Can you provide evidence for your claim? Most people take this statement at face value and I don’t understand why. I do some volunteer work supporting elderly people that have issues adapting to a digital only world and I am always pleasantly surprised by the performance of their old iPhones all the way down to the 8 (old phones they get from their kids)
Also the coming iOS 27 release supposedly has some big performance improvements for all supported models that people have verified in the beta releases even with the iPhone 11: https://www.macworld.com/article/3160623/apple-finally-figur...
