macbook air 11.2.1 charging issue

after upgrading to the macOS Big Sur 11.2.1, My MacBook Air 2019 got struck with the battery 

it's not at all charging it will drain the battery after the usage but it won't increase the battery percentage after plugging into the charging port which I updates it to the 11.2.1 (latest update)

instead of fixing the charging issue it's troubling

thank you

A feature introduced into Big Sur was to preserve the number of Full Battery Cycles - there was an Algorithm coded into the macOS. It is perfectly Normal for Big Sur 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%
