The latest firmware took mine from 8 hours normal to 12 - 15 hours normal. Everything stock.

Thought I'd point out that I have an Epic and in tests I've run against iPhone's (3g, 3gs, 4g), it's been faster than them all at internet access. This went against the tests though showing the iPhone 4g was faster. Then, at the bottom of the page I saw that the iPhone's where benefiting from a 3g microcell. Talk about apples to oranges...

This article was written by people just barely technologically literate so I'll give another vote for it being written by someone's marketing department.

As for the battery life, I'm getting a solid day of usage out of mine (12-15 hours) after the last firmware update. They say they are rolling Froyo out now starting overseas so hopefully in a few weeks it'll make it here.
