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.
They kinda already do different physical models for different regions. NA has no SIM card slot, China requires 2, rest of the world gets 1.
With that being said, charging ports might be a different beast.
That’s easy though because they just swap out a daughter board but with apples design the charge port is soldered directly onto the main board so they have to change that and it’s probably easy to not do that.
Very few phones actually have daughter boards for the charging port. Pretty much the only ones that are phones aimed at repairability.
