Because you are basing it off of capacity and not actual usage time. Typically, a 1900 battery equates to about 2 additional hours of play time from the 1730 mah battery the EVO 3D comes with. If reviewers say they are getting about 5 hours of heavy usage then I should get about 7 hours with a 1900 mah battery. The Seidio 1750 mah battery in the EVO gets around 6 hours of playtime and the 1500 mah stock battery gets about 4 hours of playtime.
