How to use wireless backcharging?

Wireless backcharging is a wireless charging technology that can be reversed by placing a wireless charging device on another charging device. Here are the general steps to use wireless backcharging:
1. Make sure your device supports wireless backcharging. For example, some phones support wireless backcharging, which can be used as a wireless charger.
2. Enable the reverse charging function of the wireless charging device. This can be found in the device's Settings menu, usually in charge management or battery Settings. 3. Place the device that needs to be charged on the wireless charging device, making sure there is no barrier between the two. 4. Ensure that the distance between the wireless charging device and the charged device does not exceed the maximum allowable range of wireless charging technology.
5. Wait for a period of time until the battery of the charged device is recharged.
It should be noted that wireless backcharging is generally slower and less efficient than wired charging. Therefore, it is suitable for temporary charging scenarios, such as charging other devices on the road or using the battery charger as a backup charger.


Step\/Method 1

Huawei mate40 is used as an example. It applies to HarmonyOS 2.0, iphone11, and ios16.0.

Step\/Method 3

Then put the Apple phone that needs to be charged on the back center of the Huawei phone to start wireless reverse charging.


The use of wireless backcharging is as follows:

< br >

1. Go to Settings → Battery → Enable the wireless reverse charging switch.

2. Turn on the device to be charged and place it in the center of the back of the phone. Do not place metal objects between the phone and the device to be charged.

3. If the device does not charge after 5 seconds, adjust the position and try again.

4. During the charging process, if the device to be charged is left for more than 2 minutes, the mobile phone will automatically turn off the wireless reverse charging switch.

Note that wireless reverse charging can only be activated when the phone is charged above 20% and in non-super power saving mode. In addition, the wireless reverse charging function is also effective for other devices that support the wireless charging protocol.


Wireless backcharging is a technology that allows energy to be transmitted between devices via radio waves. Before using wireless backcharging, first make sure your device supports the technology. In general, wireless reverse charging requires devices with newer wireless charging features and specific chips.

When using, it is necessary to place the device that supports wireless charging on the device that supports wireless backcharging, usually a charger or charging pad. A wireless connection is then established between the devices, and energy is transmitted to the device being charged via electromagnetic induction.

Wireless backcharging can provide a convenient way to charge without the need to plug and unplug the charging cable, but the charging efficiency may be lower than that of wired charging, so it is necessary to consider factors such as charging time and device location and alignment during use.


First, turn on the wireless reverse charging function of the mobile phone, and put the two mobile phones back to back together to automatically charge.
