I've tried different cables, ports and car plug outlets. I first thought I had a phone issue and VZW exchanged it for me. The phones both seemed to charge fine initially, then exhibited the above problem. Again, works fine using AC but this is quite inconvenient to a frequent traveler.
Thanks for your consideration.
for a computer I think to get adequate charge you need DeskTop manager installed (unfortunately not supported on MAC)
not sure whats up with the car charger, could be the port in you car is bad
