    Hi guys

    installed the latest 10536 on Lumia 930 - Not a clean install. (Migration)

    I suddenly have massive battery drain? Device was fully charged at 7am - By 10am, i only have 40% Left, with average use?

    Were any of the apps updating in the back ground?
    When I first put 10536 on my L625 around 10 or so apps were updating for the first hour or so.
    Apart from the battery how is it running?
    I only ask as my main phone is a L930 but I haven't updated it yet as WP8.1 runs great on it.

    Try these:

    Press and hold the back button and close any apps you're not using.

    Fully power down the phone and restart it (press and hold the power button until you get the prompt to slide the lockscreen to power down. This will kill any rogue processes.

    Make sure you don't have any unwanted processes running (Bluetooth, NFC, etc.)

    Failing that, a hard reset would be needed.

    hello,
    same problem this morning with my 930, battery was drained in almost 6 hours.
    4G was off
    wifi on but not connected
    phone was only connected to bluetooth headset.
    now it's at 98%...i'm really curious if it will survive until tomorrow morning like the previous build. :)

    And 1 question... Do the apps which were available on wp 8.1 work on the wp 10 preview?

    Guys

    I am thinking its 930 related.......... as i searched a few threads, not alot of complaints of battery drain, but i saw about 5-6 users on 930 reporting. I have mine on battery saver 100% now, to just get through half the day...

    Check in this area:
    Settings > system > battery saver > battery use > change background app settings

    Under this you'll find which apps can run in the background; you'll see a lot of apps that you don't need still running and consuming power. I've only enabled core apps to be able to run like messaging and phone

    Try this and see if it makes a difference. There might be an app that consumes most of the battery by running in the background and you can switch it off

    I have quite an opposite experience so far with my L1520, updated from 8.1, no hard reset. I turned off NFC and Bluetooth, GPS is on. The device is cold, it was heating up randomly with 512. But it may be too soon to tell. 512 degenerated after a while and then problems started. I had to restart the phone then to get the overheating under control, I did not restart it for a while now, let's see how it holds up.

    I had the same issues, it is somewhat more resurce intensive than 10512.
    Anyways, try under battery saver to turn off Edge browser from running in the background, this helped in my case a lot!

    Also running it on my L930, but did do a reset... and have no problems at all. As a matter of fact, the battery life is much better than in previous builds in my opinion/experience. Took it off the charger today at 7 AM, and now (6 PM) I still have 60 % (with 4G and Bluetooth on). Of course nothing can beat the 8.1 battery life...

    Something in this build causes a background process to run 100% and kill the battery. Power off if this happens to workaround.

    I stopped most apps from running in the background that didn't make sense.
    Also go to extras -> touch

    change sensitivity to normal.
    disable double tap to wake
    and if you want to add even more saving disable vibration feedback from the navigation keys.

    My battery on my 1520 is actually much better since the update. I actually have been trying to wear it down. I did notice after the update there were app updates constantly running in the background. Since I turned off automatic update my battery has never been better.

    Hey guys, I don't know if someone already mention this before but I will tell you. Yesterday I was experience this batty issue either in my 920 build 10536. 3 hours after pull the charger, my battery running from 100% - 10% in 3 hours only. This is terrible.

    But I found some old ways to solve this problem. It use to work with old phone, but I tried this and it works. "Just try to put your phone to dead (0%/goodbye message) by keep using it. And then leave your dead phone without charge it for about 5-6 hours, maybe more (I don't know, I left my phone dead on night sleep). And then put it on charger BUT make it offline mode, or airplane mode so nobody can bother your phone. Don't use your phone until 100% charged and wait for more 1 hour still plugged in charger."

    That's it. My phone battery now last more longer than before. Unplugged from 2 PM and on 10 PM it still on 68%. A great battery improvement isn't it? Take a shot. Maybe this work with your phone too.
