    This is a battery test i performed with MYN's Warm 2.2 ROM installed on my HTC EVO with the following battery saving tweaks done, most of them can be found within Mr.Virginia's guide found http://androidforums.com/htc-evo-4g/98174-evo-battery-life-vs-hero.html#post922934

    Signed out of Google Talk
    Screen Brightness to auto
    Always use 3G (Airvana in the house) but if bad signal, switched to Wi-Fi
    Disabled Always-On Mobile data
    Changed account sync time
    Haptic feedback off

    As always, these results do not mean that you will have a similar outcome and only reflect my personal usage of my phone.

    UPDATE: My screenshots will not upload, any suggestions?

    I thought automatic brightness killed your battery

    The moral of this story was supposed to be that I got 37hrs on one charge and still had 39% battery remaining. But it failed. Horribly.

    How long were you actually using the phone? I just got about 50 hours out of a charge. Of course, it was idle for most of that time. Also, it's actually better if you keep wifi on if you're connected to an access point. It uses less battery power than 3g. Auto-brightness is neither here nor there. In brighter areas, or areas where the brightness has to adjust a lot, you're much better off keeping it constant.

    Use- about 2-3hrs
    For me personally, even though it is not supported, I ALWAYS have better battery life when I'm in my house with the Airvana and full signal strength than on Wi-Fi. Probably just me
    And I've never taken much stock in brightness when it comes to battery life unless you're running the phone alot. But it kind of upset me that my screenshots didn't work. Anyone here who posts screenshots use a certain app?

    Well, it's certainly not a hard fast rule. If you get better battery life by staying on 3g when you have a really good signal like that, then certainly do that. It's not going to be the same for everyone :). As for screenshots, I just use shootme, then upload the screenshots to either photobucket or just to my dropbox. You can insert them into a post as a picture either way.
