And pretty much everyone in my family has used our android phones for 4+ years for as long as I can remember.

It's almost as if anecdotes are worthless!

Low end devices normally last less than high end ones. It's easy to forget that, as all iPhones were designed as high end, that phones can still be made out of cheap plastic and cost 200 bucks. Any android device in the sane price range as the iPhone will last at least as long. (And, for context, I'm writing this from an iPhone 11)

Oh sorry, this wasn’t an iOS-vs-Android dig, all the android manufacturers are constantly near bankruptcy, but apple has shareholders who are expecting growth, they will be hurt the most by consumers holding their on to their phones longer. (Samsung is reporting over 90% profit shrinkage, the Chinese brands are probably just PLA plants to capture as much communication as possible worldwide without a profit motive to begin with)

My dad is still using my old OnePlus one from 2014. Works fine for him. Using lineage OS. I know it doesn't get security updates but he's not stupid and doesn't use it for anything security critical anyway.

I'm way under 70, and I'm using an S10e I brought in 2019. So four years.

Updates stopped coming in March. But I've no plans to replace the phone yet. Since this one works fine, and very few phones released since have the features that matter to me.
