So this weekend was my first real world test using the GPS turn by turn for a long car ride (about an hour). I had everything all set plugged in and started the music player (not Pandora) running in the background while the GPS was displaying on the screen. I also had the bluetooth synced to the car. To my surprise, the battery started to drain. It was pretty slow but after about an hour around 5-10% of the battery drained even while plugged in. Do you think it is my after market car charger from monoprice (For only $1.46 each when QTY 50+ purchased - Motorola V8, V9 Series Car Charger for RAZR2 | Motorola It has been working great in the car for about 2 weeks with Pandora playing and bluetooth. Anyone else experiencing battery drain while plugged in the car using GPS? I think I read someone having a similar situation but with the Verizon charger. I am also using the stock battery. If not, please let me know which car charger you are using with a link if possible. I can't continue using this one if there is one out there that will keep me charged in the car. Thanks!
