Swapping the battery means you save the carbon footprint of manufacturing the non-battery parts, which have a pretty high cost to all of us in aggregate that should somehow factor into the "is it worth to keep it going" equation. I wonder how we can make that happen.

My current phone is an S21 that's facing a plethora of failures (screen damage, flaky USB-C connector, weak battery, back cover delaminating) that are all individually fixable, but altogether I also find it hard to resist the pull of getting a new phone at that stage.

But I feel increasingly really bad about not trying harder to go repair-first. Also because there's otherwise virtually no tech/feature reason to "upgrade" from something as recent as an S21 these days.
