Maybe as a society it's better for people to have replacement insurance than to have sealed batteries that make phones so disposable. I wonder if we've defined IP68 as a "must have" without considering the alternatives. I'm thinking the percentage of people who actually "use" IP68 over the course of their phone is pretty small...yet that "requirement" drives a huge design choice.

I suspect it's a moot point. Makers have every incentive to drive replacement cycles.

Downvoted for daring to speculate. I love this place.
