iPhone 15 Pro Max Battery health dropping faster

On IPhone 15 Pro Max, I found out that on my phone cycle count only 31 count that battery health already dropped to 98%, and called to apple support, running different type of the diagnostics test, but saying working fine with my battery. Asking me continue using it, I called apple support is on 7-11-2023, and today 12-11-2023, I checked my battery had been dropped to 97% and just with 35 cycle count, mean that I just charged 4 cycle count already dropped 1%. And I checked apple community seem like this is the common issue on iPhone 15 Pro Max, but apple non stop saying this is normal…….. did anyone having same issue with me ? I think that apple still not taking any action on this issue, just will saying my software tested working fine with your battery…………
