According to Kuo, not all iPhone 15s will be able to transfer files at high speeds via USB-C.

All roads lead to iPhone 15 It will implement a USB-C port, although Apple does not like the idea very much. However, this new feature will come with a significant data rate limit for “non-professional” models.

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

While these are rumors and should be treated with a pinch of salt, it wouldn’t be unusual if they turned out to be true. Especially because of the most notable differences seen this year between the iPhone 14, iPhone 14 Plus, and Pro models, both in processor, screen, and other specs.

According to Kuo, iPhone 15 Pro and Pro Max will support at least USB 3.2 or Thunderbolt 3 specifications. If that happens, you’ll notice a jump in quality when you move large files from your mobile phone to your computer—like a video shot in ProRes—you’ll notice.

How fast can an iPhone 15 with USB-C transfer files?

Of course, the claim that the iPhone 15 Pro will use “USB 3.2” can be misleading; or at least not being able to paint a complete picture of the problem. Especially when you consider that specification designations have changed a lot in recent years. Since its launch in 2017 there are four USB 3.2 options:

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

The latter is the fastest as it allows data transfer up to 20 Gbps; something like 2.5 GB per second, and only works with USB-C. Without a doubt, this would be the preferred option for any iPhone 15 user if it did come with USB 3.2 support.

Although the thing could be even better if they implemented a port Thunderer 3. This is what it supports baud rate up to 40 Gbpsabout 5 GB per second.

If you are wondering what will happen to the standard iPhone 15 and Plus, Kuo assures that will be tied to USB 2.0 speed. That is, the same ones that are currently being tested with the Lightning port and which allow you to transfer files at a maximum speed of 480 Mbps (60 MB per second).

It’s still a long way from seeing the iPhone 15 in action, but there are already a few rumors about its supposed specs. For example, it has already been said that Apple will remove the physical volume and power buttons, and that neither model will have a cutout. The latter will open the door for the implementation of Dynamic Island iPhone 14 Pro in all future generation mobile phones designed by Cupertino.

Finally, the iPhone 15 is expected to continue to use 5G modems developed by Qualcomm. While Apple is working on its own cellular chip, some models have reported overheating issues. Therefore, its implementation have to wait at least another year.
