A switch from Lightning to USB-C
Apple had been testing versions of the iPhone 11 with a USB-C port instead of the Lightning connection the company has been using since 2012, according to Bloomberg. All of Apple's new iPhones, however, still use Apple's proprietary charging port.
But the new iPhones do come with a Lightning to USB-C cable, unlike older models which used a previous USB standard. That means you'll be able to connect the new iPhones to modern MacBook laptops for charging or transferring data without having to order a Lightning to USB-C cable.
Apple Pencil support
Analysts at Citi Research also suggested that Apple's new iPhones would come with support for the Apple Pencil, although that turned out to be untrue.
Following Apple's July earnings report, Citi Research shared a note outlining what it expected to see from the company's 2019 iPhone lineup. On the list of expected features was "support for iPhone pencil/stylus."
It's not the first time we've heard rumblings of Apple potentially extending Pencil support to its iPhones. Kuo mentioned it as a possibility in a research note from 2018, especially if Apple continues expanding the iPhone's screen size, as MacRumors reported.
The Apple Pencil still only works with various iPad models, as Apple outlines on its website.
