iPhone 12 Pro battery health dropped by 4%

I have an iPhone 12 Pro that I bought in December. By August my battery was 100%, though in the last three months it has dropped to 94%. When I installed the new IOS 15 then it dropped by a whole 4%. What can I do or why is it happening.

There is nothing you can do. Batteries degrade over time, 90 percent is good. You should only consider changing the battery when it falls below 80 percent.
