Can anyone speak for iPhone 6S performance with 15? I'm on 14 currently and it runs quite smoothly. I assume it would be similar on 15.

I've been running the developer beta on the 6S since the beginning. Seems just fine to me!

Glad to hear it! Seems like not too long ago mobile devices were worthless after a few years, but those days are past.

I’m using a 6s Plus temporarily for a few days, and only installed iOS 15 less than an hour ago. So far subjectively speaking it seems about the same as iOS 14.8 was.
