The Huawei Mate10 reverse charging logo is a circle with an arrow next to the lightning symbol in the top right corner of the phone battery. When using the reverse charging function, open the \"battery\" option in the phone Settings and select \"Reverse charging\" to turn it on. This function can turn the Mate10 into a mobile power supply that connects to another phone or device that supports wireless charging or a charging port type of USB-C to help charge other devices. Since this function requires the consumption of Mate10's own power, it is necessary to pay attention to the power situation when using.
Mate10 can not be charged, display reverse charge, can not be set in USB connection Settings, set to charge only mode, seconds jump back to reverse charge mode. When the charger is connected, restart the phone to charge it. The problem still occurs when the charger is pulled out and recharged.
