more like something to do with drugs, or hippies — or at the very least, the environment. In actual fact, the Greenify app makes your device ‘greener’ by allowing you to find out which apps are taking away your battery life and performance so you can eliminate those from your list.
You can use the Greenify app to check which apps are running in the background, which apps are waking up your device, which apps are running and for how long they run. With this, you can choose to hibernate apps, so they stop running in the background. You might like the apps and wish to still have them on your device. Greenify allows you to do that and just hibernate them instead of deleting them all together. It’s a great app that is incredibly powerful once you work out how to use it to its fullest potential.
