Hello again everyone.
On page 8 I mentioned I had a problem with battery life and explained my normal usage habits with the phone. On page 11 i replied with the results of my first day after a DFU and new phone setup... running from 9am to about midnight on a single charge.. with some features turned off.
Today is day 2 of testing after a DFU... and... I turned all features back ON. There really wasn't anything left OFF to try and save battery life. 40-50% brightness and LTE / wifi on... blue tooth still off as i don't use it.
It's 1am now and i've still got 12% left... today had lots of texting, ipod listening, a few calls, and lots of email photo sharing, facbooking... and pretty much everything i ever did with my iphone 4...
It was a completely normal use day for me. And to check exact numbers, i reset the usage this morning when I unplugged it from charging.
Usage screen shows...
5 hours 34 min of usage
16 hours 1 min of standby
Call times were reset at 9am also
Current period 1 hour 3 min
Cellular data sent 38MB, recieved 62MB
anyways... i have a lightning cable charger at home, at work and in my car... i haven't even felt the need to jump up and grab one since i did the restore...
I'll be fine with my phone like this... for now.

This might be interesting. A free app that tracks just what is draining your battery. http://carat.cs.berkeley.edu/
It takes a week to produce a full report, but you can check it out from time to time to see what it has found out. We'll see.

I m using iPhone 4S. When I was in iOS 5.1.1 my iPhone battery life
Was awesome I was charging my phone every after 2 days i was using full time
Working perfect but when I updated to iOS 6 lol my iPhone 4S battery life
Goes worse every time I have to charge. If I charge full to 100% and if i use my iPhone for 30min my battery
Percentage go down very fast to 50% that's Ridiculous I fill to cry this iOS 6 really kill my battery percentage very fast
I tell you. I hope in next update apple should fix this Horrible Issue.
& Lets hope for best Result in next update.

Ok. i really think that the DFU reset and letting the battery cycle charge a few times does the trick. I took my phone off of the charger last night at 10pm before bed. I mistakenly left ten apps running in the background. To my amazement when i woke up at 6am this morning my phone was at 98%. When i left it off of the charger 2 nights ago and woke up with zero apps running in background i was at 59%. So it seems to have fixed the problem.

All of the iphones do not have problems. My cousin bought her phone on launch day and her battery has never once had a problem

Here's what i did. From Day 1 (last friday) i restored from iCloud and noticed the battery life was really really bad. So after starting to read online i did a restore from itunes, brough my contacts only over from iCloud and started just redownloading my apps. Battery life started out pretty good and then as i progressed through the day and into yesterday i was losing 2% just sending a text message. It was saying i had used phone way more then i actually did.
That being said last night i did a DFU reset and did not install anything, no email, manually added a couple contacts that's it. I let the battery die out completley. At around 10:30 after the battery was fully dead i plugged it in and did not touch it until this morning. I've installed three apps (facebook, twitter, pandora). I've sent a few text messages this morning and browsed the web a bit. I did not turn off anything, bluetooth is still on, location services, siri, spotlight, LTE, WiFi, all that is still on.
As of right now i've used a total of 25 minutes and been on standby 1 hour and 25 minutes and the battery is still at 100%.
So in conclusion it's either something to do with mail or some application that was installed. I thought at first it was the phone but i don't believe at this point it is, i'd say it's got to be a bug in the software.
If anything happens or changes i will advise back.

Or to add to this it could also be something to do with iCloud

can't rule out the manual conditioning of the battery either it seems

After the Apple store replaced my iPhone 5, my battery has been amazing. Yesterday I used it a lot over an 8.5 hour time and the battery was still 78%.
Last night I took it off the charger and while using it occasionally, I am at 8.5 hours standby and 1.25 hours use (video, Facebook, email, etc.) and 90% battery left.
When I had done the same thing with my old phone over just 4 hours, the batter was at 36%.... Over just 4 hours.
My suggestion is that if you're experiencing bad battery times to try to get it replaced ASAP. They already have replacement devices. Not a ton, but some.

I should add to my post that everything from wifi, push emails (15 mins), and location services to cellular, open apps (20), and notifications are on. And I received over 20 emails through the night. So nothing special is being done to preserve battery.

My phone too charges really quick, from zero (completely dead, phone died whilst in use) to full, not 100% actual full charge icon displayed in just under 2hrs..
I'm wondering.. with the rate a full charge is taking and the rate it is taking to discharge through normal use... Could it be an iOS bug that isn't actually charging the battery to full. I'm thinking the phone thinks the batterty is fully charged and shows fully charged however is maybe only 50% charged?
A theory that maybe true?
Could any technical people, or Apple Technical people reading this confirm that this could be possible?
It has got me thinking!

interesting theory! Never thought of that... it does seem to charge faster than my iPhone 4s or 3gs ever did. I've even noticed that if I check the charge percent (let's say it's 50%) then turn off the screen for a couple of minutes and then turn back on the screen I will visibly see the charge percent jump from that original 50 to a number like 60 in a short period of time.

There's definitely something in the suggestions regarding email accounts. I set up my new phone on Friday using the old 4 backup and noticed the same battery problems that everyone else seems to be stuffing. I deleted one email account (wouldn't send email) and reloaded it, and noticed a short improvement. However after reading a few posts on here about the possibility of it being related to emails, I deleted all accounts and reloaded them. My battery has lasted two days of normal use, same a my 4.
Having said that I can't quantify it because my usage data seems to have disappeared!
Try it, you have nothing to loose.

Adding to the anecdotal info:
So far I've done the Reset All Settings, Reset Network Settings, delete all email accounts, and the battery drain/charge cures and I can't say that any of them have really helped. I don't have specific numbers.
First couple of days the phone would drain insanely fast (could watch the percentage drop while staring at the phone). Seems to have improved a little but after another drain and charge cycle last night I left it simply sitting overnight and it went from 100% to 89% in the morning. I would not expect that much of a drop from the phone in standby doing practically nothing.
I won't do DFU because it's a p.i.t.a. and some have said it didn't help.
Considering trying to get a replacement but not looking forward to possible further disappointment :(

I just noticed in the Battery Usage screen under "Time since last full charge", 5+ hrs of usage, 11+ hrs of standby. I've touched the phone for all of about 5 min since my full charge last night. How did it get 5+ hrs of usage?!!
