When you’ve purchased one among Apple’s late 2023 telephones (and gone by our record of the primary 7 issues to do with it) you’re in all probability questioning concerning the new port on the backside. The Lightning port, which arrived on the iPhone 5 in 2012, has lastly been changed by the non-proprietary USB-C customary, which implies it’s appropriate with a wider vary of cables, chargers, and different equipment.
However what particularly can the brand new USB-C port be used for? What are its charging and information switch speeds? What different merchandise is it appropriate with, and does it carry out higher with official Apple-certified equipment? On this article, we define the capabilities and limitations of USB-C within the 15-series iPhones.
Charging
By far the commonest use of your iPhone’s USB-C port can be for wired charging, which is quicker and extra power-efficient than charging wirelessly. MagSafe is capped at 15W, whereas charging through a USB-C cable ought to be capable of obtain 20W or extra (relying in your iPhone mannequin and different bottlenecks).
You’ll want a USB-C cable and a appropriate energy adapter. (The 15-series iPhones every include a cable with USB-C on each ends, however no energy adapter. You’ll must present that your self.) The brand new iPhones are able to quick charging–or what Apple describes as quick charging, there being no broadly agreed customary for what which means–however you’ll want an influence adapter rated at 20W or greater. When you can set that up, Apple claims the iPhone 15 and 15 Professional will cost as much as 50 p.c capability in half-hour, and the iPhone 15 Plus and 15 Professional Max in 35 minutes.
In reality, Macworld testing (utilizing the bundled cable and a high-powered 67W MacBook energy adapter) suggests Apple is being considerably modest concerning the charging velocity restrict: our pattern iPhone 15 Plus had reached 64 p.c cost after the required 35 minutes. It took 92 minutes to utterly cost from empty.
The iPhone 15’s USB-C cable can do much more than the older Lightning fashions.

Reverse charging
It is a new functionality for the iPhone line: the 15-series handsets can themselves cost up different, smaller units. Join your iPhone 15 to an Apple Watch, an AirPods case, or one other appropriate product, and energy will circulate within the different path. (So be sure the iPhone has sufficient cost to soak up the hit.)
For this operate, you in all probability gained’t want to purchase any additional cables. Present and up to date Apple Watch fashions include charging pucks which have USB-C on the opposite finish, and you may simply cost your AirPods utilizing both USB-C to USB-C or USB-C to Lightning, relying on which case you’ve obtained.
On a technical degree, reverse charging is slower than common charging. Apple says you’ll want the small system to assist USB Energy Supply at as much as 4.5W. However with such units, even a comparatively small switch of cost could make all of the distinction. In testing, we discovered that simply quarter-hour of reverse charging was sufficient to bump an Apple Watch Sequence 8 from 53 p.c to 68 p.c, whereas the linked iPhone 15 Plus dropped from one hundred pc to 97 p.c. You’re gaining a couple of level per minute, whereas the losses on the iPhone facet are proportionately far smaller.
Connect with iPad, Mac, or PC
Information switch, like charging, is faster in case you use a cable. AirDrop could also be extra handy, however when batch-transferring pictures and movies out of your iPhone to your Mac, for instance, we’d advise plugging them in. Most fashionable Macs and all present iPads have a minimum of one USB-C port, so you possibly can join your iPhone utilizing the USB-C cable from the field, although your mileage could differ with PCs.
Switch speeds differ relying on whether or not you paid additional for a Professional mannequin. The iPhone 15 and 15 Plus assist the USB 2 customary, which has a theoretical restrict of 480Mbps. The 15 Professional and 15 Professional Max, in the meantime, assist USB 3 and, assuming you’ve obtained a USB 3-compatible cable to benefit from this, speeds of as much as 10Gbps. (The cable provided by Apple tops out at 480Mbps.)
As an added bonus, your iPhone will cost whereas connecting to one among these bigger units.
Connect with an exterior storage system
Like transferring information to an iPad or Mac, the iPhone 15 also can hook up with exterior storage drives. In reality, when you’ve got a 128GB iPhone 15 Professional, you need to report on to an exterior drive with a purpose to report 4K ProRes movies, which take up oodles of gigabytes. Larger configurations don’t have this limitation and might save ProRes video on to the system.
Connect with shows and TVs
The USB-C customary makes it a lot simpler to attach your iPhone to a TV, monitor or different show, and consider your pictures and movies on a bigger display. Nevertheless it isn’t essentially as simple as plugging in a cable.
If it’s a USB-C show, after all, you should utilize an ordinary USB-C cable to attach the iPhone to the show. (Apple says the 15-series iPhones use DisplayPort to assist as much as 4K and 60Hz on appropriate shows.) If you wish to profit from excessive resolutions, nevertheless, you’ll need to use a cable that helps USB 3.1 or greater. A USB-C show could additionally cost a linked iPhone, however this varies from mannequin to mannequin.
If the show or TV is predicated on HDMI, you’ll want some kind of adapter (resembling Apple’s personal USB-C Digital AV Multiport Adapter – US retailer hyperlink/UK retailer hyperlink) or a USB-C to HDMI cable. Supplied your cable/adapter helps HDMI 2.0, the iPhone will be capable of output video at 4K and 60Hz.
Both approach, whenever you hook up with an exterior show the iPhone will default to exhibiting what’s by itself display. The exception is whenever you’re utilizing an app that encompasses a “second display” mode, however these are rather more widespread on the iPad.
The iPhone 15 can hook as much as an Apple Studio DIsplay with only a USB-C cable.

Connect with audio units
The iPhone 15 can hook up with a variety of audio equipment which might be appropriate with USB-C, whether or not enter units (resembling microphones) or output (resembling audio system or headphones). For some audio units, chances are you’ll must get a USB-C to three.5mm jack adapter.
Connect with different units
The USB-C customary is astonishingly prevalent, and chances are you’ll be stunned by the vary of equipment now you can hook up with your iPhone 15 with out having to pay the “Apple Tax” for a Lightning-compatible or Apple-certified model. This contains exterior battery packs, SD adapters and therefore SD playing cards, ethernet adapters, and even automobiles (though they nonetheless must be CarPlay-compatible). In all of those instances, keep in mind that information switch, if relevant, can be quicker in case you use an iPhone 15 Professional or Professional Max, and a cable/adapter/accent that helps USB 3.0.
You possibly can even join Lightning equipment to your iPhone 15… though in that case, you’ll want a dongle. Plus ça change.
