I had that happen to me and it was a pain in the ass...it wouldn't find my location and I couldn't get the gps signal to lock...and them randomally while it was in my pocket it would start to search for satelites and drain my battery...I took it to verizon and they cleared my phone completly and its worked ever since...it will do it once in a while but I just restart my phone. Its one of many dumb flaws with my droid 2 I hate
