Automatic Power-Off of Wireless Communication Device from Linked Device

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.

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.

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.
