I am also getting great battery life - phone easily lasting a full work day - not even going under 60%. On 3G, wireless, syncing emails and facebook but seems to last really well. I did notice on my Lumia 900 and 920 once you use Nokia Drive it start heavily using battery life - if you wanted it use it for any extended time really need to be plugged into power.

Had mine for a week and I started off by completely draining the phone ie start it after it shuts down and after that charge it fully. Did that 2 days in a row to make sure it was all synced up between battery and OS. Having great battery life. Last charge had me at 40% after around 27 hours with normal use (no music though). Right now I've been off the charger for almost 6 hours and im still att 98% after some email, texting, app downloads and a 10 min phone call, I expect this to go down quickly now that I will start listening to music though.
Wifi always off except if I need to upload a picture to skydrive (I do everything on LTE)
LTE always on
1 email account on push (receive 10-20 emails a day and I send a few)
Battery saver off
SMS backup off
All feedback/send information to MS/Nokia is off

It happened again. Monday my phone was perfectly fine. 100% charge. Went through the day only texting and not much else. Battery was perfectly fine Tuesday as well near full charge. Went to bed Tuesday, woke up today and the battery was down to 28%. Checked my email and 30 minutes later its down to battery saver level.

My 902 loses ground even when plugged in when watching netflix or using drive. I had my phone go dead twice while trying to navigate last weekend with it plugged in. starting at half charge about only made it 1.5 hours through a movie. Anybody else notice this. That seems crazy to me.

I've read about the drain even when plugged for nokia drive, i find that ridiculous.
Haven't read anything regarding watching netflix though, i would that ridiculous as well, those should not happen when your phone is charging.

No matter if your battery is very good or bad, GPS nav apps will demolish it very quickly. This phone is very inefficient when it comes to sat nav. None of my previous phones - iPhone 5 or Galaxy S2 was using so much battery in so little time, when using sat nav.
In fact, it uses around 12% in 20 minutes which is a bit ridiculous if you ask me considering, that my screen is set to auto with min as a preset...
I am a bit dissapointed with this phone when it comes to battery life and my battery is fully settled after 2 weeks of use. I have no battery draining problem, though.

I have great battery life, Wifi on, NFC on, Email sync always on, high sensitivity on, brightness auto, facebook tile on, few news site active tiles on, weather tile on, everything on, so i have not made any compromises.

I was having bad battery life, (as you can see about 1-2 pages back a post i made a few days ago here). I downloaded the battery discharge app from the store and let my battery die 100% over night to the point where when i woke up i couldn't turn the phone on at all.. I took the phone to work with me at 8 am and started charging it there... at 1 pm i took the phone off the charger at 100%.. i have used moderate use.. texts, phone calls, games, web browsing, used the camera.. I showed the phone off to some friends last night at dinner so they were playing around with it.. I do have NFC off and my email updates every 2 hours, and bluetooth is off. I have wifi on and using 4G LTE. Without having recharged it, i am at 41% battery left and it's 8 AM the next day.. so not a full 24 hours yet technically but it seems like it may last until then.
It says it has 1 day 9 hours left but i don't know how much i trust that evalutation...

I just tested Nokia Drive on my 808 and it averages around 150mA .. the GPS receiver and the app are running, but I am standing still so.. I don't know if that makes a difference. Will test later

Yesterday, I used my 920 for 30 minutes straight and the battery dropped 10%. Last night I worked on my iPhone 4s for 30 minutes straight and it dropped 10%.
I would guess for a non-defective battery, this might be normal for a smartphone. Not scientific, of course, and your mileage may vary.

I have done little experiments on my 920 and identified some apps that drained my phone battery. What I did is installs an app one-by-one and monitor heat and battery usage. These apps heat up my phone IMMEDIATELY after installed and the heat was gone after I uninstalled it.
Nokia Drive + (well-known battery drainer)
Facebook with toast notification (without toast notification worked fine)
I'm not claiming this as a fact and it might be unique only to my phone.

Draining for me was whatsapp which i eventually removed and for some odd reasonj imgur uploader. This app doesn't even run in background, once i dled, it drained the **** out of my battery on standby like 20% in 1 hour. so i removed, battery back to normal.
I have battery status, paper shuffle and weather running in background 3 emails with one as it arrives

My 920 battery just doesn't last very long compared to my wife's 920. It doesn't matter what my settings are or what apps I have installed. I can turn everything off and she can have everything on and her phone will still outlast mine everytime. She actually uses hers throughout the day for her job, and I don't. Both are white and purchased at the same time.

This is normal for me, and somewhat sucks.
Bluetooth = OFF
NFC = OFF
WIFI = OFF
Brightness = AUTO
Touch = OFF
So far today:
6 Received Emails, 1 Sent
20 Minutes of Streaming iHeart Radio (1310 The Ticket)
15 Combined minutes of Internet
Amazing Weather HD
The Daily Beast
iHeart Radio (this comes back on each time I use it)

See if you can get a replacement unit.
Early in this thread I complained about my batter, did this..did that...sold my first born for $1 and nothing helped the battery life!
So I sent my unit back...got another one and I been happy (relatively) every since
A few days ago, I read a MS/Qualcomm engineer talking about how the wifi being on had very little effect on battery life and I poo-poo'ed it because this thread is filled with advice about turning everything off. So I figured I just leave my wifi-on to prove him wrong and guess what? The affect on my battery life was negligible. This was an unscientific test of course, but I had expected my battery to be drained after 8hrs of being on looking for a connection. I have wifi at home but not during 8hrs of work + commute times
I only searched b/c my cousin just bought her a 8X and I was testing out her Data Sense app as I don't have it on AT&T and I was surprised that she only consumed 38MB in 12days. So I asked her how is that even possible and she told me that she just left her wifi on all the time. From there I just started googling about the power consumption of the wifi chip and...
I say just get another unit if possible as the quality control in somebody's department in not up to speed.

Just wanted to say, I called AT&T Warranty Support and after about twenty minutes, I had a replacement 920 on the way. Three days later, I had my replacement and after a few days of use on it I can say that the difference is night and day. Excellent battery life, easily a day of use if not more on a single charge running the same apps, Bluetooth disconnections don't cause it to reboot, and the volume controls work as expected. It's literally like a new experience all over again. I definitely recommend calling and getting a replacement if you're having to charge your hone throughout the day versus waiting for your local store to get your color of choice.Microsoft Store employee; opinions are mine.
I'm on the Twitters.

I just hope Nokia and MS are paying close attention to what's going on here. I had yet another rapid battery drain this afternoon. This after the first time I've actually used Skype in weeks. (I may have used Facebook, too, but I'm not sure I haven't used it at other times in the past couple of weeks.)
It is just plain wrong for users to have to sift through the options and apps they have installed and turned on to ferret out the cause of battery problems or any other device problems for that matter.
Nokia and MS should be very vocal about what is going wrong and what THEY are doing to fix the problem.
but . . .
Kudos to all of you who are making the effort to figure out what the root problems are.

While they sort out the problem, people might try rebooting their phones if they see faster than usual battery drain in progress. Don't just watch it drain helplessly. It's not a permanent solution but it might unwedge things so you can avoid getting stuck with a brick early afternoon.

I've created a plot of a typical day of battery drain during the work week for me using the 'Battery Tile and Log' app. There seems to be an issue when I get home that drains the battery very quickly. If I turn Airplane mode on, the drain stops. There's obviously something going on with the radio or wifi. NFC is off. I usually get no LTE at work so maybe that has something to do with it. No background tasks besides Amazing Weather and the Battery app and I wasn't using the phone at all during the drain. I also notice my location symbol is on a lot. It was even on when in airplane mode. I'll try to further figure out what's going on this weekend by selectively turning off services during a drain.
