Since I've updated to Google Maps 4.2.0 I've noticed that the program is using up a large part of my battery. Is anyone else seeing this? For example, my phone has been off the charger for 3 hours and the battery use says 36% for Maps. I'm down to 70% battery life. GPS is turned off and am not using latitude. I haven't even used it since I unplugged my phone. Before the update, Maps wouldn't even show up if I hadn't used it.
