August 24th, according to HT Tech,Apple has begun work on the iPhone 15, which will debut in the second half of 2024.

For the iPhone 15 series,The biggest change is the removal of the Lightning port in favour of USB-C.

Since the European Union has made USB-C mandatory for all phones in 2024, the 2024 iPhone 15 series will come standard with USB-C.

Compared to Lightning,Usb-c is compatible with many existing non-Apple devices and has faster data transfer and charging speeds.

In terms of data transmission speed, USB-C interface supports the latest and fastest USB 4 standard, and the transmission speed can reach 40Gbps. In contrast, Lightning is the USB 2.0 standard, usually around 480Mbps.

On top of that, USB-C offers a higher charging rate than Lightning, allowing for faster charging at the same voltage.

It's worth noting that the iPhone 15 will continue Apple's differentiation strategy, just like the iPhone 14 series.

To be specific,The standard iPhone 15 uses the same chip as the iPhone 14 Pro, the A16, while the iPhone 15 Pro series uses the newer A17 chip.
