That was one of the main reasons why I sold my Sony headphones and replaced them with Airpods Max. Charging the headphones while in use isn’t really any more inconvenient than using wired headphones would be.

But Apple has alone sold a billion devices using Lightning. Many of those devices will likely remain usable for years.

That’s what I said, wasn’t it?

Thankfully, they recently introduced logo requirements for this exact reason.

In order to pass through the USB-IF Compliance Program, all USB-C® to USB-C cables categories must be labelled with either a power capability of 60W or 240W by using the appropriate power icon and/or logo. The USB-IF now requires that all cables must be labeled with the 60W or 240W logo prior to compliance testing so that testing can confirm the intended display of such icons/logos. The policy now extends to all USB-C to USB-C cables. These markings must be checked before compliance testing can begin.

In addition to the power markings, in order to pass through the USB-IF Compliance Program, all cables except for High-Speed USB (USB 2.0) USB-C to USB-C cables, are required to be marked with the appropriate data rate they can support. An example, a USB 20Gbps USB-C – USB-C cable that supports 20V at 3A must be marked with the Combined Performance and Power 20Gbps/60W logo.

Here's a table of the logos

At least one improvement has been made to the spec over the years: the iPhone X / iPhone 8 introduced support for fast charging through the USB-PD standard which meant something had to be upgraded. I'm fairly sure that change did not result in physical changes to the connector though. It has always remained backwards-compatible.

Apple introduced the Lightning connector with the iPhone 5 back in 2012. At the time, it was reversible and superior to the existing Micro-USB connectors. Having been manufactured of a single piece of metal, it was also more durable than the more complex USB connectors.

The first USB-C phone was released in 2015. Samsung released their first USB-C phone, the infamous Galaxy Note 7 in 2016. Their flagship model didn’t use USB-C until 2017.

I find the whole Lighting-hate thing slightly puzzling. Imagine that you come up with a technological solution that solves a problem. Years later, other people finally find a way to solve the same problem. Then they accuse you of being backward. Finally the use of your solution is declared illegal.

Still, now that iPhone indeed has switched to USB-C, Apple's keyboards, headphones and touchpads should follow suit as soon as possible. It makes no sense for them to use Lightning anymore as the ecosystem around it is obsolete.

Edit: another thing that I have found puzzling is how Apple is getting all the hate for proprietary standards, yet at the same time multiple other manufacturers have developed their own proprietary fast charging protocols which means you need both a proprietary cable and a proprietary charger to charge your phones to get charging speeds anywhere close to what is advertised. This was tested by for example Android Authority a few years back. To provide a more up-to-date example, OnePlus 10 Pro supports fast charging at 65 watts but only with its own ”SuperVooc” charger. If you try to charge through USB-PD, you are limited to 18 watts even though PD would theoretically support up to 240 watts. The SuperVooc chargers also refuse to charge any other device at a power higher than 10 watts. It’s interesting how this phenomenon has slipped under most people’s radar.
