A method and system for reducing thermal load by monitoring temperatures within a portable computing device and, based on those temperatures, controlling a battery charge function are disclosed. The method includes monitoring a power management integrated circuit (PMIC) to determine if it is generating excess thermal energy that is contributory to an elevated temperature in a physically proximate application specific integrated circuit (ASIC). If so, and if the excess thermal energy is attributable to an ongoing battery recharge operation executed by the PMIC, a thermal policy manager module may execute a thermal mitigation technique algorithm to override the PMIC battery recharge function. One exemplary thermal mitigation technique may include a reduction of current sent to the battery, thus slowing the charge cycle and reducing the generation of excess thermal energy. |
