If I understand this correctly, it sounds like the issue is cosmetic, right?
If you don't mind, Can you go to this page: https://support.microsoft.com/en-us/windows/caring-for-your-battery-in-windows-2db3e37f-5e7d-488e-9086-ed15320519e4
Scroll down and find the section titled "Get a detailed battery report in Windows 11". Follow the instruction there to run the battery health report, and then share the report with me via OneDrive, or other cloud drive of your choice. I will review the battery health details. Thanks!
