Are you sure those half-second lags were there when it was new, or it’s just software becoming more inefficjent as usual, as newer models set a new performance baseline?
I don’t think any of the apps truly make an iphone from the last 4-5 years sweat at all - I would even question the “lag” parent commenter claims. It’s just probably a psychological effect of the new being better + promotion does make everything appear smoother.
