iPhone Battery Capacity
Battery capacity of iPhone 11 Pro Max has been dropped to 97% within three months from the day I bought it. What should I do? Is it normal?

That's pretty normal for 3 months. Apple's nominal rating is 500 cycles to 80%. If it's simplified to a linear decline, that's 1% every 25 cycles. Maybe a little bit higher decline than average, but Apple isn't going to do anything about it unless there's a performance issue (like an auto shutdown from a voltage drop) or if it's under 80% under the warranty period.
