Battery drain with Unregistered device SE?

Hi all, 

Lately I've been noticing a large battery drain (at least by my standards) of ~1-2% per hour during connected standby. Based on what's advertised (7-10 days idle) I'm getting ~4 days at best? I ran the sleep study, battery report and energy report and came up with interesting results. I've also calibrated the battery and have no current pending updates. Any ideas as to why the large battery drain during standby? 

Also sorry in advance for the long post. I'm not sure how to post the full reports on this forum.

    I have same issue

    Refreshed surface and the unknown device se was gone...

    Then installed the whole bunch of updates and latest firmware and its back

    Its amazing every time i have issues with my surface it is software/driver related.

    Last time it was the drivers not updating after new firmware

    When is Microsoft going to release reliable drivers for this device?!?!

    seriously

    I cannot understand why Microsoft is unable to tell us what unregistered device se is!

    I have the same problem, and obviously it cannot be fixed by replacing your device. I also refreshed my device, didn't help. It shouldn't be that hard for MSFT to fix this..

    Mike,

    I ran the prompt above on my surface 2 a while back and it didn't make any noticible change in my standby time. At this point I've accepted that my standby time will not be advertised and have resorted to turning my surface off whenever I'm not planning on using it for a few hours. Not ideal but it works.

    I have just send mine in for replacement, didn't want to wait.. and just as I had UPS pick it up, a techsupport just called me with a possible solution that you guys might find helpful.. since I wont be able to test it!

    So here you go.. this should remove the Unregistered Device SE, according to the techsuppoerter:

    Step   2: In   the search box, enter  command prompt .
    Step   3: Touch   and hold (or right-click)  Command Prompt to   bring up the context menu. Tap or click<br>Run as administrator .
    Step   4: On   the  User Account Control dialog box, tap or   click <br>Yes .
    Step   5: At   the  Administrator: Command Prompt , enter the following:<br> <br><br>  powercfg -setdcvalueindex SCHEME_CURRENT 19cbb8fa-5279-450e-9fac-8a3d5fedd0c1   12bbebe6-58d6-4636-95bb-3217ef867c1a 3
    Step   6: Then enter  <br><br>  powercfg -setactive scheme_current

    Did this work as suggested?  This fix was originally published to address a network adaptor issue for those who updated from 8.1 Preview to 8.1.  Shouldn't be an issue for anyone who updated from a refreshed device.  And haven't we all at this stage!

    Surface RT only: Battery issue when updating from Windows RT 8.1 Preview

    If you updated Surface RT from Windows RT 8.1 Preview to Windows RT 8.1, you may notice a decrease in battery life. During the update, the wireless adapter power policy isn’t migrated. Instead, the power policy is set to a default value that consumes more power both during use and in the connected standby state.

    I'm wondering this as well. Still seeing loads of drain by this unregistered device in the logs, sometimes its as much as 16% a hour. Making my reports showing 30-56h of stby time max.

    Here's some images showing it in action:
