Whats your standby? My first 3g had issues because when it was sitting on my desk it'd log usage data for no reason (something was draining the battery). After trying a restore and soft reset I decided to take it back on Friday because I took it off the charger at 7:30, was barely doing anything with it and was at 30% or so by 11. Apple swapped it out and usage/Standby ratios are much better now. It still logs 1 minute about every 10 of standby; probably because of push.
In any case if you watch your usage/standby ratio I think that'll give you a better idea as to whether you might have a problem.
That was a problem for me and was related to the mail hang issue reported here:

I have fixed that. I get 16 hours standby at that point. I just dont get how people are getting 5 hours and I am rarely above 4. I thought apple rates the phone at 5 hours browse time, which is basically what I am doing 90% of the time.

I bet 3D games take a lot of juice. Also, the screen did not go off the entire time. I had my sleep settings set to never.... it didn't even dim.
I had the bug today where standby and usage times count in parallel. And the battery wasn't being used more, so if I had just let it sit around for two days I could probably have posted screenshots with 40+ hours of usage.Personally, I think some people have lied in this thread. It's very easy to manipulate screenshots. Any insane numbers we see are most likely bogus posts. Batteries vary slightly, but it's impossible to get some of these numbers. Not unlikely, impossible.
Shouldn't we come up with a way to test the battery? Like... do a full charge and use all the same settings and come up with a controlled way to use the battery. Then the results would be more accurate. You never know if the person is using some intense apps or if they're just checking their email every so often.
apple.com said:Video playback: Testing conducted by Apple in May and June 2008 using preproduction iPhone 3G units and software. Video content consisted of a repeated 2-hour 23-minute movie purchased from the iTunes Store. All settings were default except: Call Forwarding was turned on; the Wi-Fi feature Ask to Join Networks and Auto-Brightness were turned off. Wi-Fi was enabled but not associated with a network. Battery life depends on the cellular network, location, signal strength, feature configuration, usage, and many other factors. Battery tests are conducted using specific iPhone units; actual results may vary.
Although I didn't read all posts and checked all posted screenshots, it makes no sense to forge results, at least judging from the screenshots that I did see.
Testing conditions vary but the average should be around what Apple claims to be, for they themselves must have done due diligence testing and posted not their best results but rather either conservative or median/mean values.
To get a better idea of how well your battery performs, jailbreak your phone, install BossPrefs and enable numeric battery -- it will allow you to switch between the graphic bar and numbers by tapping the battery indicator. iPhone shows 100% green when in fact the battery is 90% charged, for instance.
Then... run tests like: browsing for 10 minutes and measuring how much battery juice you consume. Heck, you don't even need to go on for 3-4-5-6 straight hours and just use a simple formula to calculate how much browsing you'll get if you know how much 10 minutes of browsing consumes the battery. Obviously, that's provided the battery demonstrates equal performance, be it at 100% or 10% charge. It should though.
My talk time is around ~4 hours (+/- 10 or so minutes). I get ~24 minutes on 3G (full signal with all bars, PUSH and any other background process--such as SSH--off) for every ~10% battery charge.
Make your screenshots with the numeric battery indicator, not the graphic bar.
Cheers.
I don't have the time or patience to go into what I have already done including speaking and going to both AT&T and Apple, but here's the latest.
Yesterday I had an appointment at the Crapple store. The so called 'Genius' was an ass! He said oh everything is normal. Oh really? Freezing, crashing, bad battery... If that's normal to Apple they have serious issues.
I love the phone but the battery SUCKS!!!😡
New tagline: "The new Apple iPhone 3G, it may be too cool for words but the battery sucks and it will freeze on you. Enjoy!"
I've been on vacation so I haven't been using the phone as much, but I still thought this was good.
This is similar to what I achieved whilst I was in Paris last week..
Not using the phone as much, mainly for apps that were downloaded and could be used offline, very little WiFi... some texting.
