I just got a replacement EPIC from Asurion, and it came with a new battery. It's a generic battery with Sprint branding on it, but it is 1520 mAh instead of 1500 mAh. Also, the fact that it's probably a fresh battery means that I should be seeing better battery life; but I don't want to jump to conclusions just yet. Does anybody know which battery I should use? I've had my old one since the end of November.
