Okay, I enabled location services for Passbook for the Starbucks and Fandango apps, but they're killing my battery. How do I turn this off so my phone isn't constantly checking to see if I'm at Starbucks?
Try looking under Settings > Privacy > Location Services and switch Passbook off. If that doesn't do it, go into Passbook and flip your passes around by tapping the "i" and switch "Show on Lock Screen" off.
