In order to prevent damage and component failure from excess heat in a portable electronic device, thermal mitigation measures often are implemented by a thermal control module of the device. Temperature sensors, such as thermistors, provided with individual components of the device provide temperature information to a processor, which also receives information about the use of the device and its environment. Based on the temperature, usage, and environmental information, the processor determines whether thermal mitigation measures should be implemented to lower the temperature of one or more components to below a threshold and, if so, which mitigation measures to implement in order to do so with minimal impact on the experience of the user of the device.
