I planned a trip for my and my gf from Paris, Texas to Dallas, Texas. The phone was fully charged using the 110v wall charger. I put the phone in the car dock, and it showed it was charging. I used Navigation to get directions from Paris (Texas) to the hotel. The trip was about 2 hours long. The only other app that was running was Weatherbug Elite, and the update time is set to 4 hours. Strange thing is, by the time we got into Dallas, the battery level was 30% Is the VZW car charger not able to keep up with the charging requirements when using GPS Navigation? If that is the case a 6 hour trip would require a real GPS and I might as well go back to a Blackberry. Thoughts/Ideas/Suggestions?
