Running Fresh's rom I get about 10-12 hours. On a normal day I:
Send 20-30 texts
Check Facebook 2-3 times.
Talk anywhere from 15-30 mins
Randomly look things up on Google.

I've had phones that do better, but honestly to have a snapdragon and huge screen you can only expect so much. I ordered the package off of ebay with 2 batteries and a charger for 9.95 and I can say that the batteries I got are just as good as the stock one, so I usually carry an extra if Im gonna be gone a while.

When you first get the EVO for your first 3-4 battery cycles the bat life is gonna be insanely bad, but it gets much much better after a few days.
