In a recent research report, KGI analyst Ming-Chi Kuo mentioned that the three iPhones that Apple will release this year will still use the Lightning interface, but Apple will add a fast charging function to them.
In the past two years, USB-C interface has been popularized in mobile phones. In the computer product line, including Apple's own MacBook Pro also uses this interface, the industry had previously rumors that in the iPhone 8 Apple will also use the Lightning interface used for many years, switch to USB-C.
However, Guo Mingyi mentioned in his research report:
The new 2h17 model (referring to the 2017 iPhone) can support fast charging. We believe that all three new iPhones will use Type-C power transmission technology (while still maintaining the Lightning interface appearance).
A key technical challenge is to ensure product safety and data transfer stability during fast charging. To achieve this goal, we believe that Apple will use Texas Instruments' power management and the Cypress power OLED version of the iPhone (the legendary high-end version) may adopt a 2-cell L-shaped battery, as well as faster charging speed.
In addition to quick charging, along with the iPhone 8, there are OLED curved screens (at least one is), a special camera, and may even have wireless charging capabilities.
Apple's fast charge
The reason why using Lightning, in addition to many years of habit, there is an important reason is that Apple wants to maintain the benefits of MFi certification license accessories.
In fact, it is not fast charging, and the relationship with USB-C or microUSB interface is not great. The main problem is fast charging while keeping the phone stable.
Apple always maintains a cautious attitude toward new technologies "from the lab to the product". This is the reason why the hardware configuration of the iPhone is not as beautiful as the Android phones. The technology like the 2K screen is quiet after the popularity of the Android camp for a while. However, it has never appeared on the iPhone.
Take USB 3.0 as an example. Many years ago, Samsung added a USB 3.0 interface to GALAXY Note 3. However, when transferring files at a high speed, there will be signal collision problems. Users of N9008V (mobile 4G version) often encounter mobile phone connection to the computer. When the file is in use, the 4G signal of the mobile phone will be suddenly interrupted and automatically transferred to 3G/2G mode. This is the interference generated by USB 3.0 to the 2.4 GHz band network.
It is also for this reason that at present, although there are many manufacturers using USB-C, only a few manufacturers have truly achieved USB 3.0 transmission, and many manufacturers still use USB-C+2.0 as the transmission speed. One of the founders of mobile phone Liu Zuohu once In an exclusive interview, it was considered that mobile phones are mainly based on wireless transmission. There are not many opportunities for computers to transmit big data like U-disks, so USB 3.0 is not necessary.
on the other hand. Apple is very cautious about the use of fast charging. At present, only AirPods headphones are used in many product lines. The Magic Mouse second-generation mouse uses a fast charge. In the large-sized products, only the 12.9-inch iPad Pro can already support the USB 3.0 transmission speed and speed. Charging, but the line is not available, you must separately purchase Apple's own USB-C to Lightning data cable to be able to, iPhone and other devices used Lightning transmission or USB 2.0 speed.
