  • Post comments:0 Comments


The unveiling of Apple’s latest iPhone lineup, including the iPhone 15 and the iPhone 15 Pro, has tech enthusiasts buzzing. Among the notable changes is the adoption of the USB Type-C charging port. However, a closer look reveals that not all USB-C ports are created equal. In this blog post, we delve into the details to explain why the USB-C port on the iPhone 15 Pro stands out.

The USB-C Evolution

The USB-C port is becoming increasingly ubiquitous in modern devices, promising faster data transfer and more versatile connectivity. Both the iPhone 15 and the iPhone 15 Pro feature this advanced port, but their performance differs significantly.

Behind the Scenes: A Tale of Two Chips

The key to understanding the USB-C discrepancy lies in the internal hardware. The iPhone 15 Pro is equipped with Apple’s cutting-edge A17 Pro APU, boasting a brand-new on-die USB controller block. This controller optimizes USB-C functionality, allowing for a blazing 4.8 Gbit/s (600MBps) data transfer rate and faster charging.

In contrast, the standard iPhone 15 relies on the previous-generation A16 Bionic chip. Unfortunately, this older chip lacks the enhanced USB controller found in the A17 Pro APU, resulting in a limited USB-C capacity of 480 Mbit/s (60MBps).

The USB Speed Dilemma

The implications of this hardware difference are significant. USB 3.0, as utilized in the iPhone 15 Pro, offers a data transfer rate of 4.8 Gbit/s (600MBps), ensuring quicker data transfers and faster charging. On the other hand, the vanilla iPhone 15 is limited to USB 2.0 speeds, which offer a mere 480 Mbit/s (60MBps).

The Mystery of USB Implementation

While the exact technical details of how Apple has implemented USB on the iPhone 15 are not entirely clear, the limitations of USB 2.0 speeds are apparent. This suggests that there may be a conversion process at play, bridging the gap between the new USB-C connector and the legacy Lightning controller, ultimately constraining the iPhone 15 to USB 2.0 speeds.
