•
as metal objects and magnets, are placed between the device and the wireless

charger and components that support the feature.
You can check the connection status of the charger by opening Settings and tapping
Battery and device care → Battery.
If fast charging does not work, open Settings, tap Battery and device care
•
→ Battery → More battery settings, and then check if the feature you want
is turned on. Also, check if the USB cable and the USB power adapter are

turn off automatically at the preset time using Routines. When the fast wireless
charging feature turns off, the charger's fan noise and the indicator light will be
reduced.
