I have 3 Incredibles on my account. I purchased 2 of the 1750mAh Slim Extended Life Batteries from Seidio. These batteries lasted a little longer but not much. Then I purchased 2 of the 2150 Extended Batteries from Verizon. These batteries lasted almost twice as long as the battery that came in the Incredible. This makes the phone a lot more useable. I hope this helps.
