Why does the Xiaomi 14 heat up when charging?

When the phone is used normally, the screen and processor work continuously, leading to some heat generation in the device itself.
Additionally, the Xiaomi 14 utilizes 90W fast charging technology, which boasts a relatively high charging rate in the industry. Fast charging inevitably generates some heat, which is a normal phenomenon and falls within safety standards. Before leaving the factory, all phones undergo strict professional inspection, so you can use them with confidence.
We recommend disabling the speed up charging feature or ensuring the phone is exposed to air during charging, minimizing contact with clothing or other fabrics to maintain good heat dissipation conditions, which can effectively reduce the temperature.
