1. You can enable the anti-charge function by setting.
2. Because the oppo Reno4 supports anti-charging function, you can realize the anti-charging function by connecting the phone to another device that supports wireless charging, such as wireless headphones or smart watches.
3. The anti-charging function can be set by entering the phone Settings - battery - anti-charging, after opening, you can connect the oppo Reno4 to other devices for anti-charging.
It should be noted that the anti-charge function can only be used when the oppo Reno4 battery is low, and it is also necessary to ensure that the connected device supports wireless charging.
The answer is as follows: The OPPO Reno4 does not support the anti-charge function, so the function cannot be enabled. Anti-charging refers to using the phone's battery to charge other devices, and the OPPO Reno4 doesn't have this feature.
