They support Power Delivery 2 and higher just fine. I believe the new phones will use 3.0 PPS as well to more aggressively tune for charging speed vs heat.
USB Power Delivery 1 was a disaster, launched years after Apple had moved beyond 7.5W charging. Android phones typically also ignored it, using Qualcomm's proprietary charging tech.
If you want fast charging, use the bundled USB-C cable to charge your iPhone rather than the USB-A ones from years ago.
To flip it around, what advantage do you think one gets with official Apple iPhone chargers? Do you know of any evidence that Apple promotes their chargers working better than others? And if none exists, why would they sabotage customers who were never educated that hypothetically only Apple chargers charge fast?
Actually having just tested, I have a bunch of "aftermarket" lightning cables, and a few of them some of my iPads (I think the more recent ones) and most of my iPhones refuse to charge. Like at all.
So not fast charging, charging at all. They work on some of the iPads, so they do work.
Why do the phones refuse to charge then? Not fast charging, which I can sort of understand, charging at all.
