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.
This is not correct for devices being sold to the EU at least. Part of the amendment to the Radio Equipment Regulation outlines the exact standards for power delivery that must be used, and that interfaces which are capable of being charged @ > 15W must “ensure that any additional charging protocol allows for the full functionality of the USB Power Delivery…”.
For data transfer, I don’t see the point and future improvements to USB will come from industry in future.
The only way around this is with a wireless charging protocol, but manufacturers are moving away from that it appears.
