Why does the POCO X7 Pro heat up seriously when charging at high speed while the screen is off?

We apologize for the inconvenience caused to you. The POCO X7 Pro is equipped with 90W charging technology, and the charging speed is at a relatively high level. After turning on the Speed up charging mode, it will be accompanied by a certain amount of heating, which is normal. The temperature rise is within the safety standard and can be used with confidence. If you feel that the current heating experience is poor, you can try to turn off the Speed up charging in [Settings] >> [Battery] >> [Charging options] to improve the charging temperature rise experience. In addition, it is recommended that you place the phone in a relatively open area when charging, reduce contact and wrapping with fabrics such as clothes and quilts, ensure a good heat dissipation environment, and effectively reduce the temperature.
