Windows 10: Excessive Battery Drain by SoC Subsystems

My battery drains almost fully overnight when surface is in sleep mode. I ran the sleep report but don't really understand how to interpret this and what do you about it. Thanks for your help!

System Power Report - excessive battery drain caused by NoHwDrips.PMC_XHCI_ACTIVITY

Hello community,

I am seeking for additional explanation of System Power Report. My device (Dell Latitude 5285) in Modern Standby mode (S0i3) drains 2% (and sometimes even more) of battery per hour (>650mW), which is significantly more than Modern Standby compliant device should
consume. Report identifies "SoC Subsystem" > NoHwDrips.C10 > NoHwDrips.PMC_XHCI_ACTIVITY as root cause of excessive power consumption. I need additional info related to symbol/hook "NoHwDrips.PMC_XHCI_ACTIVITY" - which device / interface / process uses this
symbol, etc.

I have Windows 10 Pro version 1809 (OS Build 17763.1), most up-to-date drivers for all hardware. Please do not provide generic information on Power Plans, I already tried to tweak as much as possible (Fast Startup disabled, Always disconnect from network when
computer is asleep and on battery power).

I must say I am somewhat missing good old S3 Sleep Mode.

 

C6 battery drain too fast

i already done this steps still my battery drain too fast hope for other suggestions

 

Battery drains while on sleep mode.


even mine has a slow battery drain, using Win 8.1. Even when powered off, not in sleep or hibernate, but off. It still uses the battery to keep the clock going.
Turn off fast start, as suggested, hibernate over sleep as it uses less power, and if you aren't going to use it for several hours, shut it off.
