Yeah there's no way to know where it exactly was in battery life it could have been close to make that switch to one less "bar" on the battery meter . But everything points to this phone having slightly better battery life then the EVO . The processor , screen and 4G network should all use less power .
But I'm not expecting anything great outta the box , once it's rooted and some good kernals are out there I"m sure I can match my Incredibles battery life of 20-40hrs depending on use . And honestly as long as I can get in the mid teens I"ll be happy
