Estimating remaining use time of mobile computing devices

A non-transitory computer-readable medium coupled to one or more processors having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations 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.

A mobile computing device, comprising:

• a display;
• one or more processors in communication with the display;
• and
• a computer-readable medium that is coupled to the one or more processors and that has instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations 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.
