I just saw this thread. I have pretty much the same issues on my SP 2017 I5 256gb. Any suggestion would be appreciated.

- I just filed a report on feedback hub about the issues, but not sure how to generate a public link to the report. Here is the text...
"Roughly coinciding with a firmware upgrade in late 2018 (around Nov) for my SP5 2017 I5 256 gb, my battery has been experiencing significant capacity issues. A full charge lasts at most 3 hours on normal load (mostly spreadsheet, Word), which fluctuates wildly and has been decreasing. Percentage on the battery icon does not seem to correlate with actual capacity remaining. Sometimes, battery stays on 100% for an hour, but drops to about 60 or 70% in 20 minutes, after which the machine loses power without warning and shuts off without first going to sleep. Lately, batteryreport appears to be reporting random numbers for the full-charge capacity. Because the battery status is unreliable and the machine shuts off unpredictably, the only way I can use it now is to leave it plugged in. I have the latest firmware and system updates installed, but the problem only seems to be getting worse, giving me only about 2 hours on battery at most. The random unpredictability is the biggest issue."
