Kuo: iPhone 15 Pro and iPhone 15 Pro Max USB-C Port Could Feature Thunderbolt 3 Support

Apple’s next-generation iPhone 15 Pro and iPhone 15 Pro Max USB-C port will offer support for at least USB 3.2 or Thunderbolt 3, according to analyst Ming-Chi Kuo. This feature would deliver an impressive speed advantage over existing Lightning connector-based iPhones.

Thunderbolt 3 offers theoretically bandwidth of up to 40 Gbps, while the current iPhone’s Lightning connector offers USB 2.0 speeds of up to 480 Mbps.

This means that even with real-world limitations the iPhone 15 Pro with a Thunderbolt-enabled USB-C port would face, it would still significantly outperform today’s transfer speeds when using a Thunderbolt cable. This will make it much faster when transferring large files.

Even if the iPhone 15 Pro models are limited to only USB 3.2 speeds, it would deliver theoretical transfer speeds of between 5 Gbps and 20 Gbps, which is still significantly faster than Lightning.

Kuo has previously said that while all iPhone 15 models will replace their Lightning ports with USB-C, standard ‌iPhone 15‌ models will continue to feature USB 2.0 speeds, the same as Lightning.
