surface book battery drain while shut down

Hi, I just wanted to see who else has this issue because it seems like I've been reading about people having battery drain while completely shutdown, but they are always merged with posts that are mainly talking about battery drain while on sleep or hibernation.

I am one of those who are having battery drain on complete shutdown and it is very unsettling that after shutting down my computer completely I am losing 9~10% battery after 24 hours. This to me is a serious issue and I have brought this issue up with a technician through the online chat. I want to see if this issue is as wide spread as the drain on sleep/hibernation, because it seems that not many people shutdown their computers anymore and I am concerned it is easily getting overlooked as Microsoft only been addressed the battery drain upon sleep/hibernation.

Was your issue with the connected standby function or the issue that some Surface books still have battery drain when it is completely shut down? Or possibly both?

Today i lost 10% in battery life after having my computer shut down for 24 hours. Not sleep, not hibernate, shut down. I would show a screen cap of my battery report showing this, but I'm not sure how to on these forums. I just really hope this isn't an overlooked issue because I see a lot of people complaining about the connected standby but there are also users who experience battery drain upon full shut down

This was my case. A complete shutdown and battery loss of 8% in 24 hours.  Don't understand how that is even possible.  

I reported this issue to a tech over the online chat. Apparently the tech I spoke with said no one else has reported any issues like this. It makes me wonder if they are overlooking this issue and pairing this with the battery drain upon sleep. I actually mentioned this concern to the tech and they have created a ticket and told me this would be sent to one of their engineers. I was even provided a reference number for the specific case. 

I encourage anyone else who has the issue of battery drain upon complete shutdown to bring it up to a tech rep on the online chat. It would be a shame if this is an actual issue, but goes unnoticed because not many people "shutdown" their devices anymore.

Do a sleepstudy and you will see what happened.

I am not sure of the difference between "connected standy" and "complete shutdown."  What I have noticed on a brand new machine is invoking sleep and put machine in bag -- hours later it is very hot and battery drained down.  Not sure if this is also happening in sleep on my desktop on the charger -- how would you tell?
