Abstract
A method and apparatus are disclosed for power management of an electronic device. The present invention reduces power consumption of an electronic device that communicates over a network by selecting a transmission mode with reduced power consumption as the battery level gets lower. A disclosed power management process monitors the battery level of an electronic device and selects a transmission mode (e.g., a transmission rate) with a lower power consumption when the battery power level reaches one or more predefined threshold levels.
Claims20
A method for power management in an electronic device that communicates over a network, said method comprising the steps of:
- monitoring a battery level of said electronic device;
- evaluating a power consumption of said electronic device in one or more transmission modes;
- establishing one or more threshold levels based on said power consumption information;
- and
- selecting a rate of a substantially continuous transmission mode based on a comparison of said battery level to said one or more threshold levels.
An electronic device, comprising:
- one or more batteries;
- one or more ports for network communication;
- a memory;
- and
- at least one processor, coupled to the memory, operative to:
- monitor a battery level of said electronic device;
- evaluate a power consumption of said electronic device in one or more transmission modes;
- establish one or more threshold levels based on said power consumption information;
- and
- select a rate of a substantially continuous transmission mode based on a comparison of said battery level to said one or more threshold levels.
A power management driver for an electronic device that communicates over a network, said driver implementing the steps of:
- monitoring a battery level of said electronic device;
- evaluating a power consumption of said electronic device in one or more transmission modes;
- establishing one or more threshold levels based on said power consumption information;
- and
- selecting a rate of a substantially continuous transmission mode based on a comparison of said battery level to said one or more threshold levels.
