Abstract: A wearable device includes multiple subsystems including a processor and a memory device, multiple temperature sensors coupled to sense temperatures of the multiple subsystems, and programming, including an application, stored on the memory device for execution by the processor to perform operations. The operations include receiving temperature information from the multiple temperature sensors corresponding to temperatures associated with the multiple subsystems, processing the temperature information to identify a first subsystem of the multiple subsystems, and providing a notification to the application executing on the processor to mitigate application performance in a manner to reduce heat generated by the first subsystem.
