You're confusing CPU and memory pressure, and attributing blame to the wrong component.

Android's lack of smoothness is due to thread contention, whereas the iOS kernel uses a dedicated UI thread running at high priority. RAM size has no impact on UI performance, beyond a sufficient amount for the kernel.

To add on to this, the person you are replying to is also quite wrong. Android devices definitely can be smooth and many go past 60hz now and have higher refresh rates than Apple products.

I don't care that the p90 UI latency performance is better, the p99 performance on Android devices is terrible (UI stuttering).

I use a Pixel 3 and iPhone 8 on a daily basis.

Agreed. I have a pixel work phone and iPhone (XS/12 pro) for personal usage. Even though the Android is also current gen it can be unresponsive at times and also the face unlock is terrible on the android. I can’t remember the last time faceid failed but on Android it’s atleast 2-3 times a day.
