Apple is to change gear to USB-C for its new phones, though it remains to be seen when the change happens. Well-known analyst Ming Chi Kuo is confident that the port change will take place in the second half of 2023, which should coincide with the launch of the iPhone 15 series.
Kuo believes Apple will bring USB-C to all of its new iPhone 15 models, though only the 15 Pro and 15 Pro Max will get USB 3.2 standard or at least Thunderbolt 3, which should manage up to 40Gbps for data transfers . The iPhone 15 and 15 Max are stuck at USB 2.0 speeds (up to 480 Mbps), just like current backlit iPhones.
Apple has a long history of differentiating features between its Pro and vanilla model iPhones, so a fast USB-C connector sounds like a logical step for Cupertino. Kuo also speculates that Apple could add solid state volume buttons to the 15 Pro series. The 15 Pro Max may also get one periscope lens with a magnification of up to 6x.
