My SP4 gets very hot and drains the battery very fast even though it is asleep. I found it very hot in its sleeve and down to 28% earlier today. Found it dead later in the afternoon. This is one of MANY issues this device has.
(My SP4 is not part of the insider program)

This isn't a solution as enabling hyper v on a surface brings up other issues, mainly with connected stand by.
On mine, with hyper v enabled, if the surface is put to sleep, once it wakes, WiFi doesn't work until after a reset. The only fix for me is to completely Uninstaller hyper v.
More details at the link below, and a fix that works for some, but not others

Guys, apologies if this has been mentioned but we may have a (partial) solution, as discovered by kevinmyexp on this Reddit thread: https://www.reddit.com/r/Surface/comments/417hwr/sp4_sleepdrain_suddenly_get_fixed_on_mine/
Essentially, for some reason enabling Hyper-V in 'turn windows features on or off' seems to allow the system to enter DRIPS, with no CPU C0 time. I tested this last night with a 3 hour sleep before hibernate and the system lost 4% battery with a drain rate of 550mWh. I am doing a longer test now, but for me 1-2% per hour is an acceptable sleep drain rate, considering my phone is somewhat similar. I have the 'stay connected to wifi' turned OFF for this also.
Something to note is that the first few times I tested this with a shorter sleep time of less than 30 mins the drain rate was higher. It seems that the system shifts into a deeper sleep after 30 mins or so. I am not sure of this though, and will keep you updated.
I heard from some sources that this issue is not from Microsoft, it is from Intel's Skylake chipset design fault.
I seems to be hardware related and cannot be fixed by firmware update. Only fix could be replace the Skylake chipset. I suggest whoever has SP4 which is still within 30-day return period do return the device and wait for a few months to buy it once the Skylake is mature.
This return period is not relevent if, in fact, it is a hardware issue that requires replacement. It would be a patent defect.
