Hi guys,
I’m on a 14 pro max, I tether internet via cable on the go as it give’s me a faster speeds.
Will the USB-C on the 15 make a difference?
No difference as USB-C on iphone 15s (not the pros) are still using USB 2.0 speeds i.e 480 mbps
The USB-C port on the iPhone 15 (non-Pro) is limited to 480Mbps. Theoretically this is the same as the lightning port speeds. This is because the non-Pro 15 models are running the A16 processor and controller.
iPhone 15 Pro/Pro Max can support transfer speeds up to 10Gbps. But, you need the right cable. The one that comes with the phone in the box, and most USB-C charging cables, only support USB2.0 data speeds (480Mbps). You need a USB 3.1 Gen2 certified cable to get the full transfer speed out of the 15 Pro/Pro Max port.
Note that such cables tend to be kinda short… usually around 3 feet max.
Will it make a difference? That really depends on your wireless carrier. In some isolated cases I can exceed 480Mbps on Verizon and AT&T when I can get ultra Wideband 5G. Most of the the time I’m not hitting that limit though. And that’s on-device speeds. Tethered (hotspot) speeds are always de-prioritized.
I used a random choetech 3usb 1ethernet to 1usb-c dongle and I was getting 900+ mbps
