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

    Is there a release date for this fix yet?  Glad there's a new SP7 but please fix my SP6 that I have had less than 1 year.

    It's getting really annoying that my battery runs out if I try to use it for more than 2 classes.  Also don't like seeing 74% battery after the device has been fully charged.  

    I realize the firmware has been released to some insiders but it doesn't seem guaranteed upon signup. Also, I would rather not take insider builds as I don't have time to troubleshoot or reinstall/reset my device.

    Not released to general public yet. It is only available on Windows Insider Program.

    Not official. Bugs free?
