1. Apple's upcoming iPhone 15 series is expected to feature a significant design change, with the introduction of a USB-C port instead of the traditional Lightning connector. This move is driven by new EU regulations that mandate USB-C as the standard charging port for all smartphones, tablets, and other small electronic devices sold in the European Union by the end of 2024.

2. The switch to USB-C is a significant departure from Apple's longstanding use of the proprietary Lightning connector, which has been a defining feature of the iPhone since its introduction in 2012. This change is likely to have broader implications, as it could potentially impact Apple's ecosystem of accessories and the company's ability to control the charging experience for its devices.

3. The article also notes that the iPhone 15 series is expected to bring other notable upgrades, such as improved camera systems, faster processors, and potentially even a periscope-style telephoto lens on the Pro models. These advancements are expected to keep the iPhone competitive in the rapidly evolving smartphone market.
