Although Apple had previously confirmed that these devices support USB 3, this latest disclosure provides clarity on the exact specification. It’s important to mention that the USB-C cable that comes with iPhone 15 Pro models only supports USB 2 speeds, so if you desire faster data transfer, you’ll need to invest in a higher-spec cable.

This can be achieved with a compatible USB-C to DisplayPort cable or an appropriate adapter.
