You can tell if your Apple Watch is charging by the following indicators:

• When you place your Apple Watch on its magnetic charger, a charging symbol (a lightning bolt) appears on the watch face. If the lightning bolt is green, it means the watch is charging or fully charged

. If the lightning bolt is yellow, the watch is in Low Power Mode and charging up to 80%

• You should also hear a chime when charging begins, unless your watch is in Silent Mode

• If the watch is off or has a very low battery, placing it on the charger will cause the Apple logo and battery indicator to appear after a few seconds, indicating it is charging

• You can check the battery percentage and charging status by swiping up on the watch face to open Control Center, where the battery percentage appears in green if charging

• In the Settings app on the watch, under Battery, you can see the current charge level and a detailed charging graph

• If you see a red lightning bolt on the screen, it means the watch battery is too low to turn on and needs charging

In summary, the key signs your Apple Watch is charging are the green lightning bolt icon on the watch face or Control Center, the charging chime, and the appearance of the battery indicator when placed on the charger
