Use Wireless Reverse Charging Wireless reverse charging is supported by devices that support the Wireless Charging Standard, such as phones, tablets, watches, and bands. Before using wireless reverse charging, ensure that the battery level of your device is higher than 20%. 1 Go to Settings > Battery, and enable Wireless Reverse Charging. 2 Power on the device to be charged, and place it on the centre of the back of your device. Do not place any metal objects between your device and the device to be charged. 3 If the device does not start charging within 5 seconds, adjust its position and try again. 4 If the device to be charged is removed from the device for more than 2 minutes during charging, Wireless Reverse Charging will automatically be disabled.

You can use your device to charge other devices using an OTG cable. 1 Connect your device with the device to be charged using an OTG cable. 2 Swipe down from the status bar to open the notification panel, touch Touch for more options, and then select Reverse charge. 3 Follow the onscreen instructions on the device to be charged to start charging. 29
