During the iPhone 15 launch event, Apple revealed the handset’s new USB-C port would have a neat party trick: You can use it to charge accessories like your AirPods or Apple Watch.
The specifications of the connection weren’t revealed at the time, but Apple has now put up a support page covering charging speeds and a few other interesting details. The long and short of it is that iPhone users are about to enjoy a lot more flexibility.
First up, that charging speed. The new port supports USB Power Delivery at up to 4.5 watts, and Apple says this is “to charge your AirPods, Apple Watch, or another small device.”
Support for large external storage could be especially handy with the improved data transfer rates that the iPhone 15 Pro offers. The same support document states that their ports are USB 3.2 Gen 2, offering speeds of up to 10Gbits per second with a USB 3.1 cable (this sadly doesn't include the one in the box, which is USB 2).
Finally, but perhaps most intriguingly, Apple says the iPhone 15 uses the DisplayPort protocol for output to bigger screens, offering up to 4K resolution with HDR at 60fps.
While this will sound like old news to Android users, it’s a big deal for iPhone, as the previous solution required a $49 Lightning adapter, and even then you were limited to 1080p video output. This will again need a USB 3.1 cable, though Apple suggests you use “the cable included with the display” if you don’t fancy paying for another one.
We’re just under a week away from the iPhone 15 reaching early adopters’ hands, with the handsets releasing on Friday, September 22. Look out for our reviews of all four models very soon.
