I feel like the elephant in the room is that there's no phone battery that's going to stay useful in anywhere close to that time frame, and replacing phone batteries is usually a losing proposition. I've tried, several times. Fake, low-quality batteries are rampant (usually degrading within weeks), and genuine ones are prohibitively expensive -- usually a significant fraction of the cost of a new phone.

I don't know what Pixel replacement batteries cost, but Apple typically charges a flat $89 to replace an out of warranty battery, less than 10% of the cost of a new phone, which is a totally reasonable proposition if you think you can get at least another year out of your phone. Unless Pixels are dramatically more expensive, then this doesn't check out at all.

I think the point of the OP is that after ~5 years (when you have to change your battery), your iPhone is not worth $890 dollars anymore, but more like $200-$300, out of which $89 is a significant portion.

Not sure why you would consider the suspected re-sale value of the phone here?
From a users perspective the question would seem to be whether they want to spend $89 for a battery or $890 (maybe minus that re-sale value of 200-300, so still around $600) on a new phone.
