ELI5: Why are Phone companies improving screen resolution/size/aesthetics when currently the big problems with phones are battery life/low volume limits/poor reception/sturdiness?

Increasing battery life, volume limits, reception & sturdiness only appeal to users that treat their device as appliances. They buy new phones when their current product is obsoleted, more than a year after their last purchase.

The fashion user meanwhile will flock to the shop for the thinnest or newest phone just months after their last purchase. Same goes with spec-bragger that won't caught guard with less than 8K screen.

So you build your flagship to attract those who treat their phones as jewelry/specs check boxes, expect lower sales, frequent release, fat margin. Meanwhile from bargain components you build the middle or low end phones that will satisfy the majority of the market, anticipating their infrequent purchase and thin margin.
