Hi! When I am in an app and hit the "home" button to go back to the main home screen, does the app I was in close or is it still running in the background? I just hit the home button for a second and move on to another one. Should I be doing something different? I don't want to waste battery life by having several apps running that I'm not using anymore. Does this make sense? Any help is appreciated. Thanks and I'm sorry if this has been answered already!
