The new iPhone 15 Pro has improved in many aspects, one of them being the physical USB Type C connector. To this must be added the ability to record video in Apple ProRes 4K format at 60 frames per second. But the 128GB iPhone 15 Pro has a handicap, which is that this recording quality is cut if we do not connect an external hard drive or some other type of storage. And in this case, the problem has to do with all of this.
The standard USB type C connection now allows us to connect peripherals without the need for adapters. Now, we must also take into account that the iPhone 15 Pro port supports USB3 speeds, so we will have a data transfer speed ten times greater than what we had in Lightning. So what is the problem? What connects external storage to the iPhone: The cable.
Why the connection cable is important
When it comes to having high-speed connections, there are three elements that must be on par, in order to offer the best possible results. To start, the physical port must support fast transfer rates. Secondly, the storage memory also has to be on the same line, in terms of speed compatibility, as the port where it is going to be connected.
And what unites both? The USB type C cable. Although it often goes unnoticed, the cable is as important as everything else. Not all USB Type C cables are the same, so it’s not enough to just grab a cable and plug it in, regardless of the maximum bandwidth they are capable of supporting.
If we want to connect a slow cable to join two faster devices, or vice versa, the result we expect will not be what we were looking for. And the problem with the iPhone 15 Pro is that, according to what is reported in the 9to5Mac media, it is not going to warn us that the cable we have connected is, in reality, not very powerful.
The iPhone does not warn. So what?
At first it seems like nothing is going to happen. And precisely the fact that nothing happens is what causes the problem. When we want to connect a hard drive to a 128GB iPhone 15 Pro to record in ProRes 4K at 60 fps, and the cable is not enough, this is where the problems begin.
They explain the testimony of a reader, who realized this, when she realized that tEverything he had recorded looked “terrible, with very few frames”. When trying to connect a fast hard drive with a cable that does not support USB3, the amount of data transferred to the hard drive was much greater than the cable is capable of handling.
All this would not have been a problem in use, if the Camera application or the iOS interface itself had warned in time. And there was no warning that the cable was incompatible with the transfer speed.
