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.
Just carrying it in my pocket all day, nothing unusual. I might get a bit more lint forming or dust falling into my pocket than some people since I have a fairly active job but that applies to many others too. It’s not just a USB-C thing either as I found micro USB to similarly build up stuff inside the port. Headphone jacks I never had a problem with when I had a phone or mp3 player with one, I guess they’re less prone to this issue.
Edit: Never had issues with lint build up in the old Nokia charger port either, micro USB was the first port I really noticed it happening with.
