    I had a launch model cyan and it had very poor battery life. An 8 minute phone call would drop my battery over 20%. I turned everything off and hard reset the phone and it didn't help. On 11/20/12 I received my replacement phone and immediately performed the hard reset. The battery life is much better than the first model but I don't know how good it really is. I have 1 background app, and everything else off. IV had the phone off charger for 2 hours and I've done about 40 minutes of forum lurking, in stalled 3 aps took 2 pictures played 20 minutes of angry birds star wars and my battery dropped about 15 percent. Normal?

    Yes, I have noticed that game in particular drains the **** out of my battery, not sure why, everything else doesn't come close but ABSpace / Star Wars is insane.

    Was your LTE signal level very low during that time? When LTE is enabled and you have no or very low LTE signal level, it drains your battery real fast. It's a night and day difference for me. When I'm outdoors where LTE is strong, I only use 15% over 8 hours. The same phone doing nothing sitting at my home where I get little or no LTE, it consumes 40-50% over 8 hours.

    Apparently weak LTE signal is known to be battery killer on all phones.

    This may be a no brainer for some, but I realized this today: the back button is your best friend!!! After discharging my 920 a couple times I can usually make the battery last 12-16 hours (18 if i'm really pushing it) with moderate activity. However my phone went from 67% to 43% in 40 minutes today and it freaked me out, all I was doing was surfing on IE10 and playing Cracking Sands. Checking my background tasks I realized that I never closed the game when I went to surf on the phone. Definitely drained my battery. Hope that helps some of you folks.

    Nah, my LTE is very strong in this part. Even a weak single killing a phone over 2-3 hours is an incredible feat

    The battery gauge appears to be like a car gas gauge to me. Might go 200 miles on the first 1/4 tank, then 200 miles on the last 3/4 tank.
    I went this morning like 4 - 5 hours before it left 100% battery, then dropped 5% in next hour. I think maybe their are calculations off on it.
    I also noticed using the WP8 battery program, the only 1 day I had bad battery life, when i went to bed at 2 - 4% battery and woke up at 99%, it hadn't charged fully in 6 hours. I wonder if the gauge is off, when it shows 100% its not really full?

    The time remaining on the battery varies based on usage. It's always changing. If you go for hours without touching / using your phone and its actually in airplane mode, it will use up less juice. If you go from a day of not using your phone and then watch Super Troopers on your phone you'll be freaking out, man, when you see what % of your battery is remaining.

    FWIW, was on a long call while using gmaps pro to track my position. I had the phone in my car charger (cigarette lighter USB port), and the battery drained substantially. Looks like charging can't keep up in that case. The phone also got super hot, and this is while it's cold out. I'm pretty sure it will overheat if I try this in the summer.

    I was not talking at all about % or time remaining. The only number i'm looking at is the %full the battery is. 99% battery, 97% battery, 42% battery, etc.

    It depends on rating of the charger - this happened before with my HTC One X, Nexus S 4G and other devices. If the charger cannot supply a strong enough of a charge while the phone is in use your battery will go down. (Rapidly even)

    if you disable cellular data will you still receive texts?

    this is really pathetic that on a 2 week old flagship phone we have to disable every key feature "even if we r not using them" because of either poorly written os code or faulty hardware. such a disappointment. I know all devices go through this but it really sucks. my wife is on her 3rd iphone due to a bad battery and i had 2 at the time.

    What are you people doing on your phones that you get such horrid battery life?

    I guess having LTE on and that is it means having terrible battery life, or Nokia rushed these phones out without proper testing because they were already behind. they talk this phone up for months and this many people have problems?

    for our lumia 920's to operate properly we have to disable nfc,lte,bluetooth, all background apps.live tiles, then we must uninstall skype,nokia drive, battery thingy , plus deal with a lack of detail in the camera . So now im stuck with a sidekick ;)

    i just turned my phone off and it was at 60% i turned it back on and its at 56% ?

    I think that is a gross exaggeration of a problem linked to a small segment of Lumia 920 owners. Hey, I don't use NFC so its disabled. WiFi is on almost all the time as is Bluetooth for me because I've got an awesome headset. I don't sync with the cloud on Xbox Music and at most I'll play a game for eight minutes on my lunch break. Has my phone gotten warm? Yes. Hand warmer hot? Yes. I had Android phones that would do that. Have I since drastic drops in battery life? Well, yes. But, I was seriously using the phone. I'm not quite understanding the venom behind the comments regarding the performance of this device.

    you dont understand the venom? Nokia talked this phone up for months on end, never giving us any hard information on release and out of the blue they release this phone. Now people are having serious issues with this flagship phone, it seriously appears they rushed something with the release of this phone. Having batteries getting hot, draining in 3 hours, dust under the camera possibly because of poor build quality near the top of the phone. my charging cable is loose when plugged in, I should not be able to rock it back and forth while its plugged in. this stuff is inexcusable. We saw what happened when Apple rushed out their iphone 5, tons of problems. We should not be having issues like this as consistently as we are. Where is Nokia in regards to any of this? They messed up their promotion with the phone as well.

    Hmm, took my phone off the USB cord this morning at 7:30a. I've been browsing, watching videos, and playing games all day. Now at 41%...

    Btw - has anyone seen this video? Funny as heck: http://m.youtube.com/#/watch?v=-GjL1S82geo
