Apple is reportedly planning to offer a new USB-C data transfer accessory cable for its upcoming iPhone 15 Pro models, according to a tweet from well-known leaker Kosutami. The cable is said to be 0.8 meters long, shorter than Apple’s existing Thunderbolt 4 Pro cable, and will support Thunderbolt or USB4 speeds of up to 40Gbps. It will be sold separately from the iPhone.
This news comes amidst speculation about the port standard that Apple will use for its premium iPhone 15 Pro and iPhone 15 Pro Max devices. As the company transitions to USB-C across all iPhone 15 models, Apple analyst Ming-Chi Kuo has previously stated that the Pro models will support “at least” USB 3.2 or Thunderbolt 3. However, the leaked USB4 cable is based on the Thunderbolt 4 protocol, offering speeds of 40Gbps, twice as fast as the previous USB 3.2 Gen 2 standard.
It is important to note that while the leaked cable claims to support charging up to 150W, this does not necessarily mean that the iPhone 15 Pro models will be capable of charging at this speed. Previous reports have suggested that the iPhone 15 models would support faster charging speeds due to the transition to USB-C.
There have also been rumors circulating about the cables that will be included in the iPhone 15 boxes. Some reports suggest that the cables supplied with the standard models may be limited to USB 2.0 data transfer speeds, while the Pro models are expected to come with cables capable of USB 3.2 or Thunderbolt 3 speeds.
Images from ChargerLab have further fueled speculation, showing a Thunderbolt/USB 4 retimer chip in some iPhone 15 models. This confirms the earlier rumor of higher-speed data transfer for the Pro models.
Additionally, each iPhone 15 will come with a braided USB-C charging cable that is thicker and 50% longer than the Lightning cable included with current iPhone models. These cables are rumored to be color-matched to the possible new iPhone colors.
Apple is expected to officially announce its new iPhone 15 lineup on September 12.
