Abstract:
1. A portable electronic device comprising: a rechargeable power source; a calendar application that stores a record of a future event, the event record having data associated therewith indicating a future usage of the electronic device; and a battery warning system that executes logic to generate a low battery charge warning, the logic including code to: obtain data related to a charge state of the rechargeable power source at a time t determine a predicted usage of the device for a period of time relative to time t determine a predicted power requirement to power the device during the predicted usage; determine a power requirement of the device associated with the event record, and correlate the power requirement associated with the event record with the power requirement determined from the predicted usage of the device relative to time t determine if the charge state of the power source is sufficient to supply the power, down to a threshold level, for the predicted power requirement; and generate a notice if the charge state is not sufficient for the predicted power requirement.
