According to Ming-Chi Kuo, an Apple analyst, the transition to USB-C would enable quicker wired transfer speeds on the iPhone 15 Pro models, which are expected to be released in 2019.
Although all iPhone 15 models will have USB-C connectors instead of Lightning ports, only the iPhone 15 Pro versions will have quicker transfer speeds. The normal iPhone 15 models will retain USB 2.0 speeds, which are the same as Lightning rates.
Kuo predicts that with compatibility for “at least” USB 3.2 or Thunderbolt 3, transfer rates on the iPhone 15 Pro versions will “increase considerably.” Thanks to the improvement, the new iPhone 15 Pro models will be able to transport video files and other file types at quicker speeds, and Kuo forecasts a considerably improved user experience.
While USB 3.2 can transport data at speeds of up to 20Gb/s, USB 2.0 can only send data at 480Mb/s. If Kuo is correct, wired data transfer speeds will differ significantly between the Pro and non-Pro iPhone 15 variants because Thunderbolt 3 offers data transfer speeds of up to Apple 40Gb/s.
The first USB-C iPhones are expected next year, as Apple transitions its entire product line to USB-C. Apple is making the change in order to comply with European laws that require non-proprietary, widely available charging methods for electronic devices.
