The proprietary Lightning port is used to fuel a number of the company’s iPhones, iPads, iPods, and a lot of Apple’s partners have formed long-term business relationships to churn out a multitude of accessories designed for these products. This ‘extended accessories ecosystem’ would make it extremely difficult for customers to shift to a newer standard immediately. That’s why it comes as no surprise when Apple was defending its charging port, though European lawmakers see things differently and propose that all smartphones should be topped up using a single, standardized port.

Ensuring that a single charger needs to be compatible with all portable devices is a daunting challenge, but some members of the European Parliament want ‘binding measures’ that it’s done. According to the information that MacRumors dug up, the European Commission simply want to encourage tech companies to develop a standardized solution. The available solutions are microUSB, Type-C USB and the Lightning connector. The latter can’t be used as it’s a proprietary connector with which Apple also earns royalty, so that’s out of the equation.
