Thank you for your support of Xiaomi products. When performing a device switch, the phone needs to process a large amount of data at high speed, while also installing, compiling, and restoring data for APPs. Therefore, the CPU system will be under full load, resulting in higher system power consumption and causing the phone to heat up to some extent during the switching process, which is normal. The temperature during the device switch complies with safety standards, and the temperature will gradually return to normal after the switching process is complete.
Additionally, during software updates/downloads, to complete the software download and installation faster, the phone's network and load will increase, leading to increased power consumption and heat generation, which is a normal phenomenon.
The Xiaomi HyperOS is highly customized and comes with many features. When you have a new phone, it goes through processes such as data recovery and system updates, which will cause some heating. Moreover, to ensure smooth usage of all installed APPs, they will undergo compilation after download, and cloud data will be synchronized, leading to higher background power consumption. Once the phone completes all initialization configurations, the temperature will return to normal. We recommend observing for some time during use.
