I do wish upload was a bit faster as I push all my photos and UHD/60 videos to our Dropbox enterprise bucket! The phone gets hot too!
Wifi is faster and download/upload speeds are virtually the same.
XS/XS Max wifi radio while "only" 2x2 AC, is still faster than previous generation if by a little but it helps! 4x4 would be incredible. (but I think it would make the battery cry!) Even my Macbook Pro is "only" 3x3 and hits gigabit speeds (fast.com). The access points are 4x4 wave2 and have either 2.5 or full 10Gpbs backhauls.
