iPhone 3G Battery Life Not Great, But Better Than Most

That's a gross overstatement. They are not physically compatible and share little more than their name.
CDMA (access method) should not be confused with CDMA2000 and WCDMA (protocols).
One of those "small" differences is a massive power draw differential. The only way the difference between "CDMA" and W-CDMA/EVDO can be small is if you are not, in fact, referring to CDMA2000 (RTT), in which case you're making an inept comparison.
If the technologies were as close as you claim, there would be no particular incentive to switch out of 3G mode for the voice calls.
Actually, UMTS/WCDMA/EVDO and GSM/CDMA2000 (RTT), are both more similar to each other than WCDMA and CDMA2000. The difference between TDMA and CDMA is a minor (albeit fundamental) distinction in comparison.
Yeah. My wife is a non-charger, so it's just been great that our Al iPhones just go and go and go. The faster speed just isn't worth about half the real-world battery life. I count on mine too much for music to feel like I'm constrained if I need to make calls or use EDGE date, because I'll quickly get down to having to spare the remaining battery life for one or the other use.
But this is usual: Early adopters have to wait for full feature sets, live through waits for bug fixes in firmware updates and sometimes even hardware repairs, but ultimately the deal is usually better, because they WILL, EVENTUALLY, fix everything and you have something for which few corners have been cut to reduce base manufacturing costs.

Sure turn off Push. Turn off Bluetooth. Turn off WIFI. Turn off FETCH. Turn off 3G. LOL, we should call it the OFFPhone and not the iPhone.
Besides you pay $100 for MobileMe turning PUSH off makes it stop functioning.
This was my experience today (Day 1)
9AM off the charger this morning after 12 hrs of charging. 6PM phone was totally discharged and shut itself off. This was what I did with it today:
Bluetooth OFF
3G off
Wifi ON and connected
Push On (with PUSH off MobileMe is useless)
Fetch OFF
ONE (1) Phone call of 2 minutes all day
Lots of emails received (2 replied to) which is why I need PUSH
1 game (Monkeyball) "demo'd" at work for 3 minutes
Maybe 20 minutes of "surfing the web"
That's it. ZERO POWER. After 9 hours.
Totally DISMAL and useless.
What good is a phone like this if you have to babysit it all day or keep it on a charger.
Soemthng is wrong.
Yes, I have the newest software update.
I really WANT to keep it. But this is absurd.

9 hours of wifi on is pretty damn good.
There's a price to be paid for high-power wireless connections. It's not specific to any particular device. Small batteries drain fast. That's just the state of the technology.
Not really. Looks like it's working exactly right.
Constant connectivity means frequent charging.
I don't buy that for a second. My TILT with the same features turned on ALL DAY lasts almost 2 days with the lite use I give it, not 10 hrs.
They updated the list with all the ev-do blackberry's (but they still haven't included the LG Dare).

OK, today I turned EVERYTHING (except PUSH) off. If I turned PUSH off I'd have no MobileMe email. No GPS, no WIFI, no 3G, no BT. Now I have a lovely "offPhone." My time from "charger to dead battery" increased to 12 hours.
12 hours.
The ONLY thing I did today was receive about 60 emails. Made 1 call of 7 minutes. No web, no games, no GPS.
12 hours from full charge to dead battery. You gotta be kidding.

Hmm, that does sound a little low based on my experience.
On my iPhone 3G the settings are as follows:
Wi-Fi on (and most offices I'm in during the day do have Wi-Fi)
3G On (generally good reception in DC)
Bluetooth On
Brightness adjusted to taste (about 25%) and Auto On
6 email accounts set as follows:
-Yahoo! fetch manual
-IMAP account 1 fetch every 15
-IMAP account 2 fetch every 15
-IMAP account 3 fetch every 15
-IMAP account 4 fetch every 15
-IMAP GMail fetch manual
-MobileMe (all services) push
Cumulative talk time for me typically is about an hour during the work day. About 10-15 minutes using a Jawbone Bluetooth headset.
I probably get about 40 emails a day and usually need respond to about 10-15 using the iPhone.
Web surfing in the iPhone for about half an hour. Twitterific throughout the day.
I typically have made it through a 9 hour workday with about about 10-20% battery life left. That makes me uncomfortable, so I do charge it during the day if I'm at a desk.
Initially I had my Yahoo! on push and GMail 15 minutes. Brightness was higher too. And my battery life was really awful.

Sorry, but there's literally zero chance of that being true. Something is different in your configuration. I suspect you don't use push email with your Tilt, or you are not comparing equal connection times.
The Tilt's battery capacity simply does not support what you're describing. It supports a maximum of four hours of 3G or wifi web browsing.
If you don't turn off push, it doesn't matter that much what else you turn off. Switching off wifi and 3G should and does increase battery life, but by more than you're describing.
Edit: You can get about 6 hours of web browsing out of the battery and should get around 15 hours of your "light usage" with 3G and wifi off.
Either you haven't followed the battery break-in instructions, you're not being honest with your time reporting, or you have a bad battery.
True, the tilt may support 4 hrs of TALK TIME. My talk time is less the 10 minutes per day on any of my devices so they all EASILY last close to 2 days until I need a charge. The iPhone doesn't come close under the BEST of circumstances. However, I did find the GPS has been on. I thought it was turned off. Turning off the GPS (leaving on PUSH yesterday then then PUSH and 3G today with GPS disabled) has improved battery life to get me through a work day. By the time I get home it's got maybe 20% left which is much better then before. It seems the GPS is KILLING the battery. Tomorrow I'm going to try PUSH, 3G and Wi-Fi on and see what happens and Sunday I'm going to add Bluetooth. Each day I am adding one feature to see how it affect battery life. So far it seems GPS is the key to the bad battery life.
No, field tests show the Tilt at about 4.3 hours of talk time. I refer to the browsing time of the device: 4 hours on wifi, somewhat less on 3G.
Talk time figures place an absolute ceiling on data connectivity time, as well. Wifi browse times are universally less than voice talk times. 3G data connectivity varies based on the manufacturer of the radio and the network it's on, but is generally less than the talk time.
From what I have read, the new 3G iPhone has made some decent improvements over the 1st gen version. And if I understand what I have read on this thread so far, if the user was to operate this new 3G iPhone on the Edge network (or in the same manner as the 1st gen iPhone) then battery life is actually longer in every way. Is that correct?
So what is the final word? Should a person purchase the new iPhone 3G or not? From what I have seen there are no other phones that even come close to the web browsing capabilities of the iPhone.

My 3G battery really isn't that bad at all. I get 5+ days in stand-by with around 3.5 hrs used. Can't ask for more.
You gotta be the one kidding. Listen man, if you don't like the phone, return it, that simple. You're complaining about battery life, yet you're keeping on your push option, which keeps your phone connected all day, which obviously will run through your battery quicker due to a constant connection, and on top of that you are leaving your wifi radio on. Come on dude, don't expect this thing to have an ipod battery life with so many battery intensive features turned on. You gotta compromise somewhere if you really are that concerned with your battery life. Using the fetch option, with wifi off unless you are browsing will give you a big difference in battery life. Leaving your wifi on will constantly search for a signal and connect to signals that it finds throughout the whole day, which of course is going to require battery power to do so. Push drains more battery as it has to remain connected EVEN when you aren't recieving any emails, so it doesn't really matter how many emails you are recieving because the phone will still stay connected in order to be ready to recieve any emails almost instantly.
And I call some serious BS on your Tilt claims, that just is not true, Wifi is power intensive no matter what device, thats something you can't avoid or lie about.
I have found that the battery life on a 1.gen 2.01 iPhone to be much better than on the 3G iPhone. I never ran out of battery with my old iPhone. Now with the 3G I ran out twice already...
If I disable 3G and location services the battery life is much better but still not good as with the older model. Usually I have 3G on, WiFi off, Location Services Off and Push On. The iPhone lasts between 10-12 hours with about 4 hours usage. 2 hours music, 45 minutes video podcasts, and the rest internet surfing and 10 mins phone calls.
I got a battery pack today and I will always have it together. That way I can enjoy my iPhone more and I won't have to think about disabling features...
I ordered the Brendo usb pack and it seems to be working just fine.
