So, with what I think is pretty hard use with GPS and 4G on all day, with one large upload to YouTube, watching some youtube, taking a bunch of video, uploading screenshots and photos to flickr, listening to pandora, e-mail, phone calls, web browsing, twitter/friendstream, a bit of Skype/Fring, google maps, and several app downloads, the battery and EVO performed admirably!

I will definitely keep a spare battery on hand and I have a battery charger that doubles as a USB phone charger too. But really, all told, I'm pretty impressed.

A few notes:
At 15% battery, the unlock screen gave a visual warning to plug in the phone
At 5% battery, the phone chirped an alarm and gave a visual warning to plug in the phone.
At 1% the phone seemed to do an orderly shut down (with enough time for me to take a screen shot)

The phone still went 1 hour 37 minutes between 15% charge alarm and 1% shut down and I was still taking video and uploading screen shots much of the time.

Here are some screen shots for you to check out:
