i have noticed it is much faster than the touted 30% on my XS. very impressive upgrade since i thought the 11's ushered in improvements via hardware (they still may have with better angles, etc.)
it also seems more reliable. i've found that if i have "attention required" Face ID gets a bit wonky on me in very odd shadow situations like evening in our family room with only a floor lamp illuminating the room, or if i have a bright window behind me. because of this, i have often turned off "attention required." this results in a faster, more reliable FaceID for me.
i should also say, i don't have much stereo vision so i think that might also create problems for Face ID.
yet, ios13 seems faster and more reliable so i have thus far been able to use "attention required" without any hiccups in the past 24 hours. we'll see if that continues. so far, with "attention required" it seems much faster than before and i daresay at least as fast as it was with ios12, with "attention required" disabled.
nice work apple!
