Yes, the price is relevant compared to the price of a new phone. And for what it's worth, the $120 price point only applies to the pro models, so your entry price is $900. But that aside, again I ask who are these people that are forgoing a $120 battery for a phone (one they'd be perfectly happy with if they could get a $30 replacement battery) in favor of a new $800 phone instead?
Yes in a hypothetical world where Apple charges $700 for a new battery, and a brand new iPhone can be had for $800, it's reasonable to think a good chunk of phones with degraded batteries would be discarded in favor of new phones. Likewise if we imagined a hypothetical world where iPhones randomly explode, killing the owner but only after it has been sold second hand, we'd also see a decline in the lifespan of used iPhones. But we don't live in such a world, and the batter replacement cost is not $700, or $480, or $240. It's $120 for two models and $99 for most others. And this $120 battery replacement world is the world the original commenter suggests that iPhones are becoming e-waste at a rate much more rapidly than they otherwise would if only they had $30 amazon replacements and sliding battery doors. It's the world where the original commenter implies that the only (or at least a significant) reason Apple designs the iPhone batteries the way they do is to drive sales of $1k+ phones. So in this world, who are the people rejecting $120 battery replacements for $1k+ phones?
