If your Apple Watch is not charging or turning on
Apple Watch is not charging or turning on, there are several troubleshooting steps you can try to resolve the issue. Here’s what you can do:
Check the charger and cable:
Ensure that you are using the official Apple Watch charger and cable. Make sure they are securely connected to both the charger and a power source. Try using a different outlet or USB port to eliminate the possibility of a power issue.
Clean the charging contacts:
Inspect the charging contacts on the back of your Apple Watch and the charger for any debris, dirt, or residue. Gently wipe them with a clean, lint-free cloth. Ensure that the charging contacts are not damaged or bent.
Restart your Apple Watch:
Press and hold the side button (not the Digital Crown) until the power off slider appears. Slide it to turn off the watch. After a few seconds, press and hold the side button again until the Apple logo appears, indicating that your watch is restarting.
Force restart your Apple Watch:
If a regular restart doesn’t work, try a force restart. Press and hold both the side button and the Digital Crown simultaneously for at least 10 seconds until the Apple logo appears. Release the buttons and allow your watch to restart.
Verify the battery level:
Connect your Apple Watch to the charger and wait for a few minutes. If the battery is completely drained, it may take some time for the charging icon to appear. If it doesn’t show any signs of charging after 30 minutes, proceed to the next step.
If none of the above steps resolve the issue and your Apple Watch still won’t charge or turn on, it’s best to contact Apple Support or visit an authorized service provider for further assistance. They can provide additional troubleshooting steps or assess if there is a hardware issue that needs repair.
Remember to ensure that your Apple Watch and charger are not physically damaged and that you have the latest software updates installed on your iPhone and Apple Watch.
How to find out if your Apple Watch is charging or not
When you connect your Apple Watch to its charging cable and a power source, a lightning bolt 
should appear on the screen.
If your Apple Watch with watchOS 9 is in Low Power Mode, the icons, time, and day displayed below will all appear in yellow.
If your watch requires charging, a red lightning bolt 
will appear on the screen. (You may need to press the side button to make the watch face appear.) When your watch is charging, the red lightning bolt 
will change to a green or yellow lightning bolt 
. If your screen is blank or the charging cable icon and a red lightning bolt 
appear on the screen, charge your watch for up to 30 minutes. https://support.apple.com/en-au/HT204640
