Yes, this cable uses data pins and uses driver because it actually contains hidden chip. So it proves my point.
New malicious Lightning cable can steal user data from a mile away | AppleInsider
A new and upgraded version of a malicious Lightning cable that can steal user data and remotely send it to an attacker illustrates the threat of untrusted accessories.appleinsider.com
It would be interesting to see what the metrics are on battery health at ever-increasing charging speeds. Obviously it’s more complicated than just speed of charge, as the speed is on a sliding scale depending on what capacity percentage the battery is at. But there must be an upper limit that pushes temps beyond a safe level, both for the battery and the rest of the phones components. Like so many other specs that some brands push to have the biggest number, making a battery accept a 100w charge might be fine when sold in small numbers, but it could also have a 20% failure rate that would be brand-damaging for someone like Apple selling hundreds of millions of iPhones each year.
Have you looked to see if there is any app or system process draining the battery?
If your battery is reporting it has 90% capacity but you are seeing you have about half the runtime between charges, those numbers don't line up.
The circles I look at were all blaming iOS 17 for the lower percentages. I'm still at 100% though on my 14 pro (on 17).
I wouldn't expect the maximum capacity calculations to change for previous phones as part of a beta cycle - they would be more likely to update in an iOS 16 release and to lag merging into 17 betas.
I'd be happy to see a message flash up on screen saying both the cable and the adapter are MFI certified, and what wattage you are charging at. You have no idea what kind of crap you're buying for the most part otherwise!
I don't think they'll be able to limit the speed, at least in the EU...

Standards-compliant USB-C cables have at least USB 2.0 data transfer.
Even cables that go non-standard and cut the data pins still have the CEC channel if they support power delivery. CEC is another data channel, and can be used for things like updating device firmware.
USB-C charging cables require an e-marker chip if they support over 30W.
Exactly! And with such MFi is totally not needed and it's just Apple's money grab.
It’s USB-C. You can use “data” cables for charging. In fact I’m using Apple’s Thunderbolt 4 cable to charge my MacBook Pro right now. Connected to the power brick NOT a Thunderbolt hub.
Well this also means I need to replace 7 cables and 5 accessories that are lightning. Not looking forward to that.
And if AirPods don’t get updated with USB-C I’ll have even more cables to deal with.
Data cables are not the same as data pins.
Using data cable does not mean data pins are being using when using charger. They are not being used in such case.
You said there is no issue because "Charging cable is dumb and should not use data pins."
I am NOT using a charging CABLE.....I am using a data cable. So the pins are there.
I am not using this, which is limited to data speeds of USB 2.0 (shocking huh???)

And yes data pins do get used during charging in many scenarios. Ever use the camera adapter for the phone? Or a Thunderbolt dock that charges your iPad at the same time that allows ports to be used?

would love for all phones to be 100w but not realistic. 35w is fine and least it's better than what we have. think 50w should be min in 2023.
You still miss the point.You said there is no issue because "Charging cable is dumb and should not use data pins."

I short: there's no technical reason to have chip in the cable in order to prevent attack vector. All you need is signature of the end device (chip in the device, not in the cable) and computer (or phone, tablet, any host you connect your cable to) verify the signature of the connected device. With such you can easily spot malicious cable or tampered device.
There's no need to have any chip on the cable to prevent such attack vector. MFi is just Apple's money grab, it's not something actually useful for the security.
And that was point of my initial comment we started with.

I am Team MagSafe + remove the charging port altogether.
Because some people just like to watch the world burn.
Well, I believe I did not say that. And if I actually did I did not meant to and I'm sorry about that.
From what I remember I was meaning that charging itself does not use or need data pins. But of course you definitely can charge and use data pins at the same time - but in such case charging itself does not require nor use these data pins. That was my intended point.
its time for them to change the world. Utilize USB-C like on the iPad and allow people to connect to an external display and use their phone as the device for everything. With Thunderbolt wired speeds and wifi 6e plus whatever new chip they put in and an increase in storage this would be possible for sure. Perhaps why they haven't bothered updating the iMac past M1. The iMac is a dead platform in this scenario.
It’s really not complex. It’s probably the most basic thing. Both factors to calculate efficiency are very easy to measure
Totally in the same boat here. My iPhone 11 Pro Max bought when it came out is now at 85%. I never understood the need for fast charging overnight, as it will only wear the battery down faster. I do wish Apple would bring in the ability to limit the charge percentage, but that is never going to come I think.
I also charge my watches with the 5W adapter and even then the Ultra gets warm at the end. Sadly never got the “optimised charging“ feature working on the Ultra for some reason.
Edit: spelling.

Perhaps because it is a physically better construction? I love USB-C for the versatility, but a great design it is not.
Lightning feels sturdier than USB-C, there is no doubt about it. But it seems to be stuck with USB2 due to the lack of data pins in the current incarnation.
I'm not a huge fan of regulators interfering with IT-Standards. But in the case of USB-C I think it was (luckily) the right move.
Ironically most cheap USB-C charging cables are only capable of USB2 speeds as well. Faster USB connections require a cable with extra wires and a so called emarker-chip.
