Not too long ago, iPhones didn't offer high refresh rate displays. Apple only switched to 120Hz screens with the iPhone 13 Pro in 2021, and only in 2025 brought its "ProMotion" tech to the base iPhone 17.
That said, if you've owned an iPhone for a while, you've probably noticed that not all animations feel consistently smooth. There are still quite a few places where the experience can feel a little choppy.
