Method and apparatus for reducing power consumption of mobile phone and mobile phone

摘要

A method for reducing power consumption of a mobile phone, comprising: activating a proximity sensor of a mobile phone when a call is originated or received (step 101, step 203); obtain a weighted acceleration of the mobile phone using a sensor (step 102, step 204) of acceleration; determine a connection time point of the proximity sensor according to the weighted acceleration of the mobile phone (step 103, step 204); and connect the proximity sensor at the connection time point so that a mobile phone backlight is switched on or off according to a sensor detection result (step 104, step 205) of proximity, in which to activate the sensor proximity is an action at the beginning of a conversation process and disconnection of the proximity sensor is a periodic action in the conversation process, in which the determination of the connection time point of the proximity sensor according to the acceleration Weighted mobile phone comprises: being a shorter time interval if the weighted acceleration of the mobile phone is greater, in which the time interval refers to a time segment from the disconnection of the proximity sensor to the connection of the proximity sensor ; and be the greater time interval if the weighted acceleration of the mobile phone is smaller, in which the connection time point is a time point when the time interval expires after a disconnection time point of the proximity sensor.
