I wonder how much energy is lost when charging wirelessly.

They don't support wireless charging from phone to airpods. That would be great, and is available on some android devices. This was referring to being able to charge your airpods or watch by plugging them into your phone with a cable.

Oh, that's silly. If I had a charge cable with me I'd also have my computer or iPad, which I can use to charge.

You might... but most people won't? A cable slips into a purse easily for a night out or something.

There is a zero percent chance that I would ever want to boost my AirPods case, (which I charge every few days) while draining my iPhone (which I charge daily). If I had an Apple Watch, I would not bring the puck charger with me anywhere. I don't think that "most people" would; a subset of iPhone users have purses, and a subset of iPhone users have Apple Watches. I'm pretty sure the intersection of those two subsets is not even close to the majority of iPhone users.

The "charge iot thing wirelessly from phone" feature on my Samsung phones for the past few generations isn't used every day but it is useful every so often. E.g. go on a trip but forget smartwatch charger. No problem the phone can do it in a pinch. Or: family member gets their phone wet causing it to not charge wired until it dries. No problem my phone can charge their phone wirelessly.

I think they're referring to plugging a usb cable into the phone to charge a device.

It might work without plugging in the iPhone, but I imagine most times it would be plugged, overnight or whatever.

This is honestly a pretty great feature, and actually makes me more likely to buy an Apple Watch. I don't want to have to bring another charge cable with me, and now I wouldn't have to. I wonder what the charge speed is though — I wouldn't want to have to charge it overnight.

EDIT: Thanks for clarifying, it took me a while to understand based on what they had said and what Ars reported. I can see that it's just the same as how you can plug any peripheral into an iPad and charge off its battery. Now you can do the same with iPhone...big deal.

No, I think you connect a cable from the iPhone's charge port to the AirPod's charge port.

Apple's page says this under the USB-C section:

>The new USB-C connector lets you charge your Mac or iPad with the same cable you use to charge iPhone 15. You can even use iPhone 15 to charge Apple Watch or AirPods. Bye-bye, cable clutter.

With a footnote that leads to this:

> The included USB‑C Charge Cable is compatible with AirPods Pro (2nd generation) with MagSafe Charging Case (USB‑C).

Not to mention the Apple Watch takes a special rounded magnetic charger. I don't think it would interface correctly otherwise.
