I am having a problem charging my apple watch 7. It connects but will not charge. I restart it and it will work and a few days later it does the same thing.

Are you using the correct USB-C Power Adapter recommended by Apple? I know one wasn’t provided in the box. If you are and you feel it’s faulty get in touch with Apple to set up an appointment at a Genius Bar. Get Support

About fast charge on Apple Watch Series 7 - Apple Support

You need one of these power adapters:

• Apple 18W, 20W, 29W, 30W, 61W, 87W, or 96W USB-C Power Adapter
• A comparable third-party USB-C power adapter that supports USB Power Delivery (USB-PD) of 5W or greater

If you're not sure which Apple Power Adapter you have, check the wattage on the top or bottom of the adapter:

I've also got a problem with my new Apple Watch 7 not charging. It does it OK for a day or two then just doesn't charge. I have to force restart (crown and side button) then it's OK again, which suggests a software problem rather than hardware (I hope). Doesn't matter if it's my old Apple Watch 1 charger or the USB-C fast charge that came with the watch, it does the same thing.

Apple, please sort it. Never had this ever with the 1.

This is a user to user only forum. Asking Apple to sort anything here is worthless. You need to contact Apple directly. Either call them, use the Get Support button at the top of this page or go to your Apple Store Genius Bar for help.

I’m having the same issue in my series 7. It happened twice so far. I’m using the cable that came with it and the brick that I purchased at the apple store. Never had this issue with my previous watches.
