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
