i5/256 Surface Pro 4 overheats and battery drains while 'sleeping'

That isn't hibernating. It is constantly awake. Hibernate takes all the information in memory and saves it to the SSD and then shuts down. Yes, the PC completely turns off. Therefore, it shouldn't be waking up AT ALL. Something is fishy. 

Do you have hibernate enabled from the start / power button? Have you reconfigured the buttons to go directly to hibernate? I have my my power button hibernate, and close the lid to 30 min sleep (just in case I want to wake it up very quickly, like from moving from the living room to the bedroom, or to the table, etc), and then hibernate after that.

There seems to be a problem that the surface pro 4 is draining battery while hibernating. By definition we should see 0% battery drain while hibernating. My surface pro 4 i7 16 gb drains roughly 5-6% overnight while hibernating. I am positive it is under hibernation and not sleep. This is something other users are getting as well, as you can see in this battery report thread, or the below imgur link. 

Can anyone give any update or advice to this issue? While there are already multiple threads about sleep problems, it is very concerning that battery has any movement at all when it is hibernating/turned off.

I had opened a support case for the SP4 sleep drain issue with Microsoft on 11/21/15.   Today I checked the status via chat and was told that my SP4 needed to be replaced.  I queried the agent about the firmware issue and was told that "a number of units" had this issue and that Microsoft is working on the fix but my unit needed to replaced.  They were emphatic on this point.  So I made arrangements to get a new one from the Microsoft Store where I bought it rather than wait the 3-5 days for Fedex and then return the "defective" unit (all free with no credit card required).  Oh and I was told that the support center was informed of this issue impacting certain devices on 10/27/2015!

I returned the unit to the Microsoft Store.  Store tech support confirmed that this was a firmware issue that they have seen a number of times and that Microsoft support was working on a firmware fix.  They did give me the disclaimer that I might see the same issue on the new unit, but that it would be fixed with the update in work.  Of course they gave me no date for this.  They also confirmed that the Surface Book has the same issues.

I now have the new unit.  Upon set up it ran one quick update.  It is now running build 10240.  This initial sleep session (55 minutes) after charging showed near-zero battery drain (WiFi off during sleep).  The CPU0 Time had a 1 percent active time and the Intel HD Display was not even in the report, both good signs.

So far so good.  I had set Windows update (via policy editor) to not automatically download and install updates and do not intend to manually update until I see progress on this issue in the forums.  I can get Windows Defender updates manually from within Window Defender.  And I can live with the occasional display adapter crashes or whatever issue that are fixed with other updates.  Oh and the unit is very cool -- no hint of overheating.

FYI the display adapter driver is dated 9/24/2015 with version 10.18.15.4293.  The battery Microsoft ACPI-Compliant Control Method Battery is dated 6/21/2006 (yes 2006) with version 10.0.10240.16384. 

Any thoughts?

Same problem, interestingly enough, this does not happen to me if you put to sleep after a reboot (at the login screen)

I have the sp4 i7 512 fully updated as of today and am losing ~18% battery per hour of 'sleep'. The biggest offender is Intel Iris Graphics 540 (\_SB.PCI0.GFX0) at 84% of active time and CPU C0 Time at 59% of active time.

For a high end device this is pretty terrible:
