Anticipatory Power Management for Battery-Powered Electronic Device
First Claim
1. A method for managing power utilization by a multi-function electronic device powered by a battery, the method comprising:
- receiving a user request for activation of a supported function of the multi-function electronic device;
identifying an impending device usage, the identifying of the impending device usage being based at least in part on the user request to activate the supported function;
obtaining a power estimate for the multi-function electronic device to complete the impending device usage;
obtaining a battery characteristic associated with the battery;
determining, based on the battery characteristic, whether the battery has adequate capacity to satisfy the power estimate for the multi-function electronic device is to complete the impending device usage; and
reducing power consumption of the multi-function electronic device during at least the impending device usage by disabling one or more other supported functions of the multi-function electronic device when the determining determines that the battery has inadequate charge capacity to satisfy the power estimate for the multi-function electronic device to complete the impending device usage.
