iPhone 15 Pro (Blue Titanium) and iPhone 15 Pro Max (Black Titanium).
According to BUSINESS INSIDER on September 20, 2023, the iPhone 15 Pro and iPhone 15 Pro Max will be the focus of the iPhone 15 series. The iPhone 15 Pro Max has a titanium alloy body, a high-speed USB-C interface, and the iPhone 15 Pro Max has a “5x optical” telephoto lens. Let’s take a closer look at the actual device to see how easy these features are to use.
USB-C” terminal works with a wide variety of common devices
One of the major changes in the iPhone 15 series is the “USB-C” adoption. This is of course used for charging, but it can also be used to connect peripherals without the need for an adapter, expanding the range of applications. In particular, it will be interesting to see if the devices that have been previously provided for Android and PCs will work. Therefore, I tried connecting various USB-C (USB Type-C) compatible peripherals that I have on hand. As it turns out, most of them work without any problems. USB memory stick SD card reader USB microphone High-resolution USB audio DAC Ethernet adapter HDMI cable The above list was used with iPhone 15/15 Pro without any problems at all. No driver software or other software is required.
Be careful with “cables” for display connections and high-speed transfers
Of course, the iPhone 15/15 Pro could be connected to a PC display using a USB-C cable. However, when connecting to a display, you will need a cable that supports DisplayPort Alt mode, or technically speaking, a cable that supports USB 3.2 or Thunderbolt 3 or higher. The USB-C cable included with the iPhone 15/15 Pro series is compatible up to “USB 2” and is not compatible with display connections. This point should be noted. Similarly, for high-speed data transfer with the iPhone 15 Pro, a separate cable that supports USB 3 (USB 10Gbps in the USB-IF notation) is required. Note that we tried to connect a storage device with a faster M.2 SSD (2TB), but it was not recognized properly. The reason was “power consumption.” When connecting a USB-C peripheral device to the iPhone, its power consumption must be less than 4.5 W. The M.2 SSD was not recognized because of its high power consumption. A separately prepared high-speed, high-capacity SSD (“SPE-USC500” from I-O DATA DEVICE, 500GB capacity) was recognized, so it appears that there is a delicate balance between speed, capacity, and standards. If you are going to connect a high-capacity SSD to the iPhone 15 Pro for video recording or other purposes, you should probably prepare a type of storage that is connected externally for power.

What is the E-Marker chip?
The USB-C charging cable connector has a chip called an E-Marker (Electronic Marked Cable), similar to the charging cable’s security ID card. This is actually a protocol controller feature that monitors the charging status and helps to properly allocate the current.
Most USB-C charging cables on the market today have specifications of 3A and 5A. According to USB-IF Association regulations, if the current output of the power adapter exceeds 3A (100W) or 5A (240W), an E-Marker chip must be incorporated to ensure that charging occurs under a safety protection mechanism. The following table distinguishes these E-Marker cables according to various parameters
