For the past week, my iPhone 4 has constantly been tracking my location, or at least it says it has been. It's been causing a dramatic drain increase in my battery also. I can't figure out what is causing it! I've closed every single app and restarted my phone several times. No matter what I do, I can't get the little GPS icon in the corner to go away. Has this happened to anyone else? If so, what'd you do to stop it? I know I could try turning off location services, but I use them a LOT, so that'd just be more inconvenient than the battery drain.
