I have been noticing that when I shutdown my surface book, when I power it on the next day the battery has drained some. If I leave it off for a couple of days it will drain down from 100% to around 85% or lower.
I disabled fast startup... and then just decided to disable hibernation altogether. That didn't help.
I have windows hello disabled, but that shouldn't matter anyway since I'm shutting it down, not sleeping.
Some searching and I found a general windows 10 issue with the "Intel Management Engine Interface" driver. Some say that v11 can cause this issue. One solution that I have seen suggested is to go into device manager and in the power management tab for this device uncheck the option that allows windows to power it down to save power. I tried that and it didn't help.
Others have suggested downgrading the driver from v11 to v9 or v10, but I don't know where to get v9 or v10 of this driver that is compatible with the surface book. Anyone know if one of the downloads on Intel's site would be compatible?
So, has anyone else noticed this issue and know of a fix?

I have a Surface Book Pro (top of the line model, i7, 512GB SSD, 16GB RAM, etc.) and I love it, EXCEPT, the battery drains about 5-10% daily when it's shut down; not sleep mode or hibernate but literally shut down. I haven't seen a post like this however I have seen loss of battery when in sleep mode.
Has anyone experienced this? Do I have a bad battery(s)?
After 8 hours in hibernate after disconnecting, I was still at 100%. However 15 hours of shutdown left me at 96%. Odd, but it seems like hibernate is the best option for now.
FWIW, I left both a surface book and a Macbook 12 shutdown for a week. Today when I boot both up, SB battery is at 63% and MB is at 72%. SB is not as good but still reasonable.
Spoke too soon, the winner is a Dell XPS 13 (windows 8). Same week, 99% battery remains.

I removed sleep from the shutdown list, disabled fast start up, and set shutdown to happen for lid closing and the power button. Sleep is only an option for the sleep button, and I don't even know where that is.
I've been paying attention to battery levels from the evening to the morning and so far I haven't seen any more then a 1% loss overnight.
