USB-C on iPhone 15 Will Limit Data Speeds on Cables Without MFi Certification, Compatible Accessories Underway

wccftech.com:

Apple will launch the new iPhone 15 and iPhone 15 Pro models later this year with a wide range of new features and forward-facing changes. The devices are finally adopting USB-C after years of feedback from users. While it is great news, there is a catch that you should know of. The USB-C port on iPhone 15 will limit data transfer speeds with cables that are not MFi certified. What this means is that the accessories need to be compatible with Apple's standard in order to fully take full advantage of the port.

You might have come across a message on your iPhone that says "This accessory is not supported." Well, the Made for iPhone or MFi accessories come with a dedicated chip that confirms if the accessory meets the company standards. You will be presented with a prompt telling you that the accessory is not supported if it is made by third-party sellers. Apple has adopted the approach for more than a decade now and it will be brought forward with USB-C port on the iPhone 15.

Despite Apple's good will to bring USB-C to its iPhone lineup later this year, not all cables will be compatible to transfrer wired data at maximum speed. You will have to buy an MFi cable or any other accessory with the standard to make use of the USB-C port's full potential. It was coined by ShrimpApplePro that this year's iPhone 15 models will come with USB-C with MFi. Furthermore, Apple's main supplier Foxconn has already begun the production of MFi compatible accessories.

Much like how Apple stops signing older iOS builds so users can enjoy the latest features and security updates, the chip that authenticates accessories encourages users to purchase original add-ons. Furthermore, it is also easier to distinguish between genuine and fake accessories.
