Abstract
Certain aspects of the present disclosure relate to a technique for touch temperature management of a wireless communications device based on power dissipated over time, and possibly internal temperature readings. For example, the information about power dissipated over time can be utilized along with monitored internal temperatures of a device's internal circuitry to reduce transmit power and/or data rates as required in order to keep a surface temperature of the wireless device below a specified limit. A knowledge of how the device's touch temperature varies with the dissipated power and a knowledge of the power dissipation history can be utilized to determine when to reduce the transmit power in order to avoid overheating (e.g., exceeding the touch temperature limit).
