It is rumored that one of the highlights of Apple’s iPhone 15 is to abandon Lightning and switch to USB-C, which can not only be used for multiple purposes, but more importantly, it supports faster transmission speeds. According to foreign media reports, Apple is expected to bring the Thunderbolt specification, so that large-capacity video transmission is no longer a pain point for the iPhone.
The “ChargerLAB” website broke the news, obtained spy photos of the USB-C parts of the new iPhone 15, and found a mysterious Retimer chip, which used to be installed on Thunderbolt or USB-4 devices to enhance the stability of data transmission. Installed in 3 different models, it is predicted that at least 3 iPhones will support Thunderbolt, possibly mainly high-end models such as iPhone 15 Pro and 15 Pro Max.
As for what benefits can Thunderbolt bring? It has been widely used in iPad Pro and Mac computers. “9to5mac” analyzed that compared to the iPhone’s old Lightning interface, which is based on USB 2.0 technology, the transmission speed is only 480 Mbps, while the general USB-C interface is about 5-10 Gbps, and if it supports Thunderbolt, it can reach 40Gbps. High speed transmission.
Through the high-speed transmission brought by Thunderbolt, it can improve the shortcomings of professionals using the iPhone to create. With Apple’s ProRes video specification, the video files have become very large. Uploading via the Internet will take time and occupy the capacity of the cloud. Lightning wired transmission is too slow, and Thunderbolt can improve the above shortcomings and make the rumored 2TB iPhone 15 models more valuable.
