SuperFrezZ is an Open Source Application which helps in killing the background running app of the Smartphone. It is a great alternative for "Greenify" (closed source)

Applicable in Android 4 version and above, the app kills the unnecessary running apps and enhance the battery and phone life.

The app can be downloaded from F-Droid website. Some of the main features of using the app are

• it is completelly open source and free to use
• there is an option to close the apps which were not been used since long.

A good option to make your phone work faster rather than upgrading your Android to put more background restrictions.
