I just went on an 8 hour road trip with my Droid2 plugged into the Car Mount. I had GPS & Pandora on the whole time. When I got out of the car within 20 minutes my phone's 15% battery warning went off. I started to investigate this even more. When I'm not running anything the battery charges "seemingly" OK. When I'm running GPS the battery charges very slowly. When I'm running GPS & Pandora the battery actually gets drained as if the charger can't keep up with it. Does anybody else have this issue? I'm wondering if the issue resides in the battery, car mount, charger, or a combo of all of the above.
