My surface pro 9 keeps fully charging up to 100% by itself.

My surface pro 9 keeps fully charging up to 100% by itself. I use it usually connected with a power cable. Is it normal to charge to 100% of battery capacity by itself?  Some of the other vendor's laptops limit their charging to 80% for extending battery life. Does Surface Pro limit its charging to 80% under some specific situations?
