Why does the Xiaomi 15T Pro overheat when using the small window feature?

The Xiaomi 15T Pro uses advanced multitasking technology to allow multiple Apps to run simultaneously through the small window feature. When several Apps are active at the same time, the CPU, GPU, and memory all process tasks concurrently, which increases system power consumption and leads to noticeable warmth on the device surface.
This is a normal thermal response during high-load scenarios and does not indicate a hardware fault. The device's thermal management system automatically adjusts performance and temperature to maintain safe operation.
All Xiaomi devices undergo rigorous factory inspections to ensure safety and reliability. The small window feature can be used safely under normal conditions, as the temperature will return to normal once the workload decreases.
