Honestly, I'm a little worried about the battery life, because although it is a smartphone, none of my smartphones have had average battery life of LESS than a day. However, I'm sure there's something being overlooked here. With the same big battery as the TP2, there must be something going on behind scenes that's draining it. I guess we'll find out on Friday when we root our Evo's and see how the battery life is on 2.2.
