Oh yes. Switched from the iPhone X to a 13 Pro only because the battery life became unbearable.

Overall, the size/format/handling of the X was *way better*. Even the camera was *better on the X* except in low-light pictures which I don't really care about. The difference is noticeable on 4K screens and print, pictures were truthful without complex image enhancement algorithms that you can't disable (even not in RAW). Etc.
