The only thing prompting phone replacement for me was battery life. And nearly all phones have shit ability to replace batteries (for now - EU rules incoming).

I bought a Fairphone 6 with /e/OS. I've left Big Tech behind. And I have a phone where I can easily replace the components. I don't want to swap devices for 4-5 years, which makes ownership far more cost effective than leasing.

Also -- with leasing, what happens when the renter is done with it? E waste, just like we have today.
