Apple is expected to replace the good old Lightning port with USB-C this year. New alleged images of the iPhone's USB-C port attached to the PCB components of various models have surfaced online.
While Apple has publicly accepted that it will switch to USB-C, the actual implementation might not be straightforward. A new rumor says that Apple might slow down unofficial USB accessories.
With the potential switch to USB-C ports from Lightning on future iPhones, rumours are that features will be limited unless you use a cable that has been made by Apple or is Apple Certified.
