On April 18, iDropNews reported that the Lightning interface will continue to be used on the iPhone 14 series models, and there are no plans to use USB-C until MagSafe can replace wired transmission. However, it is reported that Apple is developing a USB 3.0 speed version of the Lightning interface for this year's new flagship to increase the file transfer rate of the new machine.
According to iDropNews, there is also a reason for not using the Type-C interface is "revenue", from the Lightning interface to MagSafe, Apple can always charge third-party accessory manufacturers for MFi certification fees for data cables, chargers and other ports.
So far, the transmission speed of Apple's Lightning data cable is only equivalent to USB 2.0 (up to 480Mbps), but the iPhone 13 Pro has entered the ProRes era, shooting a 1-minute ProRes 4K video capacity of about 6GB, then using the current Lightning data cable to transfer files to the computer will be a little too slow, but if the transfer speed reaches USB 3.0 (up to 5Gbps), the transfer burden will be much smaller.
Since the iPhone 5 in 2012, Apple began to use the data cable of the Lightning interface, which has been 10 years old, and since the launch of the Lightning interface, the data line has hardly changed except for the surface material.
