I think AGG runs in the background because there's no "quit app" button, and spamming the back button on Samsung Galaxy phones will just give you the "Cannot go back" message. So the only way to close the app on normal phones is to minimize it by pressing the centre button, and wait for it to close itself.

Try getting a task killer or battery management app. If your phone is rooted, use Greenify. I'm using a custom ROM on a Samsung Galaxy SIII so i can just long press the back button and it immediately kills the current app - saves a ton of battery, I swear.
