Abstract
A portable electronic device that can receive power from an internal power source (such as a battery) and/or a second portable electronic device is described. In order to coordinate the power availability in these portable electronic devices, a power-management mechanism in the portable electronic device (which may be implemented in hardware and/or software) may determine a power state of an internal power source in the second portable electronic device, and may accordingly adjust a power consumption by circuits in the portable electronic device and/or the power received from the second portable electronic device. In this way, the power-management mechanism may approximately synchronize the power consumption in the portable electronic devices and/or the power states of the internal power sources in the portable electronic devices. This approximate synchronization may facilitate concurrent operation of the portable electronic devices.
