Hey folks: A few weeks ago, I got the R2D2 Special Edition Droid 2 (woot!) And I have a quick question regarding GPS and battery life. I use JuiceDefender as a battery life extender (free edition of it,) and I have some simple power saving things set up with the default Droid 2 battery manager. I've started to use Foursquare, however, and with it, I've been turning on my GPS "switch" when I go to check in to somewhere, and then turning it off when I'm done. However, I've noticed that when I leave the GPS on, it just reacts quicker to Foursquare and Navigation, even if the GPS icon isn't flashing up top near the signal, running apps, etc. My question is: will leaving the GPS on drain my battery faster, even if it's not blinking up top, denoting the GPS being used? And if it will, can I disable something so that the "Switch" stays on all the time, it will only access the GPS (draining power) when I use a program that accesses the GPS system? Sorry for the long question! Just didn't know exactly how to phrase it. Thanks in advance!
