>who in the world needs all this replacement batteries anyway
>I'm still rocking a 13 Pro purchased when new
Congratulations, your phone with a whopping 2-years of age still has a good battery. (Though I'm not sure losing 60% a day is really great imo...)
Try living in a world where a $300 phone is a big expense, and now it barely lasts a day when it used to last a week.
1: Some people have phones that are just fine, but have a dying battery. Replacing an otherwise perfectly functional phone just because the battery is going is massive e-waste.
2: Not everyone can afford constantly replacing their ever-more-expensive phones just because the battery died. Even if they can, it's a really wasteful use of money.
Consumers should have the choice. They can get a product with some compromises, but a replaceable battery - or a potentially more durable, more waterproof phone without one.
Of course they don't bother because the demand is a vocal minority. Most people don't care. But the e-waste effects everyone so something does need to be done.
