How do I stop Android Apps from running in background with Samsung Galaxy S3?

[Cincy Myrtle]

Each time i start my cell phone, i have a ton of apps automatically running in the background.
(facebook, camera360, weatherunderground, etc)
I havent even opened these apps up yet, and they are active and running.
I go to each active running app, then hit STOP, but mins later it will start back up.

I made sure all notifications on each app were turned off, but it didnt help any.

Is it normal for all the apps just to keep running like that at startup? I think its draining my battery life. Maybe i should just delete the apps so that i dont have to buy spare batteries.

Hold down the home button and swipe away the apps
