I'm sorry to hear how many of you are having issues with the update. My battery life on 5.0 was decent-I'd get about 5/6h usage with 12/15hr standby before I had to charge from 100%, I'd be at 20/25% at that point. When I upgraded to 5.0.1 on Thurs (ota) I was getting about 3h usage with 6h standby and being at 30-40%. On Sunday, I did a full restore as new from the phone itself, twice. Got it back up and running, sunk my apps and music fresh from iTunes, cloud for my contacts, calendar and photo stream. I can say doing that helped big time for me. I charged last night at 630pm to 100%. Left it off charger over night, and today, at 630pm, I've just plugged in to charge with 3% left. I was at 6h7m usage and 1 day standby.
My advice to those of you that are having issues would be to do a restore as new to your iPhone, it's worth a shot to try to see if it'll improve things even a little bit for you.

Did restore and backup from iCloud today, since that's the first thing the Genius Bar tells you to do, worth a try, only time will tell if it helped..
I'm a little shocked an Apple update actually had the reverse effect on the 4S's, things that make you go....hmmmm...
At one point we discussed the battery drain issue and he said that he found that the first few times the phone is charged, I should completely drain the battery. He said that improved battery performance significantly for him. Who knows? but I will give it a try.
I was charged at 100% before leaving for work. After moderate use, 5 hours later, my battery is down to 31%. What gives? The original phone at 5.0 had much better battery charges.

I know these delta upgrades are all the rage as well as backing up to icloud, but this as resulted in things being much different among users. This makes it difficult to narrow the problem down with multiple ways to do things.
OTA is convenient, but i still prefer installing the full OS over the delta. And being content that my backup in itunes is more complete. Restoring as new is a pain and so I plan to stay away from icloud backup and using OTA updates. Kudos if either works for you, but it makes things simpler for me if i need to troubleshoot and eliminates some culprits.
But anyway, the next step might be to restore as new and start from scratch if your battery life is unacceptable. It could also be that you're simply seeing this as unacceptable coming from a Blackberry that had better battery life. Our expectations come from previous experiences.
I am down to 63% battey with moderate use since it was fully charged 6 hours ago Most of the time in my office wifi was not connected and bluetooth was on for maybe a half-hour.
What's moderate use mean? Why would you not be connected to wifi...3G only would seem to drain it more. In 6 more hours with "moderate" use you'll be down to 23% or so. That's 12 hours with moderate use. Seems good to me. Since you're in the office, and use your office computer with itunes, why not leave it plugged in?

"Moderate use, 5 hours later" means different things to different people. We all know the usual suspects in battery life (searching, GPS, etc). The iPhone I think can use location services (GPS) at various times using various programs (like Siri for example). Nothing drains a batter faster than GPS (as anyone who uses a golf course distance program). I suspect GPS has something to do with radically short battery life. WiFi, in my experience with Blackberries and Android, doesn't do much damage. I wish that the "drain it dry a couple times" was the answer, but science doesn't point in that direction. The other thing that I've seen on various forums over the years is that the batteries of new model phones drain faster. That's usually because the owner is using more stuff on the new phone toy. Which makes perfect sense. Nobody had Siri until the 4S, right?

There have been some tests done and it is the backup causing the issue. Best bet is to backup the phone via iCloud or iTunes. Restore the phone SYNC it not restore. reset network settings and battery should be fine. I went from ok battery life to great.
My backup came from my home iTunes library ( a cable synch)which was made before updating to 5.0.1 on my original phone, which pre update had great battery life not doing anything different from what I am doing now with the new phone.
By the way I tried the wipe before settling on a new phone. It had no effect.
Also, the backup I used to restore settings when I got the new phone was from the wired synch of the old phone pre update, soI do not believe it is the backup causing the problem.

No idea on your backup or what not. I can only suggest restoring as new and checking battery life with that, input some settings to make it somewhat usable and try that. If still bad battery, you at least rule that out. It's a fairly new phone right? You couldn't have done that much to really need that backup restored.

I think the Apple senior tech rep I spoke with is on to something.
Last night I let the battery fully drain to zero and completely recharged the battery to 100%.
The battery drain since the complete recharge is minimal. I am at 94% after almost 5 hours of mild use-checking emails several times plus auto check every 30 minutes. Yesterday, before letting the battery completely drain and recharging to 100%, I was at a much faster drain rate.
I will continue to let the battery drain completely and then recharge to 100% several times as suggested by the Apple tech to see if there is a continued appreciable positive difference in battery charge.
