I am still wondering, is this acceptable? I mean, for me to use this phone for it's purpose, and in that it is ruining my phone/battery. To me, that just doesn't make much sense.
I think it's completely unacceptable. I've had my Droid 1 for 17 months and never had any problems like that. I use navigation a lot too. I would guess that there is something defective with you're phone.
You've had the problem on and off the dock, right?
