Or perhaps more positively, "e-waste production falls".
It's not surprising that the market would reach a saturation point; manufacturers are running short of ideas to improve their products, and even starting to resort to removing features.
Especially in the low-end/unbranded smartphone segment, I've noticed newer models aren't actually getting better. Several years ago they practically all had removable batteries, microSD, dual SIM, and a full complement of sensors; now it's nearly impossible to find such a complete combination anymore --- they're all missing one or two things.
