One of the biggest mistakes of the USB-IF was allowing Type-C to operate at USB 2.0 speeds 🙄 There is no reason for that to exist as USB 3.0 (5 Gbps) should be the bare minimum.
Industry analyst Ming-Chi Kuo says the USB-C ports on the iPhone 15 lineup could be rated differently. The iPhone 15 Pro and iPhone 15 Ultra will get one that operates at USB 3.2/Thunderbolt 3.0 speeds, whereas the iPhone 15 and iPhone 15 Plus will be restricted to USB 2.0.
