Interesting....I start at 80% battery...insert the Dx into the official moto car dock and car charger...drive using nav for 3hrs and my battery is down to 50%.....

I also stream pandora simultaneously....

I would expect the charger to keep up but it is a losing battle....

Happen to anyone else?

Weird....

that is really strange. does it show that it is "charging"? i would still think it would charge, even with those things going. it should, anyway.
 
I had this happen with my original droid and found out it was because it was getting too hot. When I rearranged the dock so that my air conditioner could get to it, the battery would no longer drain. So, my theory is that the battery gets too hot and can not charge appropriately.
 
Can't speak about the X but I have a friend with an Inc. If he uses Navi. and radio at the same time, his battery drains despite using a car charger. I think it's because the car outlet doesn't supply enough watts.
 
I was having this issue when using my old LG charger with my DX. Some research told me that it was <500ma which makes me think it just couldn't keep up. I was using navigation and bluetooth at the time.
 
When I called about battery problems one of the first things the tech support guy told me was that Verizon was advising X owners not to rely on the car charger for recharging.
Which was admittedly was a wtf moment but I didn't press him for more info because it was unrelated to the problem.
 
I heard about this problem from Magelan GPS forum - When your device directly on sun and battery getting hot - it stop charging (they design this way - afraid that it can explode). So, we have to live with that and somehow avoid overheating. Do not blame tech support.
 
I had my X and Vibrant plugged into a dual car charger yesterday and the X was draining while navigating.

I think I was at least holding even when it was just the X plugged in.

Also, it seemed as if I kept the screen off, the charger could better keep up.

I am having the same problem. I went by the local VZW store and they ordered me a new X. They say it is a hardware problem. I have a release day X.
 
Well the car charger doesn't charge very fast at all.
And I found out it doesn't charge fast enough to matter once it goes dead. Once my phone goes dead, I can't charge via laptop or headunit in the car. Have to use a regular outlet.
So I would say it just doesn't provide enough charge? I'm sure you can charge it with some modification though. My buddy runs his laptop and phone from an outlet in his car. Heavy duty laptop too, 17 inch screen gaming laptop with a regular droid. Then again his car has 6 batteries for his competition system, so it may just be theres enough power to the stock outlet. Could see if theres a way to increase the ampage (sp/ct?)

Most stock car chargers limit the current to 0.5A, which is the same as the USB port on a computer (when configured else it's 100mA). The wall charger that comes with the phone is rated at 850mA. I would recommend a car charger that is stated for at least 1A, even then that is not continuous. Your buddy is probably using an inverter in his car, but keep in mind most of the USB ports on those inverters are 0.5A as well. Personally, I went with a 2.1A charger and it's worked out great so far. They are hard to find, but almost anything that lists iPad compatible is probably around the 2.1A mark.
