I haven't noticed having more I guess. The first day or two I definitely did, but I also switched to SwiftKey because I can now swipe on the lock screen with face id. Stock keyboard is pretty comparable to the 6 plus I used to have I think.
Less, and that's because I'm using SwiftKey as my keyboard. Word Flow isn't optimized for the iPhone XR and it was quite annoying on my old iPhones with typos and autocorrect.
Funny enough this is one of the reasons I am leaning towards an XR. With the bigger screen, I hope to not make as many typos typing with two hands. On my 7 I make so many it can be frustrating.
