First Claim
Patent Images
1. A method for managing power utilization by an electronic device powered by a battery, the method comprising:
- receiving a user selection indicating an imminent usage for the electronic device;
estimating a future power requirement for the electronic device based on the imminent usage;
obtaining a battery characteristic associated with the battery;
determining, based on the battery characteristic, whether the battery has adequate capacity to satisfy the estimated future power requirement for the electronic device; and
reducing power consumption of the electronic device when the determining determines that the battery has inadequate capacity to satisfy the future power requirement; and
presenting a notification regarding charging the battery when the determining determines that the battery has inadequate capacity to satisfy the future power requirement, the notification including a recommended charging duration, the recommended charging duration being based on the estimated future power requirement.
