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.
