On December 29, MacRumors reported that Apple would be looking at the Apple Watch Ultra,The top version of the iPhone 15 series will be renamed the iPhone 15 Ultra instead of the Pro Max.
It also noted thatThe iPhone 15 Ultra will be manufactured by two factories, Lishun Precision and Foxconn, as Apple aims to diversify its iPhone production partners.
One of the most important changes to the iPhone 15 Ultra is the USB-C charging port. The European Union played a big part in Apple's decision. Apple's decision to change the charging port for the iPhone was prompted by a recent European Union law that requires all electronic devices entering Europe to use USB-C.
Compared with Lightning port, USB-C has obvious advantages. For example, it supports up to 100W of fast charging power, and is compatible with many protocols. The maximum transmission rate can reach 40GB/s.
On the other hand, Apple's Lightning technology is old, with high delay, shameful charging speed and poor compatibility.Since only Apple devices have this interface, you'll need to buy a docking station for more functionality.
In addition, according to the industry chain, the iPhone 15 base will use the same A16 chip as the iPhone 14 Pro series,Only the iPhone 15 Pro and iPhone 15 Ultra have exclusive A17 chips based on TSMC's 3nm process.
In other specs, the iPhone 15 Pro and the iPhone 15 Ultra will include an upgrade from 6GB of RAM to 8GB, and to appease base iPhone 15 owners, Apple will include a 48-megapixel lens and a pill screen.
