Battery loss while using Navigation in the car?

[dave.cox]

I have found that the car chargers will often not charge the Motorola phones correctly,a the voltage is a bit too low for the charger circuit. You would think that Motorola would know better, but I guess not. Any way, I've found that using the AC charger with a power converter will work much more reliably.

I have no problem multitasking and charging my phone same time... I use a ZaGG usb charger however.

Also, this could be a heat issue. I know that my phone will stop charging if the battery gets too hot. So putting the phone under load and having it in the car window with the sun beating on it would probably cause it to heat up pretty quick. Just a thought, I could be completely wrong though.

Good call on that one. Since the battery is immediately behind the Kevlar (which is then immediately behind the black phone mount), and will absorb sunlight as heat pretty quickly you may be on to something. Even in a cold car, the sun could heat up the back of the mount (and the battery) potentially to a point where the thermistor shuts down charging. It may not be the cause in this case but it's something worthy of keeping mind of.

The only time my car charger didn't keep up with music and GPS was when it wasn't seated all the way.
After about an hour on the road I noticed battery level dropping, and noticed the nice blue led wasn't lit up on the charger.
Pushed it in and it started to make up ground and was topped off an hour later.

Use the motorola car dock, out keeps up with charging and it's easier to navigate music

I had been out of the forums for a while now, and WOW all the replies. Yea my generic car charger works great for just music and charging, but maybe it has issues when doing more. I will go out and buy a car charger that is made for the Razr and see how that works...

Thanks all! This forum is simply amazing for any questions that need answers!!!
