Why does the Xiaomi 14T heat up when using floating window shortcuts?

The function of floating window shortcuts allow you to access APPs quickly without switching between full screens, making it easier to perform tasks simultaneously. You can launch frequently used APPs or functions directly from any screen, enhancing efficiency. Floating windows can overlay on other APPs, letting you continue viewing content while using other features.
Flowing window shortcuts involves running several APPs in the background, which requires more CPU and RAM resources, leading to continuous processing and heat production. If the floating windows are for resource-intensive applications (like games or video streaming), the heat can increase significantly.
