"Maps" would be the Google Maps app. It's possible you have the option set that finds your location for Google searching. Maybe that is constantly trying to find your position via GPS. If it cannot find a position, it'll keep trying...? I'm not 100% sure, but its just a thought.

 

Well, from what I understand, if the GPS symbol isn't flashing than your phone is not using the GPS. Did you try a reboot?

 

This is true. But he never mentioned that the symbol wasn't active.

 

for your sake, I hope those spares are OEM!

 

Mine's been doing the same thing. Even with the maps app not running, my battery drains quickly & then says the Map App ate the majority of it. I do have the weather widget on my phone as well. I'll delete it & see what happens.

 

What did you use that told you what was using your battery? I dont know how to have the phone tell me what is causing the drain.

Thanks!

 

You can either download Spare Parts from the market and check partial wake usage, or you can go to Settings>About Phone>Battery>Battery Use.
