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.

    Agreed. I've done this as well and I'm still seeing the same result with the unregistered device.

    Where did you notice the NVidia Tegra Audio report? Was it part of the sleep study? I'd be interested in finding out if mines says the same.

    Noticed it in the energy report, at the top. Only saw it at random times.

    Looking at my notes for a now exchanged device I saw no mention of the SE device at first (near out of box) when I ran sleepstudy.  Then the usual Hardware Video error showed up in Reliability Report and from then on the Unregistered Device was listed in sleepstudy reports.

    I think this is all connected to SoDs, 327.67 errors, the SE device and Tegra drivers and/or hardware.  We'll never know for sure.
