I have bought MacBook Air i3 2020 last July 8 and after about two months battery health is showing 93 percent and the current capacity is decreasing every few days. the Original capacity shows 4381 where the current capacity is 4085. Is it normal? should I contact with the apple care centre?

what should be the best way to maintain good battery health?
