Due to the sanctions imposed by the EU, the replacement of the USB-C interface of the iPhone 15 series has become a certainty. This has also been confirmed in the news of the supply chain. The lightning interface that has not changed for thousands of years has finally become history.

Since the birth of the iPhone, the form of the data cable has only been changed once: from the original 30pin interface to the lightning interface.

The 30pin interface is used on iPhone, iPhone 3G, iPhone 3GS, iPhone 4, and iPhone 4S. It can realize functions such as charging, data synchronization, audio output, playback control, video output, photo import, and USB input. It was already quite advanced at that time interface.

However, the shortcomings of the 30pin interface are gradually exposed: it is difficult to distinguish the front and back, and it is easy to damage the device; the volume is too large, taking up valuable internal space of the device.

So Apple introduced a new generation of interfaces: Lightning. There are 8 electric shocks on both sides of the lightning interface, which can be inserted regardless of the front and back, and the volume is reduced by 80%. More importantly, Apple introduced a chip on the Lightning interface. Since then, only by joining Apple's MFI certification, third-party manufacturers are eligible to produce this "authentic" peripheral.

Another ten years have passed, and the shortcomings of the lightning interface have also appeared: the transmission speed is only at the level of USB2.0; the upper limit of the charging power is only 30W, and the phone will heat up if it is higher.

Therefore, the replacement of USB-C is not only a compromise under the pressure of the EU, but also the lightning interface is really not powerful. The Thunderbolt 3 interface in the form of USB-C can achieve a transmission bandwidth of 40Gbps and a two-way 100W fast charging level. If this is used on the iPhone 15, it will be a turnaround.

However, according to Cook's knife method, the iPhone 15 series is reluctant to give such a good configuration.

The iPhone 15/iPhone 15 Plus does not change the medicine, it just gives you a USB-C appearance, and the internal speed is still USB2.0; the iPhone 15 Pro/Pro Max is slightly upgraded, and it barely gives Thunderbolt 3 for convenience The creator transmits 4K video, but the charging power is limited to less than 40W, and the rest will be paid next year

As for the charging head, there is still not in the box. Anyway, the user bought a 20W charging head with C port last year, and there is no need to change it this year.

So for ordinary users, the transmission speed has not changed, the charging speed has not changed, and even the charging head has not changed. The C port seems to have been changed, but it seems not to be changed... The biggest victim should be the accessories that make the lightning interface business.
