Regarding the new generation of iPhone 15 series that will arrive in the second half of this year, there have been many revelations.
Among these revelations, one of the most anticipated upgrades is that the iPhone will cancel the Lightning interface and use the USB-C interface.
It is reported that since Apple released the Lightning interface in September 2012, the iPhone series has been using this design. Now 10 years have passed, and the outside world hopes that Apple will replace the interface for the iPhone has gradually increased.
Based on this, it would not be too surprising if Apple really changed the interface design for the iPhone series.
At the same time, with the advancement of time, the details of the USB-C interface that are expected to be used in the iPhone 15 series have also been revealed.
The latest news mentioned that although they are equipped with USB-C interfaces, different versions of the iPhone 15 series use different USB protocols.
Among them, the higher-positioned iPhone 15 Pro series will support USB 3.2, and the two iPhone models with lower positioning will support the USB 2.0 protocol. The Lightning interface in the iPhone now uses the USB 2.0 protocol.
In terms of device performance, different USB protocols will bring differences in transfer rates, which will provide different user experiences.
If the content mentioned in the revelation information is accurate, then there will be different transfer rates between the four iPhones this year.
Related news has also mentioned that the iPhone 15 Pro series, which will be unveiled this year, is expected to upgrade the image again, equipped with a periscope lens that supports 5x optical zoom. The core specifications are also expected to be upgraded across the board, but it seems that only two devices with high-end positioning can be equipped with the latest chip version.
At the same time, Apple will also change the button design in the new generation of iPhone 15 series. However, it seems that only the iPhone 15 Pro model uses a capacitive button area design, and the two models with a slightly lower positioning will continue the scheme of physical buttons.
In this regard, Apple is expected to continue to expand the specification differences between different positioning devices in this year's iPhone series to further clarify device positioning.
