I have a Samsung note pro 12 inch only 4 months old and suddenly the battery wouldn't charge when I was on it or even on standby. It was also very slow when the tablet was off overnight. I'm in France and using a proper Samsung charger. I have just discovered that if I turn the charger the "wrong" way up it is charging like it used to do. I used to have it going via an extension cable and I think it was just fluke that I had it plugged in the right way round as the extension socket was on the floor, not vertical as when a wall socket. Hope this helps someone - only really relevant if you are using a 2 pin plug...
