USB-C on iPhone 15: This is why it changes the situation much more than you think

I replaced my iPhone 13 pro Max from last year with the iPhone 14 Pro Max ? Yes, because when you participate in the iPhone upgrade program, apart from the end of loan payments, you actually exchange monthly for another. But I must say that it was not such an important improvement as I wanted because, as a culinary photographer, it did not improve my creative workflow or my productivity at all; data transfer was as slow as it had always been.

USB-C on iPhone 15: This is why it changes the situation much more than you think

Technology: IPhone passage to standard load and data connector has serious implications for the wiring accessories industry. here’s why.

By Jason Perlow | Friday 01 September 2023

Last year, at the same time, I was not very enthusiastic about the release of the iPhone 14 Pro. Despite the impressive improvements made by the 48 MP sensor of the main camera, which allows you to take the biggest and detailed photos ever made on an iPhone, and the superb 4K videos at 24 or 30 images per second in second kinematic mode with optical zoom, I was hungry.

For what ? The data transfer of data from the USB 2 Lightning port.0 has not been improved.

Lightning is super slow

Like any content creation professional has experienced it, the transfer of images and videos from your iPhone to your Mac using a Lightning cable is disconcerting slowness. First of all, the photos application must synchronize and index the file lists and the vignettes, which takes a while. Then you must carry out an import procedure.

If you have to transfer a hundred proraw photos from 75 MB (7500 MB) from your iPhone 14 Pro, this can take you more than two minutes at around 60 mega -typles per second (MB/S), assuming that the transfer rates are optimal.

A 4K Prores video clip from five minutes to 6 GB per minute represents around 30 GB. At this rate, you will need 8 minutes to transfer this amount of data via a Lightning cable. If you use the photo database or iMovie to store them, indexing can take much more time, because it is not a simple copy from a mounted file system, and there will be Protocol overload.

I replaced my iPhone 13 pro Max from last year with the iPhone 14 Pro Max ? Yes, because when you participate in the iPhone upgrade program, apart from the end of loan payments, you actually exchange monthly for another. But I must say that it was not such an important improvement as I wanted because, as a culinary photographer, it did not improve my creative workflow or my productivity at all; data transfer was as slow as it had always been.

A USB-C iPhone has all the necessary potential

It was last year. At a time when I write these lines, there are only two weeks left before the launch of the iPhone 15. If many rumors circulate on the components that should be improved (the camera should in particular integrate a new “periscope” design for better optical zoom), very little is “confirmed” with regard to what we can expect of this smartphone.

We do not yet have all the specifications to find out if the iPhone 15 models have been upgraded to the USB 3.2 or USB 4. Regarding the current Apple product portfolio, the latest USB-C iPads have USB 3 connectivity.2, while current iPad Pro models have Thunderbolt 3/USB-4.

USB 3.2 Gen 2 is fast

USB 3.2 Gen 2 is fast. The theoretical upper limit is 10 Gbps, and USB 3.2 Gen 2×2, that no smartphone supports today – only laptops – is 20 Gbps.

According to a comparison of suppliers, the Samsung Galaxy S23 Ultra is equipped with the USB 3.2 Gen 2, a reference for Android devices of the current generation.

And USB 4/Thunderbolt 3, the same as that used on the Ipad Pro and current Macs ? 40GBPS or 5,000MBPS per second, an increase of more than 80 times Compared to USB 2 transfer rates.0.

USB 3.2 Gen 2 on an iPhone will be a welcome change, which will put it on equality with the fastest Android devices. But if we get USB 4 on any iPhone 15 model, it will be a real upgrade and a leap forward compared to Android in terms of connectivity speeds of the connectivity speeds devices.

Other advantages, but also challenges

Data transfer speed will not be the only advantage of USB-C on the iPhone; It will also increase power and, therefore, accelerate loading speeds.

Lightning thirds cables are certified as part of the Apple MFI program for a maximum power of 18 W, which limits the load speeds of the USB PD. USB PD via a USB-C cable supports up to 240 W for desktop computers and other small devices (such as portable power stations).

I do not expect that an iPhone is in charge of 240 W, but it could reach 35 W, according to recent rumors. It is even faster than the current generation of iPad pros, which is responsible for 20 W.

An iPhone with the same charging connector as other devices will allow consumers to use a single type of cable. But all USB-C cables are not built in the same way or do not support all transfer speeds and power limits.

USB cables will be less and less interchangeable

We all have USB-C cables with USB-C scattered in our homes, and so far I used them in a fairly interchangeable way without thinking about the safety of the device or the potential transfer speed. However, I also bought cables from trust suppliers such as Anker, Nomad and even Apple (to recharge my MacBook Pro and my iPad Pro).

The Amazon Basics USB-C cable at € 11, marketed since 2020, which I bought for my basic charging needs should be correct, because it has a nominal power of 60 W and supports the USB 3.1 Gen 2 (10 Gbps). But a cable supplied with a cheap Chinese lighting gadget that I put in my cable box and that I use from time to time ? Probably not.

And it is not because a cable supports a load rate and a rapid power that it is compatible with the USB 3.2. For example, anker cables only support higher speeds if you buy them USB-IF certified with a relatively low lifespan, which means that they will not serve you on a daily basis for recharging.

Anker’s best -selling cable can support a 100 W load

The best -selling cable from Anker can withstand a 100 W load, making it a good load cable, but you will not be able to transfer data faster than with the USB 2.0. As a content creator, you will therefore need a few high -end cables only for data transfer.

USB-IF or MFI ?

All this leads to some confusion among consumers. Because most of the cables currently sold have no indication for the powers and the transfer methods they take care of.

Apple OEM cables are reliable, and its USB-C and Thunderbolt cables are safe interchangeable (although there is a large price difference between the two, and Thunderbolt is too expensive for strictly use as cable dump). But in terms of the rest of the industry ?

In 2021, the USB implement forum created new logos for certified solutions. Until now, the adoption of these logos has not been generalized on the cables sold to retail, such as the USB4 40 GBPS of Anker mentioned above. And many are not certified; They simply indicate “240w” and do not use the official USB-IF logo.

USB implementation forum

Apple has not yet indicated whether it would adopt these logos for its MFI products or on the packaging and the iPhone device. We also do not know if the USB-IIF logos will be increasingly adopted by third parties now that the iPhone is taking charge of the USB-C.

More importantly, we do not know what is happening either when a non-MFI USB-C cable (without the Apple license authentication) is detected by the iPhone 15. Does he refuse to operate (which would not fail to irritate the EU), does it emit a scary warning, or will he load and transfer data to slower speeds ?

So what label on a cable is the most important today, MFI or USB-IF ?

To make their wage demands heard, unions call for the mobilization of store employees.

iPhone 15: connect it to an Android smartphone in USB-C and here is what’s going on

Now that the iPhone has finally gone to the USB-C, it’s time to connect them to a whole bunch of devices to see what happens. Let’s start with the most obvious: an Android smartphone. The result is not quite the one we expected.

iPhone 15: connect it to an Android smartphone in USB-C and here is what’s going on

Among all the new features that the iPhone 15 bring, one of them has caused a lot of ink. However, it has been a standard at Android for many years: the USB-C port Of course. The change is notable, especially as that of the iPhone 15 is not a connector like the others. He still opens the way to a lot of possibilities, such as recharging his AirPods or his Apple Watch with an Apple smartphone.

But there is an obvious affair that we want to test immediately. You surely think about it too: Connect an iPhone 15 and an Android mobile in USB-C. It is now very easy since there is no longer any need for any adapter. The YouTube channel team Petapixel Experience in a short video. According to their speech, we just know that they have a iPhone 15, not More Or Pro, and one Google Pixel without precision of the model. We still assume that it is Pixel 7 or Pixel 7 Pro. Cable specificities are not given either.

What happens when you connect an iPhone 15 to an Android smartphone in USB-C ?

We see it in the video, as soon as the two devices connected to each other, The pixel begins to take care of the energy of the iPhone 15. The behavior then changes camp since by disconnecting and reconnecting the cable, Apple’s mobile is finally loading thanks to the Android phone. The choice of priority is not clear and the two youtubers do not push the experience further.

Then, as you would expect, The transfer of files between the two devices is impossible. Everyone does not appear in the list of the recipients of the other. It will be necessary to wait for more exhaustive tests to know if there is a logic behind the observed phenomena and whether it is possible to influence it, whether depending on mobile models or USB-C cables used.
