Why does the Xiaomi 17 Ultra get so hot when making a video call and using another App at the same time?

Question

Accepted Answer

If the Xiaomi 17 Ultra becomes warm when making a video call while using another App, please refer to the following explanation:
1. Running a video call requires continuous camera operation, video encoding, network transmission, and display processing.
2. Using another App simultaneously increases CPU and GPU workload, resulting in higher overall system resource usage.
3. The combined workload significantly raises power consumption compared with using a single application.
4. Increased power consumption can lead to a noticeable temperature rise during multitasking scenarios.
5. The Xiaomi 17 Ultra undergoes strict system stability and thermal performance testing before leaving the factory. This temperature increase during multitasking is a normal operating behavior.
