Guys... just check how much data has been downloaded/uploaded during the battery drain issue!! U'll be amazed/disgusted 
! I've got like 600MB data traffic during the drain issue (the data traffic was done on GSM although I have WIFI in house )... now that will make me think twice before putting beta software on my phone in the future!
Either way, disabling gsm data fixes the battery drain (and saves your wallet).

Really? This hasn't happened to me.
For a while I thought I was crazy as most people were saying beta 4 was practically ready for the gold master and I've felt that I've had more issues with it than any of the other iOS 5 betas.
My phone was heating up incredibly and running through battery at the rate of a percent every few minutes. I think the heat of the phone has really been affecting performance and I was worried that the device might fry itself.
I tried turning off "traffic" in location services and even adjusting the settings for iCloud without any luck. As someone else noted, my data usage the past several weeks is much higher than ususal, though I'm not sure what data I'm transmitting.
So far the best solution has been to turn off 3G data in the settings(bummer). The battery still seems to be draining faster than normal but some of that is to be expected during beta. Either way the phone has been at a normal temperature since. I'm also frustrated that my personal hotspot is no longer working for iPhone 4. Hopefully the new beta will be out shortly.

Hmm ... mine is about the same and usage has not changed ... only thing I did was installed it as fresh ... i.e. reset the phone on 4.3.5 and then connected itunes and restored the Beta 4 ipsw and setup totally fresh...
Have everything running ...
Standby - 23 Hours 44 Minutes
Usage - 4 Hours 5 Minutes
Call Time - 17 Minutes
Data over 3G - 56 MB
Battery Left - 63%
And yes the BT stack issue sucks ... but hoping for Beta 5 to fix it atleast

Yes, our temporary fix was short lived on our iPhones as well. It's strange, because when the drain started accelerating yesterday afternoon, I did the same fix (turned off then plugged into computer to completely charge) and it slowed the drain almost back to normal.
I did the OTA update with both phones, so I'm going to restore both through iTunes tonight and see what happens.
I'll report back.

Possibly Wi-Fi iTunes Sync?
I've had battery drain & warm phone with iPhone 4 iOS 5 beta 4.
Disabled wifi syncing with iTunes & I think I've solved the problem. Will keep an eye on it over next 24hrs. Let me know if this works for others.

You can disable wifi syncing on the iPhone summary page of iTunes by unchecking the wifi box. If enabled, you can still manually sync iPhone over wifi even if not plugged into charger.
The reason I thought it may be wifi syncing causing the drain is that if you have wifi sync enabled in iTunes, the iPhone constantly shows as connected when on the same network, which must need some power to do.

That's the first thing I tried, and it didn't help. Never even slowed it down.
Wifi syncing isn't it. Although it's enabled, I spend the majority of my day at my office without my mac.
So last night I did a complete restore, and put beta 4 back on through iTunes instead of OTA update. Both phones seem to be better today. We still have location services off, however.
I'm also experiencing the same issue on my i4, I did the OTA from B3 to B4, and the battery would melt away, and the phone would get super hot, one day even displaying the over temperature message.
I did a shift-restore with iTunes and put a fresh copy of B4 onto it, and restored from a prior backup and it seemed ok at first but I'm still having the issues.
All of my iOS devices are being affected by terrible battery life. I went to sleep with my iPad2 being at 90%, woke up less than 8 hours later and it was at 30%. My iPad 1 isnt as bad, with it going from 90% to 50% the next morning
I've found myself the past two weeks needing to be tethered to a charger most of the day to make it through a standard work day (its my personal phone, so gets very little use during business hours and maybe a handful of texts).
I've disabled the traffic and wifi sync with no help, the only thing getting me through is lowering screen brightness and turning off wifi/bt/3g data

I've deleted my Gmail Exchange mail account & my iPhone 4 is definitely running cooler now with longer battery life.
I read on other threads that Exchange mail accounts can get caught in some kind of loop with the server & cause a constant battery drain. You can either delete the offending mail account completely or turn off the elements of the account in mail settings (Mail, Contacts, Calendars, etc), run the relevant apps (Mail, Contacts, Calendars, etc) to clear any stuck loops, reboot phone then re-enable the mail account elements that you disabled.

I was having the same issues with my battery life, just draining with no usage at all in both my iPad and iPhone. What I did to fix it was completely delete the iCloud account. That solved it on both devices and now my battery life is pretty great, better than 4.3.3.
I can confirm this as well, doing a full restore didn't help.
I upgraded to beta 5 and had the same problems, the only fix is to delete the iCloud account.
I'll have to stick to iTunes sync for now.
No more issues for me in beta 5 on iPhone 4 GSM. If you're still having issues I'd reccomend a full restore to beta 5 rather than the OTA update.
Battery life has been an ongoing issue for me since the upgrade from Beta 3 to Beta 4 and finally Beta 5. I'm actually considering reverting to Beta 3 just because I love the features, but I hate the battery life. It most likely has to do with iCloud, since I remember reading something about iCloud being enabled in Beta 4, or something to that effect. I've just deleted my account, and charging a completely dead iPod ATM. I know, it's not an iPhone, but this thread was actually quite relevant to my problem.
Also, wouldn't Airplane mode help if all you want is extended battery life? Obviously, if you're using an iPhone, you can't communicate, but it would seem as if this would work if you just want your phone to live long enough to play music 20 hours down the road.
