First of all, we need to ensure that the power of the one plus phone is sufficient, and then click the battery option in the one plus phone Settings, and then open the mobile phone reverse wireless charging function in the battery option, and use the back of the one plus phone as close as possible to the middle of the back of other phones, so that the one plus phone will start to wireless charge other phones.
No, the phone hardware does not support wireless charging.
