@Hank G ☑️ @fne8w2ah It appears to be due to a combination of spark erosion of the centre pin, as lightning is prone to, ironically, arcing on connection and disconnection, as well as electrolysis over time, with the pin eroding and electroplating the connector inside the phone.

The first problem can be rectified by never hot plugging, but if you live in a humid climate, there’s nothing you can do about the second.

Indeed, while the ports last longer than the cables, they eventually fail from being coated with all that crap. Before I switched almost entirely to inductive charging and wireless CarPlay, an iPhone’s lightning port for me rarely made it to two years before dying.

I loved magsafe for the first couple years I used it; then I started to see them fraying & breaking at the connector. It was almost the rule. (I ordered power bricks for Macs for an ad agency for about 8 years, so I saw this a lot.)

Mind you *mine* never went out, so I think this was a user behavior thing, but I would say they were poorly designed for the behavior of most of my users.

Thinking back on this & remembering that at some point Apple redesigned the connector to address this & it...didn't get any better. I.e., they misidentified the cause, which I now think was probably more to do with the materials used in the cable wrapping & "boot" than in the angles or stresses. So, maybe not engineering so much as materials.

@heluecht @fne8w2ah It must be VERY climate specific or people specific. I’ve never had one fail from the connector. Ever. Occasionally they start to wear at the rear of the plug and a bit of sugru fixes that. I’ve cut up and thrown usb a/b cables and usb c cables but never a lightning cable. And all the connectors in all the phones I’ve and still work too!

@fne8w2ah #Apples #Lightning Connector was shit from day 1 and had 0 reasons to exist - unlike the original #DockConnector, but even then the #iPod could've used #MiniUSB or #MicroUSB + #AV-Chinch and #MHL to do Audio & Video.

#MagSafe is also another #proprietary #SingleVendor solution when #Qi+ existed for over a decade.
