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)

Having this exact same issue, seem to be very wide spread.
Microsoft has lied about this...during the Surface Keynote Panos Panay specifically stated that the Surface Pro 4 and Surface Book have no battery drain during sleep, when it clearly is not the case.
Exactly the same issue here. Before TH2 I could get ~700mW drain during a 2 hour sleep session. And now I just got a 1600mW from a 5 hour sleep (I disabled hibernate first). This is unacceptable.
Most of the time the top offender is Intel HD Graphics, which seldom appeared in top 3 before TH2. The active time is amazingly stable around 15%. Besides, I usually have high activity from Marvell adapter as well and it is actually sending and receiving data. This is quite confusing since no matter how I change the related wifi settings, it still persists.
This is just a "Me too" post - SP4/i5/8G/512G, getting 11% drain per hour on sleep. It was about 5% before TH2.
My big offenders are WP sync and a USB driver (both 70% active, but not in the same sleep session), but the wifi, CPU and GPU are all in there as well at ~20%.
I've turned off connected sleep in the registry, so we'll see how that affects life later today.
As the official site in MSDN shows, a normal connected standby sleep session's charge rate should be less than 100mW.
