What is the difference between iPhone 15's USB-C port and Mac/iPad?

In response to EU regulations, Apple finally transitioned the iPhone 15 series to the USB-C interface this year. The speed of the USB-C interface will bring users a more efficient data transmission and charging experience.

#Unfortunately, although the iPhone 15 series will transition to the USB-C interface, the transfer speeds will vary between different models.

Not only that, the USB-C interface of this iPhone 15 series is also very different in speed from the USB-C interface of previous Mac and iPad products.

The following are the USB-C interfaces of this iPhone 15 series and previous Mac and iPad Speed ​​differences between products’ USB-C connectors:

Existing Mac models: Thunderbolt (up to 40Gbps)

iPad Pro (2021 and 2022): Thunderbolt (up to 40Gbps)

iPad Pro (2018 and 2020): USB 3.1 Gen 2 (up to 10Gbps)

iPad Air (2022): USB 3.1 Gen 2 (up to 10Gbps) )

iPad Air (2020): USB 3.1 Gen 1 (up to 5Gbps)

iPad mini (2021): USB 3.1 Gen 1 (up to 5Gbps)

iPad (2022 ): USB 2.0 (up to 480Mbps)

Rumored iPhone 15 series:

iPhone 15 Pro Max: USB 3.2 or Thunderbolt (up to 20 or 40Gbps )

iPhone 15 Pro: USB 3.2 or Thunderbolt (up to 20 or 40Gbps)

iPhone 15 Plus: USB 2.0 (up to 480Mbps)

iPhone 15: USB 2.0 ( Up to 480Mbps)

What does this mean? In addition to charging, mobile phone interfaces also bear the function of data transmission. According to different data transmission speeds, they can be divided into USB2.0, USB3.0, USB3.2... The larger the number, the faster the transmission speed, and the higher the manufacturing cost. .

Currently, the USB-C interfaces of most Android phones and low-end tablets, as well as the iPhone’s Lightning interface, are USB2.0, which is a theoretical transmission speed of 480 Mbps. The USB-C of high-end iPad Pro and MacBook can reach 40Gbps transmission speed, which means that a 10G movie can be transferred in 2.5 seconds. This time the iPhone 15 Pro Max is equipped with USB 3.2 or Thunderbolt (up to 20 or 40Gbps), which is quite different from the standard version.
