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.

    And before I am faced with yet more requests to refresh the device- we've been through this with EVERY OTHER BUG and its quite clear from posts above that this will not help!

    AND NO, WAITING UNTIL SOME PATCH TUESDAY IN SEPTEMBER IS NOT APPROPRIATE EITHER..

    GET IT FIXED!

    I CANNOT BELIEVE I AM ON HERE AGAIN!!!!!!!!!!!!!!!!!!!!!!!!

    I'm on my second S2. After all the other ridiculous problems (BSOD on refresh, display crashes, drivers not updating, closing type cover causing standby drain etc etc, all of which the users here on this forum helped to solve), I am on here yet again to report yet another problem.

    What's the bet that this was somehow introduced from a recent update?

    Anyways, I noticed the other day that my standby time was reduced significantly c/w normal:

    Battery report today shows my estimated standby time prior to 17th July was regularly 280 hours or better.

    From 18th onwards its now 80 hours or less.

    Sleep study identifies the "unregistered device SE" active 100% of time during standby - sometimes with a tegra driver controller / marvelstar driver controller and "WU activator" (whatever the **** that is?).

    R eliability report shows a windows critical event on the 17th with thevideo hardware error at 20:00pm, timed exactly with the subsequent massive change in standby battery life.

    Essentially this confirms the causal relationship between the video hardware error -- unregistered device se --- standby lifeproblems., as I've never had this unregistered device se appear before.
