... I have a lot of widgets (which I am trying to eliminate to save power), and one of them is likely trying to get a location (likely the weather widget). ...
Good point. I've used rooted phones so long I'd forgotten there was any other way.Battery saver apps can only control GPS if rooted.

All,
I have tremendously incresed my battery life by unistalling power hungry apps (most I havent been using anyway), as well as disabling the "sprint connections optimizer" (which was using the GPS a lot), and by adding LEANDROID, a simple app to shut off mobile and wireless when screen is off.
Thanks everyone....
I'm the developer.
