Why does the Xiaomi 15T Pro get warm when charging with the screen off or when powered off?

The Xiaomi 15T Pro supports 90 W fast charging, one of the fastest charging standards in the industry. During high-power charging, a certain amount of heat is generated as the battery and charging circuit operate at higher efficiency levels. This temperature rise is normal and falls well within safety specifications.
All devices undergo rigorous safety and thermal inspections before leaving the factory to ensure safe and reliable operation.
To ensure an optimal experience, please refer to the following information:
  1. Ensure the phone is placed in a well-ventilated area and avoid covering it with clothing or other fabrics to improve heat dissipation.
  2. If the device feels uncomfortably warm, switch to standard charging mode for a more moderate temperature.
