As expected, the iPhone 15s abandon the proprietary Lightning format to switch to USB-C, but to take advantage of the full capabilities of the new standard, in particular for the iPhone 15 Pro/Pro Max models compatible with USB-C 3.0 (on the contrary iPhone 15/15 Plus whose port is limited to USB-C 2.0), you may have to pay a little more.
Apple Thunderbolt USB 4 Gen 2 cable approaching?
Indeed, according to “leaker” KosutamiSan on Twitter/X, Apple should put on sale an 80 cm Thunderbolt USB 4 Gen 2 cable with a power of 150 watts. It would make it possible to achieve faster loading and transfer speeds than with the basic cable supplied limited to USB-C 2.0 (i.e. 480 Mbits/s), as rumors already predicted at the end of the last year.
Note that, cable or not USB 4 cable from Apple, there are numerous USB 3.2 Gen 2 specimens on the market, rather affordable, for those who would like to benefit from the capabilities of the USB-C ports of their future iPhone 15 Pro/Pro Max.
