I went back thru and re-read a few of the reviews... most of the reviewers seemed to have focused on the 4G battery life.
For those that did evaluate the 3G battery life the consensus seems to be that it will last for a full day of medium to heavy usage. Which is quite a bit better than the Evo 4G. Most reviews of the 4G said that you could get thru a whole day of light usage at best (when stock).
I'll admit I'm a bit disappointed with the battery life claims so far since I expected the Evo 3D to have class leading battery since the sensation was deemed to handle a ful day of medium to heavy usage with a smaller battery.
My minimum requirements for a smartphone is that it handle a day of medium to heavy usage so it sounds like it will meet my needs but I was hoping for more.
Side note: do any 4G phones get good battery life if the 4G radio is left running all day?
