If the iPhone model supports USB 3.2 Gen 2, then using a USB-C data cable that supports USB 3 is typically the fastest and most stable method for migrating large amounts of data between two iPhones.
Apple’s official documentation indicates that the following iPhone models support USB 3.2 Gen 2 data transfer at up to 10Gbps:
iPhone 18 Pro series
iPhone 17 Pro series
iPhone 16 Pro series
iPhone 15 Pro series
Please note that 10Gbps is the theoretical maximum transfer rate of the USB interface and does not mean that the entire iPhone migration process can achieve this speed. Actual migration speeds will also be affected by factors such as storage read/write performance, file count, system processing, and migration protocols.
Additionally, to achieve USB 3 high-speed transfer, you need to use a data cable that supports USB 3; the standard USB-C charging cable included with the iPhone does not support 10Gbps data transfer.
