A use state statistic compilation method for a power level monitoring technique and a mobile phone. The method comprises: recording a screen-off power consumption threshold of a mobile phone, recording an application that must be kept running on the mobile phone (S101); determining whether the mobile phone is currently in a screen-off state (S103); if not, maintaining the current state (S103); if yes, determining whether the current power consumption of the mobile phone is greater than the screen-off power consumption threshold (S104); if not, maintaining the current state (S105); and if yes, closing all applications on the mobile phone other than the application that must be kept running and transmitting technical usage data to a manufacturer-preset data collecting terminal (S106). With the use state statistic compilation method for the power level monitoring technique and the mobile phone, by means of monitoring the power consumption when the mobile phone is in the screen-off state, once the screen-off powe
