In order to use the OPPO Find N3 Flip for wireless charging, you need to enable wireless charging in your phone. Go to the Settings menu and select \"Battery,\" then swipe the screen and select \"Wireless Charging.\" Make sure the wireless charging switch is set to on.
Next, place your phone on a compatible wireless charger and make sure the distance between the two is close enough.
Once your phone starts charging, you will see a charging indicator. Note that wireless charging may be slower than wired charging, but it's more convenient because you don't need to use a charging cable.
