Let's talk about the charging cable version of the Apple Watch 7-8-Ultra.
Write down what version you have. You can see it: About this Mac - System report... - USB
My AW7 cable has version 19.10 and it doesn't charge the watch with fast charging. I got another cable from AW8 version 21.30 and it charged like it should, very fast.
Share your observations.

Thank you for your reply. Can you tell me when you purchased the watch? I want to understand the connection of the versions of the chargers. And I hope that the cable gets a software update

I just bought it used a week ago from eBay, but it still has limited warranty on it till May, so I think the watch is less than a year old.

When you view information on mac does it appear like this? I see that it lacks the Sleep current section compared to my old series 5 charger. I'm really confused because I bought this charger again.
