My watch will not charge. I have made sure the back of the watch and charging magnet are clean. I am using the charging magnet that came with the watch. I have tried to reset it too by pressing the crown and button on the side for 10 seconds

Hi

I am facing the same issue. I tried contacting Apple support in phone and also by visiting my nearest Apple store genius support. They do not offer any diagnosis for free but will be charged 299$ + Shipping to tell me what’s the problem. 

This issue started for me when my watch ran out of charge and prompted me to “Turn On” Power reserve. After getting access to my charger (apple watch magnetic charger cable) I had left the watch and waited for it to charge. I tried  to power it back on after a few hours and also after a few days, it never came back on and was struck in power reserve screen. 

After two weeks the power reserve screen  got replaced with the screen that prompts you to charge(Red lightning bolt ⚡️ ). It never charged after that day I had put my watch to power reserve. 

So, Apple did release a document on their support site where it was describing the same problem I just mentioned above and it looks similar to the issue you and me are experiencing. When I contacted Apple support they rejected to take the watch under free repair or for a diagnosis citing that my watch was running an updated OS version and it does not qualify for any of the repair mentioned in this document. 

Please go through this document:

If you find out your watch is running 7.2 or 7.3 contact support and mention this article. 

What surprises me is the apple store genius support  didn’t mention this until I showed them. 

It is very unfortunate and weird that my watch is not charging and they don’t even offer any free diagnosis to identify the issue. I own quite a few apple products over the last 5 years and this is first time a product of Apple just died on me all of a sudden and no support for it without an exorbitant cost attached with it. 

Good Luck 🤞🏽

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

They offered me free diagnosis and then shipped me back a replacement that was also broken and won’t charge or pair. I’ve spent hours on the phone and have been weeks without my watch- it seems they are avoiding replacing watches with known issues and not addressing a hardware failure on their part.

Can you try a different charger happened me before needed new charger
