If you look on Nokia's site for the changes in this update, they meniton that they changed how the battery meter works. I went ahead and drained my batter last night before I went to bed, charged it up over night and it seems much more accurate today and is doing really well battery life wise. The only anomoly I have seen is that I reset the phone after i uninstalled battery status (it stopped working for some reason after the update) and it lost 5% in the reset

I think I may have to many high expectations with this latest update pushed 12/18. I was hoping to see some major/noticeable battery performance with my Lumia 920. I will admit I am not the most smartphone saavy user however I do only have two apps running in the background
All others APPS are turned off for background tasks. That said, I do use my phone for web browsing and light video viewing. Place a few phone calls, send a few texts and check email. The battery still seems to remain the same performance wise. I have been monitoring these threads and am grateful for the amount of insight I find regarding tips on preserving the battery etc.
I won't go as far as stating my battery performance got progressively worse but I will say I think the battery performance did not change much drastically after the update/soft reboot etc so I will remain hopefull that it will get better.
This is my first LTE device with AT&T, had an iPhone 4 prior to my Lumia 920 so I'm not sure it's a fair comparison to state the iphone 4 battery performance was better than my Lumia 920 since one was a 3G device only. Not sure it can all be attributed to HSPA vs. HSPA+/LTE but it would be nice to have a somewhat better battery life. I still am happy with my choice to purchase the Lumia 920 and can honestly say I don't miss having an iPhone nor regret my decision to not go with Android.

I updated the phone yesterday and charged it completely. And since then, with decent usage, push mail for my Outlook, Hotmail and Gmail, push for Facebook and other stuff updating, I'm at 43% after 18 hours since last time it was charged. The update has improved battery A LOT.

If your mail service supports EAS then you "CAN" set it to check longer than 15 minutes and it should reduce battery consumption.. With EAS the https connection is idle unless new mail arrives .. the connection itself will reset after 15 minutes (might be longer now havent read the spec in a while .. Exchange 2003).
EAS was developed to compete with Blackberry.. which has PUSH email, not PULL (aka check every xx minutes) .. which EAS does with great efficiency and is as effective as BES from Blackberry. So.. point being if your services use EAS you can set a longer check but the battery gain will be relatively small.

As an addendum to this post.....
My battery live is SIGNIFICANTLY better after the update... although the only app I leave set to run in backgroud is weather (Nokia version). Three email accounts Hotmail/Outlook.com(as items arrive) , Yahoo (non EAS set to every hour) and Business Exchange 2010(as items arrive).
Before Portico with location service turned off (that thing was rough on battery) I would get about 18 hours on a charge with moderate use(mainly email, facebook, twitter).
AFTER the update I'm getting a ridiculous amount of battery.. with location services turned on.. obviously they fixed that. Right now i'm at 85% with 6 hours since last charge and it shows 22 hours remaining.

Update- 73% browsed ebay/amazon/twitterfor 30 minutes on and off and now my battery is at 59%. Is that normal. Everything is off, no background apps and its hot above the camera like it was on my first 2 models that had battery issues. I had this 3rd phone for a week and the only time it go hot was when I would wirelessly charge it

Assuming your phone is configured as you have said, then sounds like a bad phone. If you are in the mood for more experimenting, hard reset your phone, then update (assuming the hard reset eliminates the latest upgrades). If the hardware is bad, then out of the box you should see the same results. If not, then sneak back up on things to where you have it currently configured with apps, settings, etc. You just shouldn't have to optimize the **** out of things. I have a fair amount of apps but turn things on and off as needed and use hardly any of the battery. Just recently the phone lasted through a 5 hour plane ride and 3 hours of Nokia Drive navigation (flawless I might add).

Earlier today, I woke up from an overnight charge and played a couple games of wordament and browsed baconit for 10 minutes and my battery is at 79%. In 1 hour time, it drained 21% already from a 9 hour charge?!? I did a soft reset and it bumped down to 74% in 5 minutes. After 6 hours of little use (texting only), it is staying around 72%...I think the soft reset is a MUST after update. Its like restarting a computer, restarting always fixes stuff. However, I am still hesitant to say that it worked. To make sure, I will drain the battery full on this charge, and then wait for it to shut itself off and then charge it to full...maybe that will help my battery life.

I've been through 3 phones in 1 month and a crap load of hard resets. This is frustrating and tiring. It was working ok before the update. I know this issue was caused due to the software patch but at this point I'm just thinking about selling it or trying to get att to get me an android.im not saying android is better just saying I had an iPhone and don't want one and never had an androidso why not try it out and at this point what are my other option wait for another patch or deal with it.

There is a battery thread for literally every phone I have ever owned. I read all of the battery horror stories about the Lumia 920 before I got mine. If I had put stock in any of them, i would never have purchased the phone.
I have owned dozens of smartphones over the last few years and I have almost never had battery issues with any of them. Yet, I'll go into a forum and read a thread dedicated to battery issues and all kinds of people reporting how bad it is. I couldn't kill the battery on my Lumia 920 before the update. It would last almost as long as my Galaxy Note II with the same use. That's impressive to me.
I think it all boils down to individual usage and maybe some faulty units. I'm not saying some of you guys aren't having battery issues, I just think your usage is different than mine and in some cases, your expectations may not be completely realistic. The more you use a phone with a 4.5" screen and the more that screen is on, the faster it will drain the battery. Science.

I'm still trying to diagnose but i'm having this issue too...
before the update after the wireless charger I get maybe 1-2% drain per hr if I don't touch the phone
now it goes down at least 1% per 4-5 min. with idle no use.
if I start using it like I make one 15 min call and battery goes down like 10-15%...
I tried soft resets I uninstalled nearly every app except a few nokia apps.
disabled wifi nfc etcetc..
I don't know what to do next, maybe a hard reset... ?
bleh.. I REALLY wish there was a god damn process/task manager so that I can at least see whats sucking up cycles...
but no Microsoft doesn't allow apps that can access the system. like wtf. we need a jailbreak so that we can have those kinds of apps

Also kill any unnecessary background tasks if possible.
