Need help with 1020 Camera Grip charging

[Majin Static]

Just picked up a 1020 today. Bought the Nokia camera grip with it. Was letting both charge and I noticed the camera grip wasnt charging after the phone itself was fully charged. I dont know much about the grip so I was just wondering if this is normal or if there is another explanation.

Just out of curiosity. I don't own a 1020 but I did a quick read on it. It would appear it has it's own charging port and indicators. Where you trying to charge it while attached to the phone?

Where it should be. The bottom USB port. It'll flash up to 2 lights then just quit charging until I remove the phone.
