Not all iPhone 15 will be able to transfer files at high speed via USB-C

All roads point to the iPhone 15 It will implement the USB-C port, although the idea is not very fond of Apple. However, this new feature would be accompanied by a significant limitation in data transfer speed for "non-Pro" models.

This was stated by Ming-Chi Kuo, who in his most recent prediction indicated that while all versions of the iPhone 15 will receive USB-C, only Pro and Pro Max variants will support high-speed file transfer.

Although it is a rumor, and as such should be taken with a grain of salt, it would not be unusual if it turned out to be true. Especially due to the most marked differences that have been seen this year between the iPhone 14, the iPhone 14 Plus and the Pro line models. Both in processor, screen and other features.

According to Kuo, the iPhone 15 Pro and Pro Max will support "at least" USB 3.2 or Thunderbolt 3 specifications. If it materializes, the quality leap when it comes to moving large files from the mobile to a computer —videos filmed in ProRes, for example— would be noticeable.

At what speeds could iPhone 15s with USB-C transfer files?

Of course, saying that the iPhone 15 Pro will use "USB 3.2" can be somewhat misleading; or, at the very least, fail to paint a complete picture of the issue. Especially when you consider that spec designations have changed quite a bit in recent years. Since its introduction in 2017, there are four variations of USB 3.2:

  • Gen 1x1 (formerly known as USB 3.0 and USB 3.1 Gen 1);
  • Gene 1x2;
  • Gen 2x1 (formerly USB 3.1 Gen 2);
  • Gen 2x2.

The last one is the fastest, since it allows a data transfer of up to 20 Gbit/s; something like 2.5 GB per second, and it works only with USB-C. Without a doubt, it would be the preferred option for any iPhone 15 user, if it really came with support for USB 3.2.

Although the thing could be even better if it implemented a port Thunderbolt 3. It is that this supports data transfer speeds of up to 40 Gbit/sabout 5 GB per second.

If you wonder what will happen to the standard iPhone 15 and Plus, Kuo assures that will be tied to USB 2.0 speeds. That is, the same ones that are currently experienced with the Lightning port and that allow you to transfer files at a maximum of 480 Mbit/s (60 MB per second).

There is still a long way to go to see the iPhone 15 in action, but there are already several rumors about its alleged specifications. For example, it has already been said that Apple would eliminate the physical volume and power buttons, and that no model would come with a notch. The latter would open the door to the implementation of the Dynamic Island of the iPhone 14 Pro in all the models of the future generation of mobiles developed by those of Cupertino.

Lastly, the iPhone 15s are expected to continue to use 5G modems developed by Qualcomm. Although Apple is working on its own cellular connectivity chip, overheating issues have been reported in some models. Therefore, its implementation would be made to wait for at least one more year.
