Yeah all my apps are closed. I even deleted the google app before I restored the phone and it wouldn't go away. I'm restoring the phone but seems it installed iTunes version of 7.1 so maybe it will fix if not I can live with it I guess unles it doesn't effect battery
Any apps that constantly use your location (such as nike+ move) and have background app refresh turned on will do this, even if you close them out in the multitasking tray.
Open Settings, Privacy, and Location Services. See which apps have purple arrows next to them to identify the culprit.
