Apple revealed that its newest product line, the iPhone 15, will drop the company’s proprietary Lightning port in favor of European-mandated USB-C ports. The company’s newest iPhones feature a charging plug that is slightly bigger and rounder than its predecessor but capable of delivering a faster charge. The rule was aimed at reducing electronic waste and saving customers money by making one port compatible across an array of devices. Though Apple resisted the change, warning that government mandates could stifle innovation, it will make it possible to use the same USB-C cord that powers a Mac to charge an iPhone. In addition to the iPhone, the company unveiled its wireless earbuds, the AirPods Pro, with a USB-C charging case.The change speaks to how regulators are altering Apple’s business. Apple has positioned itself as the primary gatekeeper for more than one billion iPhone users worldwide by building proprietary hardware and services. To reach those customers, app developers have given the company as much as a 30 percent cut of their sales, and accessory companies have paid fees to make cords with Lightning ports.
