i have 2 evo's. I have used both sprint's and the $10 amazon battery(sprints is 2500mah and the other is 3500mah). Both are the same size. Both performed exactly the same after 1 week of testing. So i sent sprints back and got a $110.00 credit and used $40 of that to buy 3 amazon batteries.(using my TP2 to charge them). Get the 1's from amazon(my phone is stock with all current updates).
