This time final yr, I used to be unenthusiastic in regards to the launch of the iPhone 14 Professional. Regardless of spectacular enhancements with its 48MP sensor on its important digicam, permitting it to seize the largest and most detailed images but on an iPhone, and gorgeous 4K video at 24 or 30 fps in Cinematic mode with optical zoom high quality, I yawned.
Additionally: Each product we’re anticipating at Apple’s fall occasion (and what will not be unveiled)
Why is that? Though you could possibly create way more detailed picture information and better decision images with that massive sensor, there was no improve to the information switch pace of the USB 2.0 Lightning port.
Lightning is slowwwwwww
As any content material creation skilled has skilled, transferring pictures and video out of your iPhone to your Mac utilizing a Lightning cable is agonizingly sluggish. First, the Images app has to synchronize and index the file listings and thumbnails, which takes some time. Then you need to do an import process.
When you’ve got 100 75MB ProRAW pictures (7500 MB) you want to switch out of your iPhone 14 Professional, it’d take you upwards of two minutes at 480 megabits per second or roughly 60 megabytes per second (MB/s), assuming optimum switch charges.
A five-minute 4K ProRes video clip at 6GB per minute will probably be roughly 30GB. At that price, it might take you 8 minutes to switch that a lot information over a Lightning cable. If you’re utilizing the Images or iMovie database to retailer them, the indexing might take considerably longer, as it is not only a easy copy from a mounted file system, and there will probably be protocol overhead.
Additionally: Apple merchandise you should not purchase this month: September 2023 version
Did I improve to the iPhone 14 Professional Max from my iPhone 13 Professional Max final yr? Sure, as a result of if you find yourself on the iPhone Improve Program, in need of mortgage termination funds, you successfully swap one month-to-month fee for one more. However I’ve to say that it was not as massive of an enchancment as I preferred as a result of, as a meals photographer, it didn’t enhance my inventive content material workflow or productiveness in any respect; the information switch was as sluggish because it ever was.
A USB-C iPhone has all of the potential
That was final yr. As I write this, the anticipated iPhone 15 launch is simply two weeks away. Whereas there are a whole lot of rumors and spy images about what elements are attributable to be upgraded (the digicam is suspected to include a brand new “periscope” design for improved optical zoom, amongst different issues), little or no is “confirmed” by way of what we will count on from the telephone.
However we all know with nearly full certainty that the iPhone 15 will use USB-C. Why is that? As a result of the European Union has decreed that by the top of 2024, all smartphones and tablets should use the identical USB-C connector.
We do not but have the total specs on whether or not any iPhone 15 fashions have been upgraded to USB 3.2 or USB 4. Relating to Apple’s present product portfolio, the most recent USB-C iPads have USB 3.2 connectivity, whereas the present iPad Professional fashions have Thunderbolt 3/USB-4.
USB 3.2 Gen 2 is quick. The theoretical higher restrict is 10Gbps, and USB 3.2 Gen 2×2, which no smartphones help in the present day — solely laptops — is 20Gbps.
Additionally: Apple could also be including USB-C charging to older iPhones now, too
From a vendor comparability, the Samsung Galaxy S23 Extremely has USB 3.2 Gen 2, a benchmark for current-generation Android gadgets.
And USB 4/Thunderbolt 3, the identical used on iPad Professional and present Macs? 40Gbps or 5,000Mbps per second, an over 80 occasions enhance over USB 2.0 switch charges.
USB 3.2 Gen 2 on an iPhone will probably be a welcome change, bringing it to parity with the quickest Android gadgets. But when we get USB 4 on any iPhone 15 mannequin, that will probably be fairly an improve and would leap forward of Android concerning machine connectivity speeds.
Different advantages, but in addition challenges
Information switch pace won’t be the one benefit of USB-C on the iPhone; it is going to additionally enable for elevated wattage and, thus, quicker charging speeds.
Third-party Lightning cables are licensed below Apple’s MFi program for as much as 18W, which limits USB PD cost charges. USB PD by means of a USB-C cable helps as much as 240W for desktop computer systems and different small home equipment (similar to transportable energy stations) as a possible alternative for the old-school 110V AC cable.
Whereas I do not count on an iPhone to cost at 240W, we might see it as excessive as 35W, in response to latest rumors. That is even quicker than present technology iPad Execs, which cost at 20W.
Additionally: Can an up to date iPad Professional revive a moribund pill market?
An iPhone with the identical cost connector as different gadgets in its family will enable customers to standardize on a single cable sort. However as we all know, and as my ZDNET colleague Adrian Kingsley-Hughes identified final yr, not all USB-C cables are constructed the identical or help all switch speeds and wattage limits.
The newest iPad acquired a USB-C improve, on the expense of this concoction.
We have all obtained USB-C to USB-C cables strewn round the home for various gadgets and equipment, and up till now, I’ve used them pretty interchangeably with out enthusiastic about machine security or potential switch pace. Nonetheless, I’ve additionally purchased from trusted suppliers similar to Anker, Nomad, and Apple’s personal USB-C and Thunderbolt cables (for charging my MacBook Professional and my iPad Professional).
Additionally: Shopping for a USB-C charger for iPhone 15? Anker’s Nano sequence has all of the choices
That pack of $15 Amazon Fundamentals USB-C cables launched in 2020 that I purchased for fundamental charging wants discounted on Prime Day ought to be okay, as it’s 60W rated and helps USB 3.1 Gen 2 (10Gbps). However a random cable that got here with some low-cost Chinese language lighting gadget I’ve stuffed in my box-o-cables that I often attain for? Most likely not.
And simply because a cable helps a quick cost price/wattage does not imply it helps USB 3.2. For instance, Anker’s cables solely help quicker speeds should you purchase their USB-IF licensed $35 USB4/Thunderbolt cable with a comparatively low bend lifespan, so it will not be your every day driver for charging.
Anker’s best-selling $16 Powerline III can deal with a 100W load, making it cost cable, however you will not be capable to transfer information quicker than USB 2.0. So, as a content material creator, you may want a number of high-end cables round strictly for information switch.

USB-IF or MFi?
It will result in a sure diploma of client confusion as a result of many of the cables at present within the gross sales channel bought by most third events should not marked as to what wattages and switch modes they help — it is already problematic once we take into consideration machine connectivity and cost charges within the Android and Wintel laptop computer ecosystem.
Apple’s OEM cables may be trusted with its personal gear, and its USB-C and Thunderbolts are safely interchangeable (though there is a massive worth distinction between the 2, and Thunderbolt will probably be overkill to be used strictly as a charging cable.) However as to the remainder of the trade?
Additionally: Why some individuals are shopping for MacBook Execs with damaged shows
In 2021, the USB Implementer’s Discussion board created new logos for licensed options below its program. Thus far, there hasn’t been widespread adoption of those logos on Third-party cables packaged with many merchandise, solely on the dearer cables bought in retail, similar to Anker’s USB4 40Gbps talked about above. And lots of aren’t licensed; they merely say “240W” and don’t use the official USB-IF brand.
USB Implementer’s Discussion board
Apple has to date not mentioned if it is going to undertake these logos for its MFi merchandise or on the iPhone packaging and machine, and we additionally do not know if there will probably be elevated adoption of USB-IF logos by Third-parties now that the iPhone will absolutely help USB-C.
Extra importantly, we additionally do not know what occurs when a non-MFi USB-C cable (one lacking Apple’s licensed chip for authentication) is detected by the iPhone 15. Does it refuse to work altogether (one thing that will extra than simply irritate the EU), situation a scary warning, or will it cost and switch information at slower charges?
So which label on a cable turns into extra necessary now, MFi, or USB-IF? Speak Again and Let Me Know.
