iPhone 15 USB-C cables without MFi badge may have data transfer and charging speed limits

Apple's iPhone 15 series will officially only support USB-C accessories that have been certified by Apple's own Made for iPhone (MFi) program, potentially limiting the functionality of accessories not approved by Apple, an established leaker has now claimed.

So you're getting USB-C, but not really. Leave it to Apple to milk even something as mundane as this.
