Why does the Xiaomi MIX Flip have the risk of heating when charging?

The phone uses 67W fast charging, and the charging rate is at a relatively high level. Charging with the screen off or powered off will be accompanied by heating, which is a normal phenomenon and within the safety standards. The phone will undergo strict professional investment before leaving the factory, so you can use it with confidence. It is recommended to expose the phone to the air when charging, reduce contact and avoid being wrapped with fabrics such as clothing, ensure a good heat dissipation environment, and effectively reduce the temperature.
When the phone is in normal use, the screen and processor work continuously, and the phone will generate some heat. At the same time, the phone uses 67W wired fast charging, and fast charging will be accompanied by heating. Using and charging at the same time will cause the heat to accumulate, and you will feel the phone is hot. It is recommended to reduce the frequency of using the phone while charging to relieve temperature rise.
Non-standard chargers will generate heat during charging due to incomplete adaptation. Please use the standard charger.
