Two problems: an unforeseen problem that pops up after four or five years may deplete your spares. And ten days is not enough to restart a production line. On the other hand, if you overproduce spares to be on the safe side, then you are being wasteful when they don’t get used.
I’m not against requiring spares to be available for more than a short time, but this should have been thought through a bit more. (2/2)
@ArtHarg
then maybe it makes more sense for manufacturers to have common parts across models, and standardize more? Doesn't sound bad. There is no reason to have gazillion sizes of batteries and screens/digitizers. And that alone covers the vast majority of repairs. Also a well engineered device would simply last longer and require less repairs on average.
This mostly damages manufacturers of phones designed to be short-lived 👌
