The speculation states that non-professional phones would still receive the new connector but will only be able to transfer data at USB 2.0 speeds.
According to renowned analyst Ming-Chi Kuo, the iPhone 15 Pro models will experience a significant improvement in their wired transfer speeds with the move to USB-C. Unfortunately, he doesn't think that feature will be available for the ordinary iPhones in 2023. He anticipates that the 15 and 15 Plus will switch to USB-C connectors as too, although they will still only support the same USB 2.0 speeds as the Lighting-enabled 10th-generation iPad in 2022.
The forecast was made by Kuo in a string of tweets on Wednesday, and he claims the data comes from his "latest study." (The analyst is renowned for using supply chain sources to gather information.) The "15 Pro & 15 Pro Max will support at least USB 3.2 or Thunderbolt 3," he specifically stated.
If so, they would be able to transport data at rates of up to 40 Gbps, which would be beneficial for those who use the Pro phones to shoot a lot of ProRes video and raw images as fast WiFi and cloud uploads aren't really a good replacement.
As of late, it appears that Kuo has additional information on how Apple will use USB-C to differentiate its devices and how the 2023 crop of iPhones will feature it. In May, Kuo predicted that the change in connection "may boost iPhone's transfer and charging speed."
Since then, the EU has mandated that new phones must utilize USB-C if they include a charging connector (a rule Apple hinted it will reluctantly follow), though the requirement won't take effect until fall 2024.
It won't necessarily come as a surprise if Apple increases the transfer speeds for its upcoming pro models but not for the normal ones. While the mainline versions continued to use the internal technology from last year, the iPhone 14 Pro received a new chip this year. Better wired speeds feel like the kind of feature that pros would value, and Apple has been looking for ways to differentiate its higher-tier phones ever more. This is particularly relevant considering that the standard iPhones do not yet support advanced content creation tools like ProRes video or raw images.
With support for "at least" USB 3.2 or Thunderbolt 3, Kuo claims that transfer speeds on the iPhone 15 Pro versions will probably "increase considerably." The new iPhone 15 Pro versions will be able to transport video files and other file types at faster rates thanks to the change, and Kuo anticipates a noticeably better user experience.
The first USB-C iPhones are expected next year when Apple switches over to USB-C across its entire product line. Apple is making the adjustment to adhere to European laws that need non-proprietary, widespread charging methods for electronic gadgets.
