I understand the sustainability concerns but what is the answer? More regulation from the government that would impact their designs? That doesn't sound right, I don't think there are smart phone designers working for the government. I have replaced screens and batteries on iPhones, it isn't wizardry but does require technical acumen and some special screw-driver/pry tools that won't break things. It isn't an open standard like PC parts but there are lots of other industries that are mostly closed and engineer their products to only last a certain usage threshold. Engineering them to last longer costs way too much.
