hey i got the official one from sprint model number BXT6800, has 2100 omhs of charge. Out the box it had 50% charge and i let it die so i can give it a full charge and at 50% it lasted me a whole day. I just recently recharged it fully and will post back with results. Battery is not in stores yet so you have to direct ship to ur home. My girls works for sprint and got it for 37$ after discounts
