Ports have been a fixture on mobile phones since their inception — dating all the way from the iPhone 12 back to “dumb phones” from decades before. But even when it comes to ports, Apple has done things its own way. In 2012, the company made its own accessories obsolete when it switched from a 30-pin connector to a proprietary Lightning port, and has since resisted from switching to a USB-C connector on iPhones even though it eventually became accepted as a universal standard. (There are Lightning-to-USB-C cables, however.)
