![]() It's one reason I've been annoyed with the Lightning port on my iPhone. Now, for serious data hogs, the kind of person who's shooting many gigabytes of 4K ProRes video, a faster cable is useful. That's the big reason Apple could mostly justify shipping an iPhone 15 with a USB 2.0 cable. Best USB-C Docks, Hubs, Chargers, Cables and Accessories.Buying a New iPhone 15? Try These USB-C Accessories First.Even as photo and video files have exploded in size with 50-megapixel phone cameras and 4K video, most of us get that data off our phones with mobile networks, Wi-Fi and AirDrop, not with cables. Indeed, iPhone 15 non-Pro phone owners won't be able to benefit from the speeds of a fast cable even if they have one.ĭata rates were more important in the olden days when we used iTunes to sync music and photos between laptops and iPhones. The good news for iPhone 15 owners is that most of them won't have to care much about whether they have a slow cable. When USB-C is a problem and when it's not ![]() A couple of months ago, when I got a new Canon mirrorless camera, I was caught on a trip with slow cables that really bogged down the process of transferring photos to my laptop. Mostly, I use USB-C for charging, and my devices that need fast connections stay attached to their own fast cables.īut problems can happen. I haven't struggled too much with the slow cable problem. (USB's good backward compatibility means slower, older products generally still work fine when attached to newer ones.) Either the manufacturer was confused, lying or trying to argue that the cable would work in a USB 4 port even if it only supported slow data rates. ![]() One affordable cable I saw billed itself as a USB 4 product, but on deeper inspection, it turned out to support only USB 2.0 data transfer. Unlike with Intel's Thunderbolt, which developed the fast data transfer approach in modern USB and uses the USB-C connector, there's no requirement to pass tests. Worse, plenty of device manufacturers trying to cut costs and quickly ship products skip the certification process that the USB Implementers Forum offers. Having three standards - USB, USB-C and USB PD - makes it harder to understand the abilities of all your devices and cables. Most devices don't require that much power, but they do need to know how to negotiate electrical matters - for example, whether a portable battery should charge your laptop or vice versa. Last is USB PD, short for Power Delivery, which governs how USB is used for charging at rates up to 240 watts. The newest USB standard, USB 4.0, requires USB-C ports, so as time goes by, it'll be fairer to equate USB-C with high speed. Earlier in USB-C's history, it was common for Android phones to support only slow USB 2.0 data transfer speeds, though that problem has faded with newer models. The next standard is USB-C, which refers only to the oval-shaped connector technology.
