This question already has an answer here:

My phone (Note3) has a large amount of ram, but there are always lots of applications that can run back ground which can easily consume more than 90% of your memory.

It's really annoying to manually clean them time to time.

Can I set it up so that if I click home button then I will end current app completely?

This question came from our site for computer enthusiasts and power users.

  • Cyanogen (and probably other custom ROMs) have settings where pressing a button -- such as the back arrow for a couple seconds -- will completely close an app. – That Brazilian Guy Mar 28 '15 at 10:42

No, there's no setting to fully close an application when you press the home. It depends on how the program is built. Some stay running, some stay in memory but are inactive (not eating CPU but wasting memory in case you restart the program), and some just close as desired. Additionally, there are plenty of Samsung or carrier applications that run in the background full time and don't have an onscreen program to open or close.

There are several applications on the Google Play Marketplace that will automatically close all applications for you either on a schedule or on demand, but that's as close as it gets unfortunately.

Perhaps there are more technical answers that involve custom ROM's, but that's not applicable within the confines of a SU question/answer.
