I have had my Note 10.1 for just a week and I am really pleased. Battery life seems OK compared to smart phones I have had and, like them, I put it on charge every night (battery down to between 10 and 40 percent). I use the standard Samsung Mains charger and it has always been 100 percent fully charged in the morning. However I have been unable to get the Note to charge at all using any other charger. Granted most of the mains/USB chargers that I have are rated at 5V and between 0.5 and 1.2A as opposed to the standard chargers 5V/2A. However I would expect them to charge the Note - only more slowly. But none of them charge at all. The Battery Icon is green with a Red Cross and using a Battery App it reports "USB connected" but the battery continues to report "Discharging" when the cable is plugged it. This is a minor inconvenience as I have one Note 10.1 and one charger. So as long as I plug the charger in where I need it then it's OK. However there is a much bigger problem. I also would like to keep the Note charged while I am out and about and travelling. To this end I already have two portable USB chargers which I use with a range of devices. A Powergen 8400MAh portable battery pack with two outlets. One of which is 5V/2A. This should be enough for a single full charge of the Note's 7000MAh battery. The second is a Car Charger (std 12V socket input) with two outputs the higher rated one being 5V/2.1A. Both of these are specified as being suitable for an "iPad"! Both chargers work, using the high power ports, with many other devices. However neither of these will charge the Note 10.1. Behaviour is exactly the same as with the non-Samsung mains chargers I have tried. This issue has not been reported before in this forum. If this is "normal" for a Note 10.1 surely it would have been. Does anyone have any ideas? PS. In all cases I have used the same standard USB cable as supplied in the Note 10.1 pack.
