Not really, modern phones have fast charge capability that's been improving generation over generetion, so what happens is new chargers are bought to take advantage of that. The older gen chargers are E-waste either way, and apple gets to charge us for something they should have included.
USB Power Delivery has been pretty stable; even my oldest charger, bought in 2017, is capable of fast charging the latest iPhone and Android devices – except for those exclusively using some proprietary "fast charge" crap (which is strongly discouraged by the USB-C specification).
Older gen chargers didn't just become e-waste suddenly because newer bricks that support faster charging are available. I've still got a couple of the 5W USB-A bricks sitting around that I like for slow-charging devices.
Not that I endorse cutting more corners, but I personally gave away the 30w dual USBC charger that came with my MacBook Air since I already own plenty of higher powered ones that work with other devices like my work MBP and Nintendo Switch etc.
I think it'd be great if Apple offered a small discount for opting out of unnecessary items.
iPhone fast charging hasn't really changed over the years, it's still only 25W max, which can be satisfied even by early USB PD chargers.
Androids have their fancy ~100W fast charging where all of the charge controlling is in the brick for thermal reasons and those require special proprietary chargers that become obsolete after a generation, but Apple doesn't do that.
That doesn’t mean they have chargers that meet the wattage and port needs of newer phones. I still use an iPhone XS Max, which uses a 5 watt usb a charger. If I upgrade to an iPhone 15 I will need to get an usb a to c cable and the phone will take forever to charge. I don’t even know if that wattage is enough to charge the phone while it’s on, especially with the pro models.
Or they could just include a 20 watt usb c charger with my $800-1200+tax and activation fees phone and not force me to spend another $60 on their power adapter. though to be fair a third party option would certainly be less expensive.
It’s amusing that you’re getting downvoted when that was the entire point of forcing Apple to standardize on USB-C like the rest of the electronics industry.
