Battery Drains While Shutdown

Here is a copy of the sleep study.  It only goes back to the 31st.  I am finding it a little difficult to read since it doen't seem to show battery power at start up.  Yet, it looks like on 6-1 I was at 86% percent and had only used 5% batter power which would make me conclude it was at 92% percent at startup.  I had shut down the evening before at 100%.  I may try this evening shutting down at 100% and seeing what the percentage is tomorrow evening.

Hi Michael,

2. Press and hold or right-click and select Run as administrator.
3. On the Command Prompt, type po****wercfg sl****eepstudy.
4. Open the file location of the said report. (It will appear as sleepstudy-report.html)

NOTE:  On the  19th of the month I performed a complete Windows install (erasing my data files).  From 19 & 20 May, no apps, and no Office 365 was installed.  Nothing except Windows and all the updates.  I experienced a battery drain overnight on the 19th and 20th and each night I still experience a battery drain.  Below is the link to the battery report:
