Command
$ powercfg /batteryreport /output "%USERPROFILE%\Desktop\battery-report.html"

02What it does

The battery report records DESIGN CAPACITY and FULL CHARGE CAPACITY, so the ratio between them tells you how much of the battery's original capacity remains. It also plots capacity history and recent usage by day, which reveals abnormal overnight drain. It is read-only and safe to run at any time.
