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)

I experienced the high fan issue once. I restarted the device and have not seen this again. Your experience with a restart of the Windows Explorer process is interesting. I just restarted the Windows Explorer process and put the SP4 to sleep. I'll let it sleep for an hour and then run the sleep study process. I'll post the results when that is complete.
After my fan came on unexpectedly and no apps running, task manager showed quite CPU and quite bit of memory used by Windows Explorer process. I highlighted and clicked to restart the Windows Explorer process, and the fan immediately stopped. For the Windows Explorer process CPU dropped to zero and memory went down to under 20MB from about 130MB.
Maybe someone can test whether restarting Windows Explorer before sleep will prevent battery drain.
I'm not saying it's a hardware issue ... ???
I agree. That's why I said "If it is a hardware issue..." I sure hope it isn't!
I'll pulse my Microsoft engineer early next week. When I jokingly told him that I would do information picketing at the Microsoft Store where I bought it to inform others of this issue his response was "I would buy tickets to that." Haha...
