It has already been widely reported that Apple is transitioning from iPhones with Lightning connectors to USB-C iPhones, but it has now also been stated that the two lower-end iPhone 15 models won’t see much of a data transfer speed improvement over those of previous iPhone generations, despite the connector change. According to LeaksApplePro (writing for HowToiSolve), only the two higher-end iPhone 15 devices will be treated to superfast rates that are “similar to USB 3.2 technology”. Something like this has been predicted before by Ming-Chi Kuo; however, this latest report claims that this has basically been confirmed in operating software code.
So, while the wait for a USB-C iPhone seems to be nearing its end, it appears that the devices will not be created equally. The likely named Apple iPhone 15 and Apple iPhone 15 Plus will shed the Lightning ports but will supposedly find their USB-C ports restricted to a similar data transfer rate as found in the iPhone 14 Pro, which according to a report from 2022 is the lethargic USB 2.0 speed of 480 mbps (60 MB/s). In other words, Cupertino may have found yet another way to differentiate the entry-level iPhone 15 models from the Pro devices.
The good news though, at least for those who snap up an iPhone 15 Pro or iPhone 15 Pro Max (aka iPhone 15 Ultra), is that the higher-end phones could end up transferring data at rates of up to 5 Gbps (625 MB/s). That is the speed limit for USB 3.2 technology, which according to the apparent new iOS 17 code leak, is what is being reserved for the 2023 USB-C iPhone Pro models. If true, it would certainly be seen as a considerable selling point to iPhone users who view this particular area as a frustrating con for the popular smartphone series.
