I just wonder why OCD starts acting up if somethings are running in the background? Even on a computer you have things running all the time that you don't see. Now if a specific app is causing problems then that needs to be delt with. Like I said try Watch Dog it will tell you if any app is eating more cpu then it should and ask you want you want to do with it by freezing,force stopping and you can decide if you want to uninstall it because its not worth it.
