My homeboy had a similar problem. He overloaded his battery, and it literally popped at the seams. So he used a battery that he had from a cheaper samsung phone that he had previously through verizon- same size, same voltage and everything, but it would not charge through the admire... He had to charge it via his old phone then put it into his newer phone to use it. He did eventually replace the battery, but I thought it was odd that it wouldn't charge via the admire even though the battery was a samsung and as far as I could tell, identical to the admire's.
