This might say more about the quality of modern apps than the power of the iPhone lol.
Example from a few seconds ago: I frequently click into HN user's profile pages when I read an interesting comment from them as I scroll past. At home, it loads ~instantly even on 5G. But when it takes 5-7 seconds to load one, you get a lot more thoughtful about navigating your browser.
There's definitely something interesting about intentionally downgrading your own experience in targeted ways.
