I have this issue, COULD be related to the battery issue although mine has gotten much better. I'm getting about 1.75 days with about six hours usage. But, what I DO notice is that after I close an application that uses the GPS like google maps, beatthetraffic, etc, the little icon that indicates GPS use/in use STAYS up in the upper right corner of the menu bar. Even if I go into app manager and kill off those apps (which one should have to do) the icon stays there. I have to go into location services, turn OFF location services completely, then turn it back on and then the arrow icon finally goes away. Is this just some lingering indicator or is this a failure to actually dis-engage the GPS access?
