Although Apple has long since changed the iPad interface to USB-C, the iPhone and AirPods have always used the Lightning interface, and Apple can use this to charge patent licensing fees. The European Parliament's Internal Market and Consumer Protection Committee announced an agreement to unify charger standards 40 months after the implementation of the new regulations (ie 2024). Regulated products include: smartphones, digital cameras, tablet computers, e-book readers Devices, headphones, portable game consoles, portable speakers, etc. must all be charged using USB-C. The motion also stipulates that chargers and electronic products must be sold separately, and chargers must not be included in products. Fast charging technology also needs to further strengthen the compatibility of chargers and devices. One-fifth of Apple's iPhone sales in 2021 will come from Europe. So Apple had to come up with a solution, with news that Apple is preparing to switch the iPhone to charging via USB-C. But USB-C iPhones won't appear until 2023 at the earliest.
