How to set the preheating function of the Xiaomi Smart Air Fryer 5.5L?

You can set the preheat temperature to 200°C and run with an empty basket for 3-5 minutes. Also, you can open the Mi Home app to enable the preheating function.
Note:
The Xiaomi Smart Air Fryer 5.5L can heat fried food. However, it is not recommended to heat food with soup. It will produce high-speed hot air when the air fryer is heated, which can cause the soup to splash out.
