Right, After the "Not enough..." message, it will charge but it will take too much time. 1.5 hours of charging will give me about 45% of juice. So to get 100% juice, i need like 3.5 hours of charge? which make no sense. Through PC usb 1.5 - 2 hours of charging us enough to make 100% juice.

But the first time im using N9 i don't have this problem tho. It only appear after the night i update the system from 1.2 to 1.3.
