    Battery life is much improved.

    Before the update I'd be lucky to have 50% by the time I got home from work (off the charger at 7AM, home by 5:30PM) if I kept my usage to a bare minimum (light texting and 1 or 2 calls).

    For the 2nd day in a row (/since updating) I have 70% left and I've been playing games and messing with the camera off and on all day (9.5 hours since I pulled it off the charger).

    Noticed the same problem here. Glance on, double-tap off. Phone is in my pocket for the majority of the day and it seems like the L920 is smart enough to turn off the screen in there, since I can see the glance time pop on when I pull the phone out. Heat-sink is warm to the touch after not doing much of anything (checking WP7 News, checking 6Tag, few texts) and the battery seems to be draining like a leaky hose.

    Initially I was worried it was 6Tag, since that's really the only app I've recently installed (other than nokia smart and pro cam, which wouldn't impact this), but glad to see it's not. I'm trying the flight mode on - reset - flight more off plan, and we'll see how that goes. If that fails I'll try a 100%-to-0% battery drain, and hope that works...

    Cautiously optimistic!

    After the amber update my 822s battery life has jumped! 80% battery after a day at work.

    I'm having similar problems, Got the update from Rogers Canada, the first day I really toyed with my 920 so I can't say but by the second day the battery drained really quickly. After restarting the phone and charging to 100% I noticed the battery improved immensely. I managed 1.5 days of moderate usage. Something I never got out of my 920. By the third day onward the battery life has become worse. I charged it to 100% but within two hours it had drained to 74%. Even when putting the phone on the charger its taking and extremely long time to fully charge.
    Frustrating!

    I too have begun to notice some real battery drain lately. I got the update from Verizon. I am down 30% after coming off the charger this morning and I've done nothing but check email a time or two and receive one short call. I do not have anything extra running when I'm in the office, yet here I sit with 69%.

    Okay, so on a lark, I shut it down for about an hour. Turned it back on and charged to 100%. I made it through a day of moderate use and I was sitting at 86%. Didn't charge and just let it sit overnight and woke up to 79%. Don't have any explanation for this, but it certainly seems to have gotten better.

    Battery life here with 920 definitely improved. Before there was a steady decline of 3-5% an hour. With Amber about 2% an hour with use. Without use 2% whole night.

    Amber enabled 4G speeds and if there are no 4G masts in your area, your phone will waste battery looking for non-existent connections.
    Best to switch to 3G again if you definitely know you're not LTE-enabled - this could help save battery.

    From AAWP.com

    If you are on a non-4G contract (e.g. many of those on Vodafone and O2), or if you are in an area that has no 4G coverage (check coverage with your operator), you may improve your battery life by setting the "highest connection speed" to "3G" rather than "4G".

    In many cases there will be no difference in battery life (in theory your SIM card configuration should stop non-4G contract phones looking for LTE signals). However, it is something worth checking if your are experiencing poor battery life, especially after installing a software update (note that the Amber software update should improve battery by between 5% and 10%).

    this makes perfect sense. when i'm at home my battery last for days, I have an LTE tower almost in my back yard. when im at work I get about 1 day, LTE goes in and out 3g goes in and out and reception sucks altogether. still, overall battery life has improved with the update.

    Shouldn't being connected to WiFi help too? That's what I do when am home and still my battery life is not as good as it used to be. I've tried the soft reset and didn't help. Guess I'll try that flight mode trick next and see what happens.

    it's at 93% now after 6 hours 29 minutes, so I guess the flight mode did the trick ;)
    Dude you're a genius! That flight mode trick really works. I've noticed a big improvement today after trying it. How did you come up with that?

    What does this exactly achieve? Better battery life?
    If I understand correctly (which I probably haven't) you charge the phone, turn the airplane mode and then reboot the phone.

    Yes, better battery life. After the amber update some of us are experiencing a more than usual battery drain. You know what they say, whatever works!

    As much as I actually am a genius and would like to take credit for it, I can't... ;) I just read it somewhere, I think it was on these forums :)

    Let me make a small intro for my prob and your solution. :)

    I used my Lumia 720 for two weeks, and battery was flawless.
    Updated to Amber, still flawless.
    Then, i received three updates for "extras + info" , whatsapp and can't remember the third one.
    After that, drain began. Then i tried your method with airplane mode, and so far it's working like before.
    This is first hour after fix though. :)

    So, my question is: is your battery ok now?

    If it's not, i just pray that we all get Black update ASAP...and that fix will be included.

    Cheers!

    Glad to hear it worked for you too!

    My battery is absolutely fine. I think I've done this trick three times since I got my phone in May last year, each time was after an app update caused random drains. I have Black (since today) and hope it will be fixed forever, but if this is the only "maintenance" I need to do to my phone every now and then I'm fine with it, too.

    FWIW, my battery life has been improving over time, I haven't gone into battery saver for a couple of months now. I attribute it to some of the updates we have been getting. Still on amber here

    Thanks a lot! Couldn't agree more on that.
    And fingers crossed that Black fixed that forever. :D
    Btw, my battery is now on 90% after 3 hours of using my phone after full charge,
    and i used wifi for some time,watched video and got couple of phone calls and texted some messages.
    I guess that's ok. :\

    I think it's useful to know this:
    Battery worked perfect after airplane mode trick Joene90 told us (big thanks).
    Then,i uninstalled Angry Bird Roost yesterday,so drain happened again.
    Then i did airplane mode trick,and it's fine,but only when not using wifi or data connection.
    When using one of those, consumption goes up to 15% per hour.
    Will see what will happen after next charge,cause this problem happened between two
    chragings.
