Abstract
A method and apparatus reduce power consumption and mitigate declining battery life. In some embodiments, an initial full charge capacity, C(O), of a rechargeable battery is determined. A full charge capacity, C(t), of the rechargeable battery is determined at time t. An average power consumption profile is determined. A reduced power consumption is implemented based on the average power consumption profile and a factor C(t)/C(O). In other embodiments, functions that are not used in an average power consumption profile are deactivated. Other functions that occur in certain use cases of the average power consumption profile are activated and deactivated as needed.
