surface book battery drain while shut down

On my SurfaceBook i5/256/8/GPU model, I've been testing various battery drain states as well.  In my latest tests, I have "Fast Start" turned off, and I have been completely shutting down using the Start-Power-Shutdown option.

When my SB is docked to the keyboard and closed like a laptop, battery 2 (tablet) battery drains about 10% after 24 hours.  battery 1 (keyboard) drains about 5%.  This varies slightly each time I test.

When my SB tablet is disconnected and sitting no where near the keyboard dock, battery 2 (tablet) went down 0%.  I forgot to check battery 1 after this scenario, but I will keep testing.

But it sure looks like the theory of being connected to the keyboard has potential to being the issue.

I'm curious how your testing goes after you had your battery drivers reinstalled.  If it helped, also curious where she downloaded and reinstalled those drivers from.  Thanks

Tested again with the tablet detached from the keyboard.  Both batteries were 100% 24 hours ago, and after 24 hours of being shutdown and detached, both batteries are still at 100%

There is definitely something wrong when the tablet is connected to the keyboard as that is when it drains the battery excessively, even when powered off.  Can this be fixed with an update or firmware, or is this a hardware issue?

If you and I are running the same updates then there must be a difference in our hardware.  I have run the same test at least a dozen times.  My power options are totally at defaults.  I have changed nothing.  My Surface Book, i7/16GB/512GB, is a laptop and that is how I use it.  I use "sleep" during the workday and wake it up often using Windows Hello Face Recognition.  I sometimes go days without removing the clipboard portion.

Before powering down for the night I check both batteries.  Both are at 100%.

I power down by doing:  Windows/Start -> Power -> Shut Down.  I then remove the charger cable.  When there is no more activity and touching the touchpad does not light the keyboard, I close the lid.

In the morning, before re-attaching the charger cable, I open the lid, power up and check the battery.  I'm most often at 100% and occasionally at 99%.  I most definitely do not have a power drain problem.

I'm almost always connected to the keyboard.  You and I have something very different going on.

Gary, can you share how many hours typically pass between you shutting down at night and then turning it back on in the morning? 

I ran a test on mine last night, shut it down at 10pm when fully charged, then powered it back on at 7am.  So after 9 hours, the total battery was down to 99%, Battery 1 stayed at 100% and Battery 2 was at 97%.  Not near as bad of a battery drain as when I shut it down for 24 hours.

So if you ever get a chance to let yours be shutdown for 24 hours, I wonder if you would see the larger battery drain many of us are seeing.

I ran the test again last night.  I was shut down for not quite 10 hours and I was at 100% battery at morning boot up.

I can't ever remember shutting my computer down and not using it for 24 hours.  That just isn't going to happen.  The best I can do with my computer is not using it while sleeping!  ;-)

The bottom line for me is that I have no battery drain while my computer is off for the way I use my Surface Book.  I'm very happy. 

What I am waiting for however is never having to completely shut-down before I put my Surface Book in my courier bag or sleeve when going out.  (I use the Brenthaven Collins 13" Sleeve Plus and the Brenthaven Collins 13" New Courier Bag.)

I am happy to say that since the Dec 2nd update my Surface Book has run completely error free.  I absolutely love my Surface Book!

Yup. you're right.  Something very different.  Many people have same issue this person does.  Fully charged, power down like normal. 100% full when powered down.  Wake up, power up. Now at 89-92% most of the time.  

Says a lot about how pathetic this entire ordeal has been. .
