Find out if your Apple Watch is charging

When you connect your Apple Watch to its charging cable and power, a lightning bolt  should appear on the screen.

If your Apple Watch with watchOS 9 or later is in Low Power Mode, the icons, time, and day shown below all appear in yellow.

If your watch requires charging, a red lightning bolt  appears on the screen. (You might need to press the side button to make the watch face appear.) When your watch is charging, the red lightning bolt  changes to a red lightning bolt inside a ring. If your screen is blank or the charging cable icon appears on the screen, charge your watch for up to 30 minutes. 

If you need further assistance, please contact Apple Support, as they'll best able to help. You may be able to reach them here: Get Support

Thanks!

Took the watch to apple service centre in Delhi. the watch is connected to phone all sounds are made even siri works but display is gone. no falling no damage . it just went away. they said it will cost 60,000 Rupees that is 750 USD and i will get a similar series (7) refurbished watch.

I think it’s time to shift from apple ecology to windows.

iphone has no cutting edge anymore and the service not only poor the products are risky. spent nearly a thousand dollar to buy it with meg strap and it’s gone just like that. Seriously thinking of changing watch to a mechanical automatic one and while at it iphone to an android one . will still keep macbook though until i relearn windows environment.

this really hurts
