Patent ID: 8761844

Claim:
A mobile device configured to control power consumption, the mobile device comprising: a speaker to deliver a sound from the mobile device; a microphone to receive at least a voice communication at the mobile device; a display screen to present data to a user of the mobile device; a power supply to receive power from a power source; a transmitter to send transmitted data; a receiver to receive incoming data, wherein the mobile device includes operational modes comprising an idle mode, a calling mode, a called mode, an in-call mode, a sleep mode that is transitioned from the idle mode, a sleep mode that is transitioned from the calling mode or the called mode, and a sleep mode that is transitioned from the in-call mode; and a controller configured to receive an input from a user or detect an elapse of a predetermined time interval and to responsively perform operations including: when the mobile device is operative in the idle mode, transition the mobile device from the idle mode to the sleep mode that is transitioned from the idle mode in response to receiving the input or detecting the elapse of the predetermined time interval, when the mobile device is operative in the calling mode or the called mode, transition the mobile device from the calling mode or the called mode to the sleep mode that is transitioned from the calling mode or the called mode in response to receiving the input or detecting the elapse of the predetermined time interval, or when the mobile device is operative in the in-call mode, transition the mobile device from the in-call mode to the sleep mode that is transitioned from the in-call mode in response to receiving the input or detecting the elapse of the predetermined time interval, wherein the mobile device in the sleep mode that is transitioned from the idle mode is configured to consume less power than the idle mode, the mobile device in the sleep mode that is transitioned from the calling mode or the called mode is configured to consume less power than the calling mode or the called mode, and the mobile device in the sleep mode that is transitioned from the in-call mode is configured to consume less power than the in-call mode, wherein the mobile device in the idle mode, the calling mode, or the called mode is configured to consume less power than the in-call mode, and wherein the mobile device in the sleep mode that is transitioned from the idle mode or the sleep mode that is transitioned from the calling mode or the called mode, consumes less power than in the sleep mode that is transitioned from the in-call mode.
