Recent leaks suggest that Apple's imminent iPhone 15 series will accept only those USB-C accessories that have received Apple's Made for iPhone (MFi) certification.

This means users employing USB-C cables without the MFi certification will face limitations on charging speeds and data transmission capabilities with the new iPhone variants.

Since 2012, third-party Lightning ports and cables with MFi certification have included a tiny integrated circuit that certifies the authenticity of connection components. Non-MFi certified third-party cables lacking this chip often result in a 'This accessory is not supported' message on connected Apple devices.

The upcoming models set to debut later this year are expected to switch to USB-C ports from Lightning, and recent reports indicate that the iPhone's USB-C port will require a similar authentication chip.

Apple's strategy with this move is to encourage the purchase of official accessories, thereby mitigating risks like fire and explosions. Additionally, Apple earns a commission from the sale of MFi certified accessories.

According to Apple analyst Ming-Chi Kuo, the USB-C ports on the iPhone 15 and iPhone 15 Plus will remain limited to Lightning/USB 2.0 speeds, while enhanced data transfer rates will be exclusive to the and iPhone 15 Pro Max models. Apple continues to segment its basic and Pro user bases, something to watch out for!
