I got roughly 36 hours on 1st full charge and playing around with it, then I let battery completely drain then charged it up to 100%. Ran for another 36 hours, then charged it from 50% to 100% yesterday, but then overnight it went from 80% to 35% with wifi off, so I don't know what the heck happened to kill the battery overnight when it was not being used and no music playing or anything.
Hope this doesn't happen often or I'm not going to be happy!!!!

Im going to let my battery run dry tonight then try a proper full charge and drain cycle again, seems a lot better in use but sometimes seems like its dropping faster, maybe im paranoid compared to my old 3g.
With regards to multitasking and apps using up resources, if you have an old app(ie not updated for save state/backgrounding) but its in the quick switch list is that definitely not running? when i tried multitasking on my jailbroken 3g 4.0 then looked in sbsettings process manager the apps all appears to be in some kind of running state still, maybe that was because it was running on the 3g (hacked on)
Ive made a habbit of shuting down what i can from the switcher list just in case.
Anyhoo after next charge cycle will do full day and get some stats, but my general setup is...
2x Push email (mobileme & exchange) 3x fetch imap (30 mins) Wifi normally off, 3g on (going to try a couple of days, one with it on one with it off) normally an hour or so of ipod use and some moderate gaming in the evemings, occasional foursquare checkins.

If you turn 3G off you should get a little better battery especially if you have Wifi which is faster anyway. I don't have a data plan never have, so every iPhone I've had has been JB with 3G off and I've always had better battery than my friends on Vanilla phones. Why not use the full capability of the phone and just plugin and charge whenever you're sitting during the day?

This was my battery last night. Worked it down to 20% then hated seeing the red and charged it lol.
I should clarify my settings:
- screen is dimmed with the control sitting right under the "B" in the "Brightness" title of the screen, and "Auto-Brightness" enabled.
- Wifi, Bluetooth and 3G always on
- 2 IMAP email accounts ( 30 min )
- 1 Contact & Calendar Exchange account

I cant post a screen at the moment, but I've had the iPhone 4 since June 22, and my avergae use so far per day is much like this:
8 hrs 30 min usage
23 hrs standby
In those 8 hrs, I'm backgrounding Pandora and Pockettunes, emailing, texting(alot), safari(alot), and using other apps like Facebook, Beejive, MLB @ BAT 2010 (to stream my red sox).....really the battery is great. If you have issue, restore as new, then restore from backup, shoud clear some issues...

Whoa i love it mine is getting better each cycle. It went from 6.5h to 7h to 7.5h usage 24-32h standby once i get the usage over 8 hours ill just use it normail I think ill make it this cycle. im where i was the first day with 40% to go.
i used an aftermarket charger and it took close to 4 hours to change the thing 17mins each 10% then from 90-100 one hour is that usual for the last 10 % to take longer a battery cell life saving thing. i usually use an apple charger that one was my back up at work

Hey guys here is a screenshot of my usage for today. Would you guys consider it to be consistent w/ what you guys are getting? I'm almost certain my 3GS battery would have already been drained by dinner time, so I'm pretty satisfied so far w/ the 4's battery.
Here are my settings:
- 3G is on at work from 8-5, until I get home where Wi-fi is on the rest of the night. Location services are turned on periodically.
- Brightness sits at about 40% w/ Auto-Brightness on.
- All email is set at Manual Fetch. Notifications on for BeejiveIM.
- Bluetooth on for around 30 minutes in the day.

Since it's a hot topic, anyone have any battery questions? Next week's Convertcast podcast we're having an engineer as a guest whose specialty is batteries. Thought it would be nice to talk about it, and finally put to rest the question of do you or don't you keep the battery topped off, and how often do you drain it completely.
