Estimating remaining use time of mobile computing devices

摘要

Methods, systems, apparatus, and computer programs encoded on computer storage medium, for receiving a set of expected activities, each expected activity in the set of expected activities including an activity that is expected to be performed by a computing device, determining one or more time periods based on the set of expected activities, determining one or more expected rates of change of state of charge (SOC) of a battery of the mobile computing device by, for each time period of the one or more time periods, determining an expected rate of change of SOC based on a base rate of change of SOC and one or more expected activities associated with the time period, and determining an estimated remaining time based on the one or more expected rates of change of SOC, the remaining time corresponding to a time at which an expected SOC is less than a threshold SOC.

1. A computer-implemented method executed using one or more processors, the method comprising:
identifying a set of expected activities, each expected activity in the set of expected activities comprising an activity that is expected to be performed by a mobile computing device; determining, by the one or more processors, for each expected activity of the set of expect activities, an expected time when the expected activity is expected to be performed, the expected activities performed over one or more time periods; determining, by the one or more processors, one or more expected rates of change of a state of charge (SOC) of a battery of the mobile computing device by, for each time period of the one or more time periods, determining an expected rate of change of the SOC based on one or more expected rates of discharge associated with, respectively, one or more expected activities of the set of expected activities that are associated with the time period; determining, by the one or more processors, based on the one or more expected rates of change of the SOC a particular time at which an expected SOC is less than a threshold SOC; determining that the particular time at which the expected SOC is less than the threshold SOC occurs during an event time period of an expected event, and in response, providing a notification to the mobile computing device.
