After rumors that Apple is preparing to change the charging port in the iPhone 15 to USB-C, now an engineer has modified the current iPhone to have two charging ports, both Lightning and USB-C.
One of the benefits of this modification is that users can charge their phones and use wired headphones at the same time after Apple removed the headphone jack from its own phones starting with the iPhone 7.
A video clip of the manufacturing process and testing of the dual-port iPhone can be viewed from the link below.
