METHOD AND SYSTEM FOR PREDICTING THE POWER CONSUMPTION OF A MOBILE TERMINAL

摘要

A method of and device for predicting the power consumption of a battery-powered mobile terminal (15) used for carrying out a sequence of user activities. Each user activity involves an interaction with the terminal and each user activity causes one or more terminal activities involving power consumption of the terminal. The method comprises the steps of: - determining (4), for each user activity, which terminal activities it causes, - carrying out (6) a series of user activities (2a,...,2m), the terminal activities (Ia... In) of the series involving at least all terminal activities of the sequence, - measuring (6) the power consumption of the terminal while carrying out the series of user activities, - deriving (10) the power consumption of each terminal activity from the measured power consumption of the terminal, - adding (12), for each of the user activities of the sequence, the stored power consumption of the respective terminal activities caused by the particular user activity to obtain the power consumption of the respective user activity, and - adding (14) the respective power consumption of the user activities of the sequence to obtain the power consumption of the sequence.
