Why does the Redmi Note 14 Pro+ 5G get hot at times during the first week after a system update or when switching to a new device?

Thank you for supporting Xiaomi products. HyperOS is a highly customized system with many features. When setting up a new phone, it undergoes processes like data recovery and system updates, which can cause some heating. Additionally, all installed APPs are compiled after being downloaded to improve performance, and cloud data is synchronized, leading to higher background power consumption. Once the phone completes all its initialization processes, the temperature will stabilize.
It is recommended to monitor usage for a while. After switching to a new device, make sure to update the software. Old APPs could not be fully compatible with the current Android base. Please update or reinstall APPs for better compatibility.
