Managing energy usage in mobile devices
摘要
說明書
In certain example embodiments, the identifying is carried out by the processor on the basis of an assigned priority of the plurality of systems or processes and selecting a lowest priority system or process that can be converted to a lower power consumption state as the identified system or process. In certain example embodiments, the determining is carried out by the processor on the basis of a battery temperature, battery terminal voltage, and battery current draw as measured by the battery monitor circuit. In certain example embodiments, the processor calculates the battery power factor by: assigning a value to each of the current state of the battery temperature as T; assigning a value to the terminal voltage as V; assigning a value to the current draw as I; and computing the battery power factor as the sum of T, V and I. In certain example embodiments, the identified system or process is a heater element, and where the processor reduces the power consumption by either deactivating the heater element or causing the heater element to operate at less than 100% heat generation.
In certain example embodiments, the processor is further programmed to: repeat the determining, calculating, and comparing; identify a further system or process within the mobile device whose power consumption can be reduced; and further reduce the power consumption by altering or disabling the further system or process. In certain example embodiments, identifying a system or process and identifying a further system or process are carried out by the processor on the basis of an assigned priority of a plurality of systems or processes and selecting a lowest priority system or process that can be converted to a lower power consumption state as the identified system or process and further identified system or process.
