摘要
Various embodiments of methods and systems for thermal energy management in a portable computing device ("PCD") based on power level calculations are disclosed. One exemplary method includes tracking instantaneous operating temperatures and active power supply levels for one or more components. By estimating or measuring the ambient temperature, the instantaneous operating temperature values and the active power supply level values can be used to calculate the instantaneous thermal resistance value. In the case where thermal energy generation must be managed, the target operating temperature may be used in conjunction with the ambient temperature and the instantaneous thermal resistance value to solve for the optimum power supply level. The active power supply level may then be adjusted based on the calculated optimum power supply level.
