I agree: battery drain is much worse in 6.0.1 than in 6.0.
With bookmarks sync switched off and not using safari I was back to 1.5 days battery with 6.0.
Now it's not even a day.... rather only 9 hours. That's unacceptable!

Yesterday I installed Ios 6.0.1 and recnarged battery to full, i unpluged at 14h20 and used normally...today at 7h05 my battery is 90%...I hope that for me 6.0.1 solved my battery drain, i want to see when i need to recharge it...

I found that 6.0.1 didn't solve the issue and had completely had enough. Went to the Apple store to complain even though I didn't have an appointment. Really excellent guy listened to my frustration and that I'd done a DFU-restore etc. to no avail.
When I showed him that the usage and standby counters were within minutes of each other, he promptly offered me a new phone. We both agreed that it couldn't be a hardware issue, but there was no other explanation. Cost me nothing, so I accepted his offer.
It came with 5.1.1. But I felt the need to upgrade to 6.0.1
And guess what? So far battery life is superb - I started with a completely 'virgin' phone ie no restore, no new apps, no icloud etc. and it was perfect. Then I gradually started adding the most likely culripts - iCloud (all options turned on), Google Latitude (background location updates), Facebook and Twitter (apps and iOS integration).
So far everything is still perfect - usage is increasingly slightly more quickly but that's to be expected with latitude and icloud doing background updates, but it's still minutes compared to the hours of standby.
I therefore very happy at the moment - assuming I don't suffer a relapse - but I'm left wondering what the **** is going on here? This must have been a hardware issue, but it can't have been because the hardware was fine with 5.1.1.
My only logical / possible explanation is that there may have been some latent hardware issues in a small minority of phones that have only been exposed by iOS 6. I realise how far-fetched this sounds, but what else can possibly explain the circumstances of when the problem arose and how it's now been fixed?

I had no problems with battery life in my iPhone 4S with iOS 6.0. I updated to iOS 6.0.1 yesterday and my battery life is much worse. Went from 100% to 80% on standby. Before the update it would have been around 95% or better. I'm not happy. Also, battery usage shows "Usage" and "Standby" as the same amount of time. That didn't happen before the "upgrade".

I updated my iphone 4S from ios 6 to ios 6.0.1 and the battery life is far worse than before. It really drains the battery at an incredible speed. You can literally turn on the phone and watch the percentage going down every few secs without even using the phone. I guess I'll just wait and hope a next update solves this. . And what's really sad is that the crash issue (which Apple has acknowledged )when moving icons over several pages is still not fixed!

I updated to 6.0.1 and... The battery drain on my 4S has more or less gone away.
In my case, Safari was the problem; whenever I killed it from the dock and did a soft reset, everything was fine. When I used it again, all **** broke loose. Now, after updating, I can use Safari without problems.
I don't know whether it actually was the update itself that fixed it or maybe just the process of updating... maybe it was just a corrupt file that got wiped out in the process. All I can say is that this time I updated directly on the iPhone via W-Lan and NOT via Itunes on my Macbook Pro - and that the update did not go smooth at all; I had to do two soft resets while updating coz iOS wouldn't load.
But now, at last, I am happy again.iPhone 4S

I gave up messing with it and got the new iPhone 5. My phone was old anyways. I wish Apple would explain what's going on and give some simple diagnostic tools as I don't have the time or skill to pour over the dump logs and only being able to see usage graphs when plugged into Xcode Instruments doesn't help much.
The new phone has been fantastic overall.
Changed to Verizon, due to some local coverage issues, and the fact that texts seem to come through fine with cell data turned off is a huge plus. Before, when I disabled cell data to get by, texts seemed to have unpredictable delays, sometimes people telling me about the message they sent before I actually got it.
With the new phone, it's super fast to quickly turn data off and on when needed. The first day I burned through 350MB, probably pulling cloud music and synch stuff, but then it leveled off, two days later being more strict, at 450MB.
Safari drains battery quicker than I think it should, but turning data on as needed and limiting safari usage is making me happy again.
When I have time I would like to figure out what the heck was going on with my iPhone 4, because the schitzo bouncing between fantastic standby, good for a week or two then sudden power and data surges that hit 10GB extra cell data I can't account for was maddening..
For the new iPhone, I set it up as a new phone, did not do any restores, and just linked it to the iTunes & cloud acccount to synch the contacts, iTunes match and other account stuff. So far so good and I'm crossing my fingers.

Solved the problem for me!!!
I had battery drain as well. I found, that it had to do with a broken bookmark in Safari replicated via iCloud to iPad and MBP. I could not delete it, because I did not know which of my > 500 it was and the iPhone always stated, that deletion is not possible because syncing is on its way. After Loading 6.0.1 i decided to set it up as new phone, exported all bookmarks on MBP to have a backup in case i miss a bookmark and then deleted all bookmarks on MBP.
I reinstalled all Apps via iTunes and had to enter all settings again, but today I had the 3rd day of battery with just 1 hour of talktime. Bluetooth on, WLAN on, iCloud replication for all items on, FB on, Twitter on. I did not switch off any suggested item, and the phone keeps running and running,.....
In case it reverts back to previous behaviour (just 6 hours until battery dies), I will report again.

Yes, Cellular data is on - as mentioned, I now have everything switched on.
Assumption: with a broken bookmark it trys to replicate again and again but never gets finished. I also tried to switch off sync, but it always connected to replicate "something". By removing all items via the MBP I got rid of the broken bookmark.
But be aware: if you just delete the bookmarks via MBP you will get the broken infos back if you do not reset your phone to new, because the sync will bring back the error!
