We’ve known that the iPhone is switching to USB-C for a while now, but there was always a possibility that Apple would stick with Lightning for one more year. Based on the latest leaked images, however, Apple is all-in on USB-C for the iPhone 15 and iPhone 15 Pro models, with USB-C parts for the iPhone 15, iPhone 15 Plus, and iPhone 15 Pro Max all shown in a leaked image by X user fix Apple.
With the switch to USB-C, nearly all of Apple’s devices will have adopted the new standard, with only AirPods, Mac accessories, and the iPhone SE remaining aside from older iPhones and the 9th-gen iPad.
iPad Pro (2020 model onwards if I recall correctly) already uses USB type C already so it shouldn’t be any different.
I could charge my android phone with it for example and in couple occasions I have done so.
Honestly, the fact that apple used usb-c on it’s “pro” iPads but not the regular iPad is all the proof we need that even apple thinks usb-c is better
It’s likely more to do with the iPad Pro architecture being essentially the same as a MacBooks. Makes it easier to produce multiple devices based on the same components. But they kept Lightning on the cheaper devices because the people using them are less likely to care how they (very infrequently) plug stuff in.
