(Pocket-lint) - After a decade of including a Lightning port on all iPhone devices, Apple is reportedly considering dropping it for a USB-C port.

Bloomberg has claimed the Cupertino-based company is now testing iPhone units that swap the Lightning port for USB-C. But don't expect to see the switch in this year’s iPhone lineup. The move to USB-C  likely won't happen until 2023 "at the earliest", Bloomberg's Mark Gurman said.

Keep in mind Apple analyst Ming-Chi Kuo - who is well-known for accurately predicting Apple's product roadmap - also recently suggested Apple would ditch the Lightning port in favour of USB-C in the second half of 2023.

The 2023 iPhone won't be the first Apple device to come with USB-C. Apple already offers it on the iPad Pro, iPad Air, and iPad Mini because USB-C is capable of faster transfer speeds.

So, why did Apple wait so long to consider bringing USB-C to the iPhone, especially because it's been years since the technology became popular? Well, Gurman pointed to a European Union proposal that would require many devices, including phones, to have USB-C. Gurman specifically said this legislation was "a key reason" for Apple's switch to USB-C.

Oh, and remember that portless iPhone Apple supposedly began developing? Bloomberg's report made it seem like that's not going to be a thing anytime soon.
