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.
iirc the new EU law that apple is responding to doesn’t say that a mobile device can’t have a proprietary port, rather it says that a mobile device must have a USB-C port for charging. But i might be wrong about that.
