Method and apparatus for detecting abnormal power consumption of a battery in mobile devices

摘要

A method for detecting abnormal power consumption of respective batteries in mobile devices includes defining one or more operational states affecting power consumption of the batteries; collecting time-series data on an amount of the power consumption and use time of each battery in each of the operational states; calculating a power consumption rate, usage patterns, and an actual use time of the individual batteries based on the time-series data; estimating an amount of an available time remaining on the individual batteries based on average power consumption rate of all of the batteries; and comparing the estimated available time with the actual use time of the individual batteries to judge whether a power of the individual batteries is being consumed abnormally.
