Hello kreg56, 


Apple Support Communities is a great place for help with fast charge on your Apple Watch Series 7. We see you came from the article About fast charge on Apple Watch Series 7, and we’re glad you had the chance to review that article. 


You mentioned that it works sometimes. Are you noticing issues where the Apple Watch isn’t charging at all, or that it doesn’t always fast charge? If the issue is with the Apple Watch not charging at all, try the steps outlined in the following article. 


If your Apple Watch won’t charge or it won’t turn on


If you’re having issues where it’s charging, but not always fast charging. Can you let us know in more detail about the experience you’re facing? 


We look forward to your response!

I was having odd issues where the usb-c fast charger that came with the Apple Watch series 7 wouldn't charge at all even though the lightning bolt would show once the watch was placed on the usb-c fast charger, then the watch screen would go black (I have "always on" set to on and usually when the watch is on charge the watch screen would light up periodically with the time but not this time) and a spinning circle, like it was rebooting, would appear and the watch screen would stay black until I forced restarted the watch but the watch didn't charge at all. I called customer service and the female agent was very helpful and we decided to replace the cable which is still in progress so I will probably cancel it now because the watch OS 8.1.1 update, that lobsterghost1 was kind enough to alert me to, has done the trick. Thanks you for your response.
