Reverse charging can be used to charge the equipment in an emergency.
Conditions for reverse charging:
1. The output device needs to support OTG and reverse charging functions;
2. Prepare a reverse charging data cable.
Reverse charging operation method:
1. Enable OTG connection on the device that provides power:
realme UI 7.0 & 6.0: Settings > Accessibility & convenience > Turn on OTG connection.
realme UI 5.0 & 4.0 & 3.0 & 2.0 & 1.0: Settings > Additional/System settings > Turn on OTG connection.
realme UI R & S & T & Go & U Edition: Settings > System > OTG connection.
2. Connect the two devices together through the reverse charging data cable to charge.
Note:
1. The device being charged has no limitation on the type of charging interface, but the OTG cannot be turned on, otherwise, the charging direction may be uncertain.
2. The impedance of the connecting line is too large (more than 250 milliohms), which may cause it to fail to charge.
