    摘要： A power management method with a portable electronic device (100) includes identifying, with a controller (202) of the portable electronic device, a power consumption event in the portable electronic device, the power consumption event having a power consumption requirement. The method further includes selecting (818), in response to the identifying, one of a collection of energy storage devices (304, 306, 308, 320) in an energy storage device farm (218) for the portable electronic device, the selecting being based at least on the power consumption requirement of the power consumption event and on one or more characteristics of the one of the plurality of energy storage devices. The portable electronic device executes the power consumption event using energy stored in the selected one of the plurality of energy storage devices. The portable electronic device (100) may be a mobile phone or other wireless communication device.

    摘要： In accordance with the teachings described herein, a method and apparatus for handling a charging state in a mobile electronic device is provided. A universal serial bus (USB) interface may be used for connecting the mobile device to a USB host. A processing device may be used to execute programs and to control operation of the mobile device. The processing device may be operable to receive an enumeration acknowledgement signal from the USB host via the USB interface and generate an enable signal upon receiving the enumeration acknowledgement signal. A rechargeable battery may be used to power the processing device. A battery charger may be used to receive a USB bus voltage from the USB interface and use the USB bus voltage to power the processing device and to charge the rechargeable battery. The battery charger may be further operable to receive a charge enable signal that enables and disables the battery charger from powering the processing device and charging the rechargeable battery. A timing circuitry may be used to detect the USB bus voltage and to measure the passage of a pre-determined amount of time upon detecting the USB bus voltage. A battery charger enabling circuitry may be used to generate the charge enable signal to control the battery charger, the battery charger enabling the battery charger if the timer has measured the passage of the pre-determined amount of time or the enable signal is received from the processing device.
