Surface Pro 6 i7 1TB Battery Drain from 100% to 74% when turned off

I seem to be plagued by a battery drain issue with the Surface Pro 6.

Here is a quick rundown:

7/6/19 I bought a Surface Pro 6 i7 1TB. This device turned out to have a defective screen so I took it in for a replacement on 7/27.

7/27/19 I am assigned (what I later discovered was a refurbished unit) a replacement unit. A few days after that I started to notice that when I leave it at 100% at night, unplug it, go to bed, and when I wake up in the morning it would only have 74% o 75% battery left! Also when it is 100% and I unplug it, take it with me to work, by the time I reach my office about 45 minutes later then turn it on it only has 74 to 75% battery left! I was able to observe this multiple times. I tried several troubleshooting steps to no success. I am not using hello cortana face unlock or anything fancy.

8/15/19 I went to a Microsoft Store to ask them to take a look at the battery drain issue, and they said they saw nothing wrong and suggested I factory reset the unit which I did when I got home! But the following day the same issue appeared! 

8/16/19 I went back to the Microsoft Store and told them the issue has not gone away. They issued me a brand new Surface replacement. At last I thought that was the end of the issue. I left the unit charging overnight, and this morning it was showing 100%. Out of curiosity I wanted to find out if this unit would have the same issue so I turned off the device at 100%, unplugged it, then left it for a couple of hours. When I turned it back on the battery was showing 74%!!

At this point I don't even know what to do. If anyone has a solution to this problem please share, otherwise I have no choice but to make another trip to the Microsoft Store for a possible fourth replacement.

Here is the drop observed this morning - 

08:11:51 Suspended 100 % 47,150 mWh
10:13:56 Connected standby AC 74 % 34,960 mWh

    I experienced the issue both before and after updating to version 1903. I had hoped that 1903 would solve it.

    Hi, just wanted to update here that I have now received a second replacement from Microsoft for my Surface Pro 6 which showed the battery drain problem. I sent my original device and got a replacement. The replacement too had the same problem, so I got another replacement. 

    Question to all those facing this problem - Have you updated your devices with the Feature update to Windows 10, version 1903? Is it possible that the problem won't occur if I do not update this feature update and wait for it to become unavoidable? If yes, I am wondering if I should stay away from it until Microsoft addresses the problem.

    I am not sure about the hibernate. Because I set it to automatically hibernate after 60 minutes in standby. After that, I put my Surface to standby and turned it on again 2 hours later. Not much has happened then (3 percents lower power or so). But when I then put it into standby and turned it on again 12 hours later the power dropped by 25 percent. For those 12 hours, the Surface should have been hibernating for 11 hours, and still, the big power drop occurred.

    Not sure how does impact the battery, but I just realized that I did not noticed before this issue because I was not shutting down the sl2 but hybernating. If you hybernate, this “issue” is not happening. So I guess it’s something about visualization or such? Didn’t tested how much the battery last compared to shutting down tho...

    Having the exact same problem here with a Surface Pro (2017) i5 and a just newly arrived Surface Pro 6 i7 (Commercial Edition). After 12 hours my new Surface Pro lost about 25 percents while being in sleeping mode. I really like the Surface series, but this is a real reason for me to return the new Surface Pro 6 (especially as I am not sure if this can be solved with a software update). I even tried to reduce the time when the Surface hibernates (to 60 minutes), but this doesn't seem to help either.

    And I can also confirm that this wasn't always the case with my 2017 version. So somehow it seems like an update did this.
