Boredmug is dead on with the heat issue. Might want to pop the battery cover off when this happens and see how hot the inside of the device, and the battery feel.

I have a window holder for my car. Sitting in the sun while driving, I'm lucky if it charges for 20 minutes before it stops. Then I find myself holding it in front of the A/C for some cool down time.

Also experience same thing on the home charger if my phone has been in the belt holder too long and has gotten hot. Usually that only happens when I've had GPS or Bluetooth running and forgotten. That will get it good and smokey by the time I go to charge it back up.
