Ah, okay, well not having read a lot on the location services yet, I guess there is a lot to be studied here. I'm assuming the screen curtain on the phone behaves differently from the computer? I can see how turning the screen to black may not benefit battery life, but if on the phone it actually disabled the screen in some way, that would save battery life. I'll go read up on location services, since I haven't found a real GPS or route solution yet, I probably don't need this right now. I am looking for such a solution and if you have any thoughts, I'd be interested. Thanks for the tips, I'm always looking for info to help further my knowledge.
