These complaints aren’t without merit: even Apple-authorized Lightning cables do break, which is particularly infuriating given how expensive they tend to be. But there’s a lot of bad information about Lightning cables floating around right now, and having spent a lot of time using them and reading user complaints, I wanted to help people avoid some of their preventable failures. Taking a few precautions can save you a $10 to $20 replacement cost, as well as wasted time and stress…
One thing I’ve noticed about Lightning cable failures (and reports of Lightning cable failures) is the consistent places where they’re happening: many occur at the junction point between the Lightning plug and the soft plastic cable, some impact the Lightning plug’s pins, and relatively few are at or near the USB port. The reasons are a combination of strain, corrosion, and — in some cases, but fewer than one might think — shoddy manufacturing.
As a general rule, legitimately Apple-authorized Lightning cables don’t sell for less than $8; apart from Amazon’s cables, relatively few are less than $10. If you’re getting a cable for less than that, even if it’s claimed to be an authentic Lightning cable, you can automatically assume that corners were cut when making it, and that you’re taking on a higher risk of a failure that’s not (entirely) your fault. By comparison, strain and corrosion typically are your fault. Yank on a cable, pull it from both sides, or let it make contact with liquids — very few cables are going to be able to withstand that sort of (ab)use. So here’s what you can do to keep your cables working.
(1) Grasp the hard plastic jacket, and only the hard plastic jacket, when connecting and disconnecting the Lightning plug. Apple touted the Lightning connector as more durable than the 30-pin Dock Connector it replaced. And the connector is indeed more durable — after testing tons of cables, I have yet to see an authorized Lightning plug or even the hard plastic jacket around it come apart. But the cabling itself is made from a softer plastic that can detach from the connector. If you grip the hard plastic jacket when plugging and unplugging the Lightning connector, you’ll considerably reduce the likelihood of cable failure.
(2) Don’t strain or kink the cable. Lightning cables are almost all coated in soft plastic (rarely in resilient fabric), but regardless of their exteriors, they contain bundles of thin wires that can break — invisibly. If you stretch a cable to its maximum length and tug, put a bunch of sharp bends into the center of the cable, or knot it, you may see what appears to be elastic, rubbery flexibility outside, but the metal inside is preparing to snap. Apple’s cables and most others have “strain relief” points between their plugs and cabling, but they’re only “relief,” not cure-alls. Avoiding sharp bends in the Lightning cable and tugs on the ends will keep your cable working longer.
(3) Keep the pins clean and away from liquids of any kind. If you want to criticize the Lightning standard for any design flaw, its use of exposed pins (versus the metal jackets found on micro-USB and USB-C) would be the easiest target. Exposed pins are easier to scrape off, damage, or splash with a stray soft drink droplet causing corrosion. Any of these things could easily happen if a Lightning cable is used in a car near a cup holder where keys, coins, or beverages are often found. Jacketed pins aren’t immune from these issues, but they’re less likely. The best thing you can do is keep the pins clean — both on your cable, and on the device you’re using with the cable. Dry off any moisture immediately, and make sure nothing has gotten into your iPhone, iPad, or iPod’s Lightning port that might mess up the connection.
If you’ve followed these guidelines and your cable has failed, don’t hesitate to contact the cable’s manufacturer for a replacement. Your warranty period will depend on the cable’s own warranty, the country where you live, and — if it’s an Apple product — whether you have AppleCare, which might well have extended the warranty’s duration by a year. If you’re completely out of luck with the cable, vote with your pocketbook and buy a replacement from another company instead.
