so far, i haven't noticed any performance issues myself. my phone usage is pretty minimal - i don't venture outside of iMessage, feeed, my insulin pump software, a couple of low-requirement games and Orion.

on the other hand, my coworker also has a 15 Pro and he complains that things are slow compared to iOS 18 for him.

I’ve an iPhone 16 Pro and it is definitely a noticeable slowdown for me, if you compare having “Reduce Transparency” on or off (which toggles most of the Liquid Glass effects).

As evidenced by the sibling comments, not everyone seems to be as sensitive to this.

Smooth, no performance issues for me, been using it since first public beta. I thought the whole liquid look was pretty meh at first, but I'm used to it enough at this point that I don't even think about it.
