Predicting battery power usage

A computing system comprising:

• a processor;
• a memory communicatively coupled to said processor;
• and
• a battery to power said computing system;
• in which said processor is configured to:
• collect information relating to battery power consumption due to tasks performed by said computing system;
• and
• notify a user in response to a determination that tasks associated with an upcoming event stored in a calendar application of said computing system are projected to exhaust said battery, and recommend that a number of specific applications or hardware components not needed for said upcoming event be shut down to conserve battery power during said upcoming event.

A computer program product for predicting battery power usage, said computer program product comprising:

• a non-transitory computer readable storage medium having computer readable code embodied therewith, said computer readable program code comprising:
• computer readable program code configured to collect information relating to battery power consumption due to tasks performed by a physical computing system running said computer program product;
• and
• computer readable program code configured to notify a user in response to a determination that tasks associated with an upcoming event stored in a calendar application of said physical computing system are projected to exhaust said battery,
• wherein an entry for said upcoming event in said calendar application comprises an indication, entered by a user creating said entry, of the tasks associated with said upcoming event, said computer readable program code using said indication entered by said user to determine whether the tasks associated with said upcoming event are projected to exhaust said battery.

A method for predicting battery power usage, the method comprising:

• with a physical computing device powered by a battery, collecting information relating to battery power consumption of tasks performed by said physical computing system during events stored in a calendar application of said physical computing system;
• with said physical computing system, determining which of said tasks are to be used in an upcoming event in said calendar application;
• with said physical computing system, at a predetermined time before said upcoming event, determining whether said tasks associated with said upcoming event exhaust said battery during said upcoming event based on a level of battery power in said battery at said predetermined time;
• and
• with said physical computing system, notifying a user if said determination indicates that said tasks associated with said upcoming event are projected to exhaust said battery during said upcoming event.

A computing system comprising:

• a processor;
• a memory communicatively coupled to said processor;
• and
• a battery to power said computing system;
• in which said processor is configured to:
• collect information relating to battery power consumption of tasks performed by said computing system during events stored in a calendar application on said computing system;
• determine which of said tasks are used for an upcoming event in said calendar application;
• determine whether said tasks will exhaust said battery during said upcoming event considering independently powered peripherals available at a location of said upcoming event that can be used to reduce demands of said computing system on said battery to perform said tasks during said upcoming event;
• and
• notify a user if said determination indicates that said tasks associated with said upcoming event are projected to exhaust said battery.
