On September 7th 2023 Apple introduced the iPhone 15 with USB-C, and CalDigit customers have been asking us if our docks are compatible.
The answer to that question is that all CalDigit Thunderbolt 4 and USB-C docks are compatible with the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max.
The TS4, Element Hub, SOHO Dock, USB-C Pro Dock, and USB-C HDMI Dock are capable of connecting an external monitor to the iPhone 15 with USB-C, as well as multiple USB accessories.
The TS3 Plus can only be used to charge the iPhone 15 via the USB-C port, and the Thunderbolt 3 Mini Docks are not compatible with iPhone 15 due to the PCIe controllers used in Thunderbolt 3 docks.
Check out the chart below to see what is possible when you connect your CalDigit dock to the iPhone 15 with USB-C.
*An external monitor can be supported from the dock’s Thunderbolt port (USB-C), DisplayPort, or HDMI port. A video adapter may be required, such as a USB-C to HDMI adapter.
**The AssistiveTouch feature must be enabled on the iPhone before the mouse can work through the dock.
***The TS4’s 2.5Gb Ethernet is a PCIe based Ethernet controller through Thunderbolt hence it is not supported by the USB-C iPhone. We suggest for you to use a regular USB-C to Ethernet adapter, and attach it to the TS4 so your iPhone can gain a network connection through dock and adapter.
****There are more USB devices that are compatible with the iPhone through CalDigit’s docks such as a USB hub, USB audio interface, USB to Ethernet, USB to SD card reader, and more.
*****Both the iPhone 15 and iPhone 15 Plus support USB 2.0 speeds only while the iPhone 15 Pro and Pro Max can support USB 3.0 10Gbps speeds.
For an optimal experience please have your product name, serial number, and operating system on hand prior to contacting support.
