Split from this thread.

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)

    You could disable connected standby - that removes the sleep option on the device, which means you're left with hibernate. Or you could set the time between sleep and hibernate to short time. Default is 2 hours. The 8% you see is consistent with default behavior, about 4% per hour. Sleepstudy will more than likely show 16% GPU and 12% CPU.

    Just to inform you, the regedit I did didn't remove sleep mode. I still have sleep mode...

    Yes, from an elevated command prompt (run as admin). What I did was add two lines to a text file called "power.bat"

    powercfg /sleepstudy /output "C:\Users<you>\Desktop\sleep.html"

    powercfg /batteryreport /output "C:\Users<you>\Desktop\battery.html"

    Save power.bat on your Desktop. Right click on it and "Run as admin". You'll see two html files (reports) saved on the Desktop.
