I had the same problem. Like everyone I checked all the connections, tried a new charger. I replaced the battery, it works and charges like a charm. I checked the voltage on the old battery and I have a dead cell. Took to a local hobby shop to confirm, it was a dead cell. They told me that the Lipo Batteries won't charge if you have one dead cell. So, check your connections, and buy a new Samsung or LG Battery and it will work fine.
