To the question of: "What is the difference between a phone from 2015 and a phone from 2025?"
The answer is: Nothing. Tell me one thing you couldn't do with your 2015 phone that you can only do with your 2025 phone.
"oh I can't install this app on my 2015 phone anymore"
That is artificial obsolescence, 99.9% of apps could work on that phone if they hadn't been made artificially obsolete.
However there is one thing phones have "improved" at: Stealing your attention.
Seriously, think back and tell me, did you use your first smartphone as much as you use your current one? Did you use to do as many things with it as you do now? social media, watching videos, listening to music, web browsing, chatting with friends, checking your bank app, paying with your phone... and that's just the most "common" stuff.
The reason why phones haven't changed that much is because right now the "better" phone is the one that can steal as much attention from you. And you dont need fancy tech upgrades for that. Just a lot of social engineering research.
