![]() These early failures of these charging/data cables must be severely adding land fill, resource usage and is not acceptable when it is considered the vast number of phones etc out there. Which is probably what is happening also with a too thin layer of gold exacerbated by the higher current draw on that terminal. Very careful cleaning can return the functionality of the cable but probably won’t last long as the gold plating will probably be perforated to the underlying much more easily oxidisable probably copper layer. It needs someone to investigate the thickness etc of the gold plating etc eg is the gold plating thickness inversely proportional to the rate of the problem. With the lightning cables though this problem for me has occurred on the more expensive cables eg apple ones. From a visual inspection looked as though the gold plating was thicker though it may also be that the terminal under the gold plating maybe better quality lower resistance and possibly with less heating. Advised by the supplier of the equipment to try a higher quality cable which had superior connection terminals. I had the same problem with normal Ethernet cables in a higher than normal power draw application. From that one could infer that it could be the thickness of the gold plating. L0vetodream suggests Apple will start using this cable. You could well be right…,also I thought these connections were all gold plated… I have several cables but this problem does not occur on all of them. The 2019 Mac Pro already comes with black braided Lightning to USB-C cable, which is probably what is being shown in the photo. ![]() This is certainly true in my cable’s case as I can only charge and sync my iPhone from one side of the cable as other ones doesn’t work at all making the problem particularly annoying. In many cases when the pin becomes black, one side of the lighting cable stops working. You are welcome to comment below about the result, if you give it a try. We haven’t tested his solution of cleaning the cable with alcohol so can’t confirm if it works. He goes further by suggesting to clean the cable with alcohol, which may make the black side of the cable functional again. Since the electric current is able to jump between the plates easily, this overtime causes the copper to erode, making the pin appear black. The likely cause for this is due to a capacitor charging and drawing more current for a fraction of the second. When the connector is plugged into the iPhone or iPad’s lighting port, there can be a small spark gap that happens when the cable is connected with the device. He explains that the pin or the ‘terminal’ either has a positive or negative voltage connection. According to the user it is a common electrical phenomenon. Luckily another Reddit user who introduces himself as an electrical engineer explains the reason behind 4th pin turning black from gold. Why Fourth Pin On Lightning Cable Becomes Black Turns out it is something that is quite common and many people have seen lightning cable corrosion judging by the respondents on the Reddit post. Photo: Cult of Mac Deals Sometimes it’s about quality, not. After reading his post and looking at the picture that he shared of his cable, I looked for one of my older iPhone cables that had the similar black spot. 29) This USB-C to Lightning cable is perfect for connecting your iPhone to your MacBook. Today I stumbled upon a Reddit post in which a guy asked the community why does his lightning port’s 4th pin has turned black. Over the years we have all had lightning cables that have shown burn marks and black pin. This durable cable is Apple MFi certified and backed by ’s 2-year Warranty to ensure dependable performance.Have you ever had a lightning cable whose 4th pin (or 5th depending on which side you are counting from) turns from golden color to black? If yes, then you are certainly not alone. Plus, the reversible 8-pin Lightning connector can be plugged into your iOS-enabled device with either side facing up, meaning there is no wrong way of inserting the cable into the device. Perfect for close-range device connections, our shorter Lightning USB cables provide a portable solution that makes them perfect for carrying as a laptop accessory.
