Apple is testing iPhones that use the industry-standard USB-C port, according to a report in Bloomberg citing people with knowledge of the situation.
Since 2012, Apple's smartphones have used the company's proprietary Lightning connector. But more recently, the slightly larger USB-C port has come to dominate consumer electronics, including most of Apple's other products. Consumers, reviewers, and even government regulators have called for Apple to drop Lightning in favor of USB-C in recent years.
On the other, Apple could switch to USB-C, making the iPhone play more nicely with other gadgets, including the Mac. But that move could trigger consumer confusion and chaos among accessory-makers. It would also loosen Apple's control over the user experience.
The third option would be to go all-wireless, but wireless connections usually don't transmit power or data as quickly or efficiently.
