Dynamic feature-aware power management

摘要

This disclosure relates to reducing battery usage in handheld communication devices due to operation of variable managed features, such as a location determination feature and other features that consume variable amounts of time and power. The techniques of this disclosure include dynamically managing a power budget allocated to one or more variable managed features of the handheld communication device based on power consumption over time by the variable managed features. More specifically, the techniques include, for each variable managed feature, recalculating a frequency for performing power events based on an amount of remaining power after one or more power events. The techniques also include reallocating the power budget to the one or more variable managed features based on an amount of remaining power after one or more power events of the variable managed features, a pre-determined period of time, or reaching a threshold level of power consumption jitter.

主权项

1. A method of managing power consumption in a battery-powered device comprising:
determining an amount of power allocated to a variable managed feature supported by the device; performing one or more power events of the variable managed feature according to a distribution frequency that indicates when to perform the power events, wherein performing each of the power events consumes a variable amount of time and a variable amount of power; in response to performing the one or more power events, determining remaining battery life of the device based on the variable amount of time consumed by performing the one or more power events, and determining an amount of remaining power for the variable managed feature based on the variable amount of power consumed by performing the one or more power events; and recalculating the distribution frequency that indicates when to perform subsequent power events of the variable managed feature based on the remaining battery life of the device after performing the one or more power events, the amount of remaining power for the variable managed feature after performing the one or more power events, and average power consumption per power event.
