Discuss Tips to Maximize Battery Life Here!
Sorry to the Mods for plugging a different site, but I found a thread of a guy that got:
61 hrs of use with 24% of battery remaining
He explains his usage patterns, how he set up Advanced Task Killer, etc. on an Evo prior to doing his test.
Tip-Trick: 61 hours, 24% battery remaining - Android Forums
You might bookmark that page for reference after next Friday to optimize your battery life.

I'm with skullsdontfade - I'll use his techniques and find my own mix of what I want running. Having some widgets running is part of the beauty of the phone...
At least we know what to do now when our batteries are dying earlier than we wished.

so in summary for me -
1. Turn off 4G and hotspot.
2. Turn screen brightness to low or medium. disables auto brightness.
3. Settings Wireless and Networks, Wi-Fi Settings, <menu button> Advanced, Wi-Fi sleep policy, Never.
i'm not sure about the 4G off. i live in a 4G market so i'm hoping i can leave it on. will have to test.
regarding the Gmail app, at this point i think i prefer it over K9 so will try to stick with the Gmail app.

In his article he also said to use a task killer...which after reading an article about how task killer's do more damage then they do good. I've changed my perspective on. In my Evo i def will not be installing any type of task killers. But i will take some of what dude said into consideration. Good find!

WiFi is designed for short range, semi-permanent connections: it doesn't need much power because of the range assumption, and needs less "handshaking" communication to maintain the connection since both ends assume that the other is more-or-less staying put in one place.
OTOH, Wimax and 3G both use a remote tower, and need to assume that you're a moving target that might be driving from one tower's area to another. More power to connect to a remote receiver (this is a big effect - remember signal strength goes as r^2), and more communication needed for handshaking, even when you're not actively moving data.

Obviously if you spend most of your time in range of 4g and out of range of wifi, I'd change my recommendation. But if you've got WiFi access, it's almost certainly less power hungry.

We're going to be inundated with real-world reports of how users in different areas are seeing their batteries run down. For me, I'll be running the Evo either at home or at work, both in strong wifi zones, and I don't live in a 4G area right now. I'll only have the option of 3G, and I'll only be using that when I'm out on the town. I'm also pretty miserly with screen brightness, apps, etc., and my phone will (regrettably) be sitting idle for a lot of the day anyway. I expect to get more than a couple of days between charges if I forget to plug in for the night.
