Sorry, OPPO Find X3 does not currently support charging other phones via wireless charging. The wireless charging function usually requires that both devices support the corresponding wireless charging standard, and have the corresponding hardware and software support. At present, OPPO Find X3 series mobile phones only support wireless charging through devices such as wireless charging bases or charging banks, and do not support it as a wireless charging source to charge other mobile phones. If you need to wirelessly charge another phone, it is recommended to use a device that supports this feature.
oppofindx3 can use someone else's phone to charge itself wirelessly. Tap battery in Settings, turn on wireless reverse charging, and put the two phones back to back together
