Thanks
MacBook Air 13″, macOS 11.6
Batteries are considered Consumable Products. Over time it will degrade to a point where it needs to be replaced. The usage is normal as the capacity will go up and down all the time and never stay always at 100%. Apple Batteries are rated for 1000 Full Battery Cycles and / or 80% Capacity before needing Evaluation or replacement.
For additional reading on Battery and Apple Computers this link may help. About battery health management in Mac notebooks and especially for the M1 and Big Sur & Monterey If battery charging is paused or on hold on your Mac
Depending on the Age of the computer, some aspects from the above links, may or may not apply to your computer.
A feature introduced into Big Sur & Monterey was to preserve the number of Full Battery Cycles - there was an Algorithm coded into the macOS. It is perfectly Normal for Big Sur , Monterey to Pause / Suspend charging the battery beyond 80% and hold it at that level. One can nudge / over-ride this by clicking the Battery Icon on Desktop Top Bar and allow charging beyond 80%. From observations, it will Pause / Suspend again once reading 90%. Same procedure to over-ride and will charge to 100%

You MBP Air does not qualify.
all MacBook Pro models released since late 2016 and the Retina-capable MacBook Air models released since 2018.
With the release of macOS 11.0.1 Big Sur see >System Preferences>Battery
