    People keep saying that the WP 8.1 Developer Preview is in Beta and this is not true. The latest version of 8.1 is the official release. The only thing missing on the Nokia Phones is the firmware. And the only thing Beta is Cortana which is being updated on the backend not through the OS updates.

    I hope you can figure this out. I just had to hard reset my wife's 1520 because it kept locking up and was draining and getting hot. A hard reset and not using the back up has fixed it. Restoring the backup tends to just restore the problems in my experience.
    My newest findings:
    - Downgrading to 8.0 with Nokia Software Updater solved the issue. On 8.0 the battery drain was back to normal and no background CPU usage (phone was absolutely cold).
    - Restoring the phone (all apps and settings), still no problem
    - Updating again to 8.10.12397.895 and boom, problem is back with no app running after a fresh soft reset, around 1% battery gone every 2 minutes

    The work around for this is to Unpin Cortana. It happens on my 1520 as well. Phone get red hot too.



    I'm keeping Cortana unpinned until they sort that issue out.



    Just use the search button anyway.

    It's better now, but still not good (around 10% in an hour)

    2 days and 13hours with heavy usage it's fake. With heavy usage your phone will last for 6 hours maximum.

    Actually it did not work. I am loosing about 25% hr. I disabled all background apps.

    I did notice that if I turn OFF the data, then it cools down and goes back to normal.

    Dude, I've got the same issue when I updated my phone to 8.0 GDR3 preview about half a year ago. I was even wondering if it was a problem for products from specific distributors (mine was purchased in China, kind of a local type called 920T, modified by the stupid network operator here).

    I tried everything just as you did, and at last my rescue was to first roll back to GDR2, by using Nokia Software Updater for Retail, which did not solve the battery draining problem, but get my warranty and every information needed back; then I go to a Nokia service department, asked them to re-flash my 920T to factory defaults. That's when everything became normal again. It did not take long, each rolling back may take 10mins to 30mins perhaps.

    When GDR3 was officially pushed out, I accepted it with full preparation of having a same issue and having to roll back again, but to my relieve it turned out to be just fine.

    This time I became clever by holding back my curiosity and waiting patiently for a public official release. It's just why the battery issue appears to a certain number of products confuses me.

    Anyway I hope this might be of any help, and may you get your system back to normal again very soon.

    Roc

    i've terrible battery life with the latest 8.1 update. I noticed that my cell signal strength is low and switches often from LTE to 4G and back to LTE. I wonder if that's the cause.

    Hi,
    I also had this problem on my Ativ S, but I found a solution.

    1) Let your phone discharge to 50%-30% battery
    2) Download Battery Discharger: Battery Discharger | Windows Phone Apps+Games Store (United States)
    3) Do a soft reset by pressing Vol Up + Power
    4) Run Battery Discharger and let it discharge your phone's battery until it turns off
    5) Wait 10 minutes and connect your phone to charger
    6) If the phone is booted, do a soft reset again
    7) Charge your phone to 100% battery. Don't disconnect it when it has 100% and wait 2 hours before disconnecting.

    This solution worked perfectly for me! :)
    Another tip: Turn off battery saver, it will dry out your battery, because of a WP 8.1 bug.

    BR,

    Will give this a try

    I close everything I open. Unless there's another way of closing apps I don't know about.

    Hold Back button and swipe open apps down??

    go to app menu , battery saver , scroll down , show all apps , now you will be presented with a list of all your apps and which ones can do stuff in the background , you will be surprised that games like modern warfare are enabled to run in the background ;-)

    disable all apps you don't need running in the background in this list ;-) it may help apps from randomly starting on their own and keeping the phone awake ;-)

    Every app with the allow toggle is switched to not allowed.

    All apps bar 1. A day counter app that counts down days for a particular event.

    probably an app that doesn't play nice then? have you tried without any apps installed too see what drain % was an hour ;-)
