Don't wait for Microsoft — here's how you can see your battery percentage on Windows 11

Microsoft recently announced a feature that will add a battery percentage icon to your taskbar, something that many would have liked to see years ago. The feature is currently in testing with Windows Insiders, and it's not known when it will come to general Windows 11 releases.
