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 foremost digital camera, permitting it to seize the most important 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 possibly can create far more detailed picture information and better decision images with that large sensor, there was no improve to the info switch pace of the USB 2.0 Lightning port.
Lightning is slowwwwwww
As any content material creation skilled has skilled, transferring photos and video out of your iPhone to your Mac utilizing a Lightning cable is agonizingly gradual. First, the Pictures app has to synchronize and index the file listings and thumbnails, which takes some time. Then it’s important to do an import process.
When you have 100 75MB ProRAW pictures (7500 MB) it’s good to switch out of your iPhone 14 Professional, it would 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 might be roughly 30GB. At that price, it might take you 8 minutes to switch that a lot knowledge over a Lightning cable. If you’re utilizing the Pictures or iMovie database to retailer them, the indexing might take considerably longer, as it isn’t only a easy copy from a mounted file system, and there might 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 end up on the iPhone Improve Program, in need of mortgage termination funds, you successfully swap one month-to-month fee for an additional. However I’ve to say that it was not as large of an enchancment as I appreciated as a result of, as a meals photographer, it didn’t enhance my inventive content material workflow or productiveness in any respect; the info switch was as gradual 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 quite a lot of rumors and spy images about what elements are on account of be upgraded (the digital camera 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 are able to count on from the cellphone.
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 complete 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 as we speak — 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 instances enhance over USB 2.0 switch charges.
USB 3.2 Gen 2 on an iPhone might 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 might 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’ll additionally enable for elevated wattage and, thus, sooner charging speeds.
Third-party Lightning cables are licensed underneath 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 (equivalent to transportable energy stations) as a possible substitute 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, based on latest rumors. That is even sooner 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 shoppers to standardize on a single cable kind. 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 acquired 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 interested by machine security or potential switch pace. Nevertheless, I’ve additionally purchased from trusted suppliers equivalent 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 collection has all of the choices
That pack of $15 Amazon Fundamentals USB-C cables launched in 2020 that I purchased for primary charging wants discounted on Prime Day must 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? In all probability 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 sooner speeds should you purchase their USB-IF licensed $35 USB4/Thunderbolt cable with a comparatively low bend lifespan, so it will not be your day by day driver for charging.
Anker’s best-selling $16 Powerline III can deal with a 100W load, making it a great cost cable, however you will not be capable to transfer knowledge sooner than USB 2.0. So, as a content material creator, you may want a number of high-end cables round strictly for knowledge switch.

USB-IF or MFi?
It will result in a sure diploma of shopper confusion as a result of many of the cables presently within the gross sales channel offered by most third events should not marked as to what wattages and switch modes they help — it is already problematic after we take into consideration machine connectivity and cost charges within the Android and Wintel laptop computer ecosystem.
Apple’s OEM cables might be trusted with its personal gear, and its USB-C and Thunderbolts are safely interchangeable (though there is a large value distinction between the 2, and Thunderbolt might be overkill to be used strictly as a charging cable.) However as to the remainder of the business?
Additionally: Why some persons are shopping for MacBook Execs with damaged shows
In 2021, the USB Implementer’s Discussion board created new logos for licensed options underneath 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 offered in retail, equivalent to Anker’s USB4 40Gbps talked about above. And plenty of aren’t licensed; they merely say “240W” and don’t use the official USB-IF emblem.
USB Implementer’s Discussion board
Apple has to this point not stated if it’ll undertake these logos for its MFi merchandise or on the iPhone packaging and machine, and we additionally do not know if there might be elevated adoption of USB-IF logos by Third-parties now that the iPhone will totally 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 might extra than simply irritate the EU), subject a scary warning, or will it cost and switch knowledge at slower charges?
So which label on a cable turns into extra necessary now, MFi, or USB-IF? Discuss Again and Let Me Know.
