Ask HN: How can old phones be slower while doing basic tasks?

I just got a new phone after 4 years (iPhone x to iPhone 13 Pro). And its mind boggling how much faster the phones opens Apps etc. But I ask myself, why? I mean, web browsing, open spreadsheet apps etc. Did developers become so lazy that they don‘t really optimize anymore? A phone created this year should perform the basic tasks as well as in 5 years, shouldn‘t it?
