Abstract: A method and system for managing electrical current within a portable computing device (“PCD”) includes assigning a priority to two or more communications supported by the PCD. A present level of a power supply for the PCD may be monitored by a communications power (“CP”) manager module. Next, the CP manager module may determine if the two or more communications may be transmitted at the present level of the power supply. If the two or more communications cannot be transmitted at the present level of the power supply, then the CP manager module may determine if a timing of at least one of the communications may be adjusted. The CP manager module may also determine a theoretical power level adjustment for at least one of the communications. The two or more communications may be transmitted with any calculated timing off sets and power level adjustments.

A power supply supplies power to a CPU and a RAM in a standby state, supplies power to the RAM without supplying power to the CPU in a second waiting state caused by turning off the power switch, and supplies power to the RAM without supplying power to the CPU in the power saving state caused without having the power switch turned off when a shift-to-power saving state requirement defined in advance is satisfied. A power supply controller causes the apparatus to shift from the second waiting state to the standby state using a standby memory image. The CPU writes the standby memory image in the RAM for storage in the power saving state.

Abstract: Various embodiments of methods and systems for adaptive thermal management techniques implemented in a portable computing device (“PCD”) are disclosed. Notably, in many PCDs, temperature thresholds associated with various components in the PCD such as, but not limited to, die junction temperatures, package on package (“PoP”) memory temperatures and the “touch temperature” of the external surfaces of the device itself limits the extent to which the performance capabilities of the PCD can be exploited. It is an advantage of the various embodiments of methods and systems for adaptive thermal management that, when a temperature threshold is violated, the performance of the PCD is sacrificed only as much and for as long as necessary to clear the violation before authorizing the thermally aggressive processing component(s) to return to a maximum operating power.
