Patent ID: 8106630

Claim:
A method for managing power in a battery powered portable electronic device having a battery, comprising: receiving a request to initiate a power intensive operation that consumes power at least in part from the battery; checking a battery level before initiating execution of the power intensive operation; initiating execution of the power intensive operation, performed by power consuming circuitry in the battery powered portable electronic device, when the battery level is greater than a first threshold level; checking the battery level during execution of the power intensive operation; canceling execution of the power intensive operation before completing the power intensive operation, when the battery level is not sufficient to successfully complete execution of the power intensive operation; after canceling execution of the power intensive operation and when the portable electronic device is coupled to an external power source, charging the battery from the external power source until the battery level is greater than a second threshold level, the second threshold level being higher than the first threshold level; and re-initiating from the beginning execution of the power intensive operation after charging the battery to greater than the second threshold level.
