I love my USB-C iPhone but Lightning was smaller and easier to plug in.

From my experience using various (work provided) devices in outdoors agriculture use, I consider the lightning connector/port less prone to failure as well. If something was to break (from torque), it seems like the tab on the cable should snap or the cable just pull out before catastrophic damage to the port can occur.

Though I still had to replace cables because the cable itself developed a break somewhere, even with one that had proper stress relief at the ends.

Meanwhile most of the USB C ports on my Lenovo laptop from 2022 are barely working because somewhere along the line either the soldering broke or the port got too loose. Possibly from too much torque but I’m not sure. So the cable has to be at just the right angle. I’ve also done some android phone battery/screen replacement for friends, and had to do a few USB-C ports when it was possible due to the same sort of thing.

However all that is pretty much moot now, thanks to wireless charging and magnetic attachment docks. As such the only time I connect a cable anymore is monthly for cleaning out photos and other data. Previously I’d be connecting cables several times a day to charge in between fields as the battery went to shit. Honestly the “MagSafe” concept is the only change I’ve seen to smart phones in the past decade that I actually really like.

  • Lightning had small pins inside the port that could be caught by debris and pulled out of alignment (or in worst cases, broken off altogether). USB-C has no moving parts on the device side. Apple was reportedly behind that design since Lightning was nearing release when design for USB-C started (and Apple is/was a member of USBIF)

    • > Lightning had small pins inside the port that could be caught by debris and pulled out of alignment (or in worst cases, broken off altogether).

      Lightning has 1.5mm of height in the slot, debris has to be pretty large to get stuck and usually it's enough to just blow some compressed air into the slot to get dirt to release.

      In contrast, USB-C has only 0.7mm between the tab and the respective "other" side, so debris can get trapped much much more easily, and the tab is often very flimsy, in addition to virtually everyone sans Apple not supporting the connector housing properly with the main device housing.

Does anyone have reliability data for USB-C ports? It seems to me like Lightning is more robust to repeated plug/unplug cycles. But this is only on my limited sample size of one laptop with a failed USB-C port and some vague hand waving.

  • It shouldn't be, my understanding is that the springy bits (the most likely wear part) in Lightning are in the port, whereas in USB-C they're intentionally in the cable so you can replace it. I'm surprised you have a failed USB port, but I've never experienced one fortunately.

    I see Lightning as fragile on both sides of the connection, since the port has springy bits that can wear, and the cables also die, either due to the DRM chips Apple involves in the mix for profit reasons, or due to the pins becoming damaged (perhaps this? https://ioshacker.com/iphone/why-the-fourth-pin-on-your-ligh... ).

    • USB-C has an unsupported tab in the middle of the port. It's pretty easy for that tab to bend or break, especially if the plug is inserted at an angle.

      Lightning doesn't have that failure mode. Also Lightning ports only use 8 pins (except on the early iPad Pros), so reversing the cable can often overcome issues with corroded contacts. That workaround isn't possible with USB-C.

    • The springy bits never wear out anyway. I've never once seen an iphone that couldn't grip the cable unless the port was full of pocket lint. Main problem I see is USB-C has both a cable and port which are hard to clean.

  • The Lightning port itself might be more reliable, problem is Apple Lightning cables always break, and all third-party ones (even MFi) are prone to randomly not working after a while. I'd be perfectly fine with Lightning if it were an open spec, instead it singlehandedly created the meme of iPhones always being on 1% battery.
