In what scenario? One that you don't have enough money for a nice phone so you buy a shit one, but you have enough money to replace it all the time?

Technically correct sometimes is not the best kind of correct.

What do you think most of the world does?

Something like "buy relatively expensive, not shitty phone, and make most of it"?

You really think developing countries are buying “expensive phones”?

Who do you think is buying the $70 phones in India, China, etc?

You really think its not?

Do you think no one in India, China ever buy expensive phones?

Is this being proposed as a solution?

Churn on budget smartphones is even worse than on premium phones and battery life is even more likely to be an issue on those budget phones. It's good for the budget market as well if batteries are replaceable.

It would be great if people could buy an old secondhand iPhone and replace the batteries themselves for $30-40 bucks instead of buying a $60-70 garbage phone with who-knows-what spyware and out-of-date software every 1-2 years. That companies are able to put out this kind of garbage and people are buying them is (if anything) evidence that the secondhand/repair market on smartphones isn't nearly as strong as it should be.
