More Information
Summary: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 (112,114,116) of each battery in each of the operational states; calculating a power consumption rate, usage patterns, and an actual use time (140) of the individual batteries based on the time-series data; estimating an amount of an available time remaining (150) on the individual batteries based on average power consumption rate (132) of all of the batteries; and comparing (176) the estimated available time (150) with the actual use time (140) of the individual batteries to judge (160) whether a power of the individual batteries is being consumed abnormally.
