My iPhone SE 2020 battery was around 85% with 3.5 years of use when I upgraded to regular 15.
Now my 15 already lost 1% battery within one and half month of use.
Same thing happened with my brother. He’s 12 is at 85% in less than 2 years of use.
So, maybe newer iPhones have weaker batteries compared to older ones.
