Oh it's deff a OS issue as i know two people with iphone 4 when the downloaded OS5..they got worse battery life..hopefully a new update soon.
Would suck for apple to have shipped 4 million units with defective batteries..certain it's the OS
Got a tip for us?

I hope they fix this with a software update. That's the only thing holding me out of getting a 4s.

If you guys haven't already done so, definitely call Apple (1-800-MY-APPLE), speak to a tech and tell them about your battery issue. You don't need AppleCare to do this since obviously we're all under warranty. The more cases they have on file about this the better!
What amazes me the most is the disparity of reports in this thread. My iPhone 4s is at 23% after 15 hours of being unplugged including 1 full hour of run keeper which keeps the high precision locations services running full time.
Back from the Apple store.
In hopes of getting my new iPhone 4S replaced because I had thought I had exhausted all measures to resolve the battery draining issue he decided to conduct a DFU restore which would replace the firmware of the unit. This, we had hoped, would repair the battery controller if that was the issue. Results below:
About the test:
- Lap counter would measure the time it takes to drain one percent of power.
- Airplane mode on.
- All applications closed.
- Brightness at 100%
- Auto brightness off.
The first shot is actually of the apple store's floor model.
The next shot is of the DFU restored iPhone to the right and my old iPhone 4 running the same test to the left.
The results seem to be the iPhone 4 gets about 4 mins 20 seconds to every 1% and the iPhone 4S gets about 4 mins.
What can you do with this information? Use it to determine if you have to replace your phone due to a hardware malfunction.
What is this telling us? This battery draining might be "normal".

Agreed. I went from 6am - 5 pm with heavy Internet, phone calls, app store, emails, etc. started with 100%, ended with 18%. Perfectly acceptable to me.
I have been suffering the battery issues consistent with several of the posts here of percentage drops every several minutes with no activity and meaningful drops overnight. I have performed one complete discharge and recharge cycle but it did not change the situation. I have now gone into settings one by one and disabled notifications, mail push (manual), Facebook push, location services, iCloud, iMessage, FaceTime, and anything else I could find that resembled background actions. I have also killed all active apps. I also disabled wifi but purposefully left the cellular data on so that I could capture any net activity in usage stats. After doing that I noticed over a continual flow of network traffic on ratio of 2:1 rx vs tx along with the continued drop of battery power. I assume background processes(s) are active and related to the data traffic when seemingly everything is inactive. Part of the data traffic may be related to the refresh on iCloud data storage stats one level above the cellular usage page but I don't think they would explain accumulating approx 500kb of rx traffic in 20min with nothing running. I have now gone to airplane mode which of course has halted the traffic and battery usage seems stable with music player running. I wonder if iCloud pushes still occur from other iOS devices regardless of iPhone stats. I wish could get a deeper process , mem, and net usage view similar to mac os activity monitor to profile this.
What was the result? Your phone didn't improve? Did they replace it?
I just ran the same test with my 4S and I went 4 minutes and 56 seconds for every 1% of battery loss.
They didn't replace it just the DFU reset and a battery test.
Is that 4 mins and 56 seconds consistent?
Personally I think iCloud setting backup is the battery drainage problem.
I disabled backup in iCloud. Now I have 60 minutes of use and 3.5 hours of standby. And still have 89%.
Before if iCloud and backup were set to on. For some reason it would show usage as 3 hours and standby as 3.5 hours and my battery would be down to 65%. So for me something about setting the backup in the cloud that makes the iPhone think or the phone is trying to connect to the cloud for 3 of those 3.5 hours (even though I definitely am not using it for those 3 hours it says I am using it for.

I'm about to die, but just by messing with settings I'm over double what I was yesterday and there's still some stuff I can turn off.

I know what you guys mean. It really is annoying. However, I've always (and this is because I'm a REALLY light sleeper) kept my phone in airplane mode overnight... It drives me crazy if someone manages to actually wake me up because I simply cannot. go. back. to. sleep! 
I suggest some of you try doing the same thing. And fear not, I'm sure apple will take care of things with iOS 5.1

Wow, it's taking a really long time to die from 1%!
I was getting consistent 6+min on the lap test. I don't know how accurate that is when it comes to doing more daunting tasks.

This made me chuckle. When I travel for work I put it airplane mode to shut it up at night so it doesn't wake me.
At home it never occurred to me to keep my phone in the bedroom. I plug it into the chargedrat my desk before going to bed.
Anyway, point of my post is to give a 4S datapoint: at this point showing 59% battery with 3 hrs 9 min usage, 9 hrs 49 min standby. I'll leave it off the charger tonight and see what happens. 32gb AT&T if it matters. This is not perceptibly different from what I was getti with my iPhone 4.
I might have turned off a couple minor things, but wifi, Bluetooth, iCloud, 1 exchange email/calendar and a gmail email are all on. I agree that if you have to turn off the stuff you bought the phone to use there's a problem and you need to figure out if it's some rogue app or the hardware of your phone (in which case get Apple to make it right)
I ran the test for 22 minutes and 58 seconds, and my battery went from 14% to 9%. I stopped the test as soon as it hit 9%. The average was 4 minutes and 59 seconds per 1 % lost.
disclaimer:
I may achieve different results if I ran the test from 100%. I am going to try the test again in the morning when I go to work and I will let you know of anything is different.
What is you phone averaging after the reboot at the apple store?
OK just like everyone I've been worried about my battery as well. I decided after spending the day working on the 1000's of tweaks on the innerwebs that I, based on Oppressed's testing sequence from the Apple Store, probably do not have a bad battery. I think the culprit is I have just been PAYING TO MUCH ATTENTION TO IT!!!
Here is my setup and process of events since I got my phone Friday at 5:00 PM EST....
AT&T 32GB Black Phone
Restored from backup right out of the box from a non-jailbroken AT&T 32GB Black Phone 4.
After spending the first day with the phone which was only half a day I didn't notice anything out of the ordinary. The next few days I started paying attention to the battery more and noticed the meter dropping 1% every few minutes. Sunday I did the "battery conditioning" and ran it down until the phone turned off and charged it back up. I noticed a bit better battery the next day. I spent alot of that day checking fantasy football scores. Monday night I decided to leave the phone on all night unplugged instead of leaving charged like usual. I noted the percentage before I went to sleep which was 86%. Woke up... 82%. My conclusion was I was getting poor usage times and great standby time.
Today was my real test. Kept the phone charged all night and woke up too 100% at 10:00 AM EST. Here is my phone settings and sequence of events today..

Checked and answered about 20 emails from work.
Answered approx 10 emails in my gmail account.
Checked Twitter for 10-15 mins
Checked FB real quick to clear out annoying badges.
Played a few turns of WWF.
Played two levels of Tower Defense.
Played around at Starbucks on the crappy Wifi for about an hour doing various things such as Twitter, WWF, Safari browsing, Reeder.
Showed off Siri for a few people. Set it up to call me master.
Got a haircut for about 30 minutes. This is important b/c signal sucks here. Literally dead. I put it to the test and used Twitter while waiting for my haircut. Also uploaded 4 screenshots to dropbox over 3G. Signal dropped to Edge a few times.
Tonight did various crap on Twitter.
Conducted 25 minute test on Stopwatch.
I should note that while running the Stopwatch test I had various apps running in the background (Tweetbot, WWF, Mail) Airplane Mode Off and BT on. Various Push notifications from WWF and Sportacular were coming through during the test. Few pushes from Tweetbot as well.
My conclusion. Considering I usually plug my phone in numerous times during the work day and also at home when I am not using it. This is fair results and I shouldn't be worried. I am leaving for Vegas in a few days and will really put it to the test with alot of photo taking. I was going to run into the Apple Store before my trip but figure its not worth it. My luck I will get a phone thats even worse. I should add my phone has never gotten warm at all. Been in a case since I took it out of the box. Check the screen grabs.
Sorry for the long post. I have gotten so much quality info from this site I figured I would share my experience today.
Thanks for listening.

Also having battery issues on my 4S ATT 16GB. Noticed something strange today, plugged it in last before bed and when I got up this morning turned the phone on while still plugged and the battery showed 97%. Don't know if it made it to 100% or got to 100% and started to drain after.
Got the phone last week and been trying to disable functions as I go, but still not getting decent battery life. Also noticed the back of the phone getting very warm. All I have been doing today was checking the forums & checking email, no games or music.

Here's my results... I formatted last night with iTunes Factory Restore.
Power cycled the phone, put into Airplane mode, Brightness at 100% with Auto-Adjust = OFF
I'll do this again when the battery get's really low before I charge it to see if it's consistent...
