I�ve been trying the beta on my phone and I have to say that performance is great.
My iPhone 6S has always been a machine all this years, performance got better after iOS 12 but I�m glad this year Apple is following the same optimization for old devices.
I�ve been thinking about changing to a new model (maybe 11) because of screen size and because I like to buy new stuff haha.
However, if the phone keeps working like this I will stay another year. For me it�s the best design, thin, not heavy and tbh new iPhones (besides the camera and performance) do not offer a lot to justify the 1300$.
Anyway, Congrats to everybody that worked on this release, it�s good to see Apple caring about old phones
