Yes I downloaded a third party app to install on my DELL laptop to show my laptop battery percentage on corner taskbar together with system icon.
I have filed a suggestion to Feedback Hub years back and noticed there are also many others suggesting for windows to add in battery percentage battery icon since it is widely used by many system date many years back.
I am just surprised a revamped windows 10 to windows 11 in year 2021 still using a battery icon without showing battery percentage. We still have to click on the battery icon itself to reveal the battery percentage.
