Apple currently offers a 35W Dual USB-C charger brick for $59 in the Apple Store
To turn a commodity USB-C charging cable into a proprietary one, Apple might decide to make it possible for third-party USB-C cables to work with the iPhone 15 line only if they have been certified under Apple’s MFi (Made For iPhone) program. Leaker ShrimpApplePro says all of the third-party USB-C accessories made for the iPhone 15 lineup will have to be MFi-certified to work with the 2023 iPhone models.
As for data transfer speeds, the iPhone 15 and iPhone 15 Plus could see this rate remain at the same 480Mbps delivered by the Lightning port. the iPhone 15 Pro and iPhone 15 Pro Max could see faster data transfer speeds of 20Gbps to 40Gbps. At the latter speed, the iPhone 15 Pro handsets would support Thunderbolt 4.0. There are so many possibilities, let’s hope that Apple Store reps have their spiel down pat by the expected release date of September 22nd.
