A device can transmit a wireless communication signal to a linked device to instruct the linked device to power-off. In this manner, the user need only turn off one device manually which results in all linked devices being powered off. This process can be initiated by a user through a device directly linked with the device to be powered-off or through a device that is indirectly connected, through one or more wireless communication networks, with the device to be powered-off. This process can also be automatically initiated by a device when a set of predetermined conditions exist. Once instructed to do so, a device can initiate a predetermined power-off process which can involve terminating any ongoing functions and turning off various subsystems. In accordance with the present invention, a user can initiate a power-off of all the devices on a wireless communication network through a single device. ## Claims ### Claim 1 (canceled) ### Claim 2 An electronic device comprising: a radio frequency transceiver; and processor electronics configured to perform operations comprising: detecting a condition causing the electronic device to transition from a present power state to a lower-power state; determining at least a second device to transition to a lower-power mode in response to the electronic device transitioning to a lower-power state; transmitting a message, via the radio frequency transceiver, instructing the second device to transition to a lower-power mode; and transitioning to the lower-power state. ### Claim 3 (depends on 2) The electronic device of claim 2, wherein the lower-power mode comprises one of a sniff mode, a hold mode, or a park mode. ### Claim 4 (depends on 2) The electronic device of claim 2, wherein the lower-power state comprises a power-off state. ### Claim 5 (depends on 2) The electronic device of claim 2, wherein detecting the condition further comprises: detecting a battery threshold corresponding to a battery included in the electronic device. ### Claim 6 (depends on 2) The electronic device of claim 2, wherein detecting the condition further comprises: detecting a battery threshold corresponding to a battery included in the second device. ### Claim 7 (depends on 2) The electronic device of claim 2, wherein transmitting the message further comprises: transmitting the message in accordance with a Bluetooth communication protocol. ### Claim 8 (depends on 7) The electronic device of claim 7, wherein transmitting the message further comprises: transmitting the message over a direct communication link with the second device. ### Claim 9 (depends on 2) The electronic device of claim 2, further comprising: transmitting an other message, via the radio frequency transceiver, instructing a third device to transition to a lower-power mode. ### Claim 10 (depends on 9) The electronic device of claim 9, wherein transmitting the other message further comprises: transmitting the other message over an indirect direct communication link with the third device. ### Claim 11 (depends on 2) The electronic device of claim 2, wherein the message instructing the second device to transition to the lower-power mode further comprises an indication of a time at which the second device should transition to a higher-power mode. ### Claim 12 (depends on 2) The electronic device of claim 2, wherein the condition comprises an instruction to transition to an airplane mode. ### Claim 13 A method for changing a device power state, the method comprising: detecting, at a wireless communication device, a condition causing the wireless communication device to transition to a lower-power state; generating a message configured to cause a second wireless communication device to transition to a lower-power mode; transmitting the message to the second wireless communication device over a direct wireless communication link; and transitioning, by the wireless communication device, to the lower-power state. ### Claim 14 (depends on 13) The method of claim 13, wherein the condition comprises receiving a manual input received at an interface of the wireless communication device. ### Claim 15 (depends on 13) The method of claim 13, wherein the condition comprises receiving a voice command at an interface of the wireless communication device. ### Claim 16 (depends on 13) The method of claim 13, wherein transitioning to the lower-power state is performed automatically. ### Claim 17 (depends on 13) The method of claim 13, further comprising: determining that the second wireless communication device has been selected during configuration of a power-off process associated with the wireless communication device. ### Claim 18 (depends on 13) The method of claim 13, wherein generating the message further comprises: indicating a time at which the second wireless communication device should transition to a higher-power state. ### Claim 19 An wireless communication device comprising: a radio frequency transceiver; and a processor configured to perform operations comprising: receiving via the radio frequency transceiver, from an associated host device over a direct communication link, a message indicating that the host device is transitioning to a power-off mode and instructing the wireless communication device to transition from a present power mode to a lower-power mode; and initiating, based at least in part on the message, a transition to the lower-power mode. ### Claim 20 (depends on 19) The wireless communication device of claim 19, further comprising: outputting, from an interface component of the wireless communication device, at least one of an auditory alert or a visual alert in response to initiating the transition to the lower-power mode. ### Claim 21 (depends on 19) The wireless communication device of claim 19, wherein the lower-power mode comprises one of a sniff mode, a hold mode, or a park mode.
