I have an ‘old’ model (iPhone 14 pro max) and text frequently misses characters due to the lag/input delay. It’s most pronounced when using safari for some reason.
In any case, it’s odd that hardware is multiples better yet it doesn’t always nail something as basic as typing
In my experience, iOS only misses keys during the time the keyboard is loading (which can be over a second- crazy!)
But I often have input lags where I will press several keys, and then a period of time (which can be multiple seconds) will pass before my taps are registered.
The 14 Pro Max launched less than four years ago, and should not be slower than an Android which launched a decade prior.
