Battery management assistant

A method of coordinating power usage in a plurality of devices, comprising:

• determining, with one or more processors, a present battery level each of the plurality of devices;
• determining, with one or more processors, a present usage rate for each of the plurality of devices;
• accessing, with one or more processors, a scheduled event;
• calculating, with one or more processors, a battery outlook for the scheduled event for each of the plurality of devices;
• calculating, with one or more processors, a future battery level, using at least the present battery level, the present usage rate, and the battery outlook for the scheduled event for each of the plurality of devices;
• comparing, with one or more processors, the future battery level of one or more of the plurality of devices with a threshold level to determine a power expectancy;
• determining, based on the comparison, that the future battery level satisfies the threshold and, in response, causing a message to be presented to the user, wherein the message is one or more of:
• a recommendation to charge the device, a recommendation to alter the operation of the device, a recommendation to turn off the device, or a recommendation to use alternate sources of power;
• comparing a future use of the device with the message to create a determination of compliance with the message;
• storing, with one or more processors, the determination of compliance with the message;
• and
• determining whether to present a future message based on the stored determination of compliance or altering, based on the power expectancy, with one or more processors, at least one usage state of one or more of the plurality of devices;
• and
• wherein altering the usage state comprises one or more of powering one or more of the plurality of devices off, closing an application, turning off an antenna, dimming a screen, or entering a sleep mode.

A non-transitory computer-readable medium having computer-executable instructions stored thereon which, when executed by one or more processors effectuate operations comprising:

• determining, with one or more processors, a present battery level of a first computing device and a second computing device, the level being a value indicative of an amount of energy stored by the battery;
• determining, with one or more processors, a present usage rate of battery energy by the first computing device;
• accessing, with one or more processors, an event record in memory describing a scheduled event in which a user of the first computing device is scheduled to participate in the future;
• inferring, with one or more processors, a battery outlook corresponding to the scheduled event, the battery outlook being an estimated amount of energy consumption attributable to the scheduled event;
• predicting, with one or more processors, a future battery level of the first computing device based on at least the present battery level of the first computing device, the present usage rate of the first computing device, and the battery outlook corresponding to the scheduled event to improve battery usage or battery management of the computing device;
• comparing a future battery level to a threshold amount;
• determining, based on the comparison, that the future battery level satisfies the threshold and, in response, causing a message to be presented to the user, wherein the message is one or more of:
• a recommendation to charge the device, a recommendation to alter the operation of the device, a recommendation to turn off the device, or a recommendation to use alternate sources of power;
• comparing a future use of the device with the message to create a determination of compliance with the message;
• storing, with one or more processors, the determination of compliance with the message;
• and
• determining whether to present a future message based on the stored determination of compliance.
