Hello Karen and the thread,
I also am having the same issue with my battery as described in this thread.
My battery was not taking any charge at all - So I factory reset my Pro4 and did the generic Windows update and it started to charge. But then it stopped again. So I followed the steps of un-installing the battery drivers via Device Manager and doing a hard reset and my Surface Pro 4 is charging again. But it doesn't hold charge when shutdown (via the Windows Icon in the bottom left hand corner) it will go from 100% to flat in 24hrs - when Shutdown.
I am now following the steps for downloading the drivers and firmware you mentioned above and hope this fixes the issue.
I read on another thread copied and pasted below:

After doing some research online I found two possible solutions:
1- disable "connected standby"
2- disable Intel Management Interface
I tried option 1 first. 100% charged when I went to bed, I turned it on after 16 hours and 0% drain (yeah I'm happy now). That seemed to be the problem. It is obvious that the Surface doesn't really turn off with "connected standby" on. It takes 2 more seconds tu shut down and another 2-3 seconds to start up which is great because it is still super fast when you turn it on so that's "problem solved" for me. What a silly feature, to be honest, pretty useless considering how fast the device is.
I think I'm gonna try option 2 as well with "connected standby" on to see how it goes. I'll get back here if I do to tell how it went.
I hope this helps other people.

Is "connected standby" still a thing in Windows 10? This was quite an old thread from 2015
Thank you for your time in this matter and I hope you can help.
All the best, Steven
