Abstract

The invention discloses a method for mobile terminal to update the electric quantity of a battery and the mobile terminal. The method comprises the steps that the battery voltage is collected when the mobile terminal system is started, and the original electric quantity of the battery is obtained through a pre-established voltage and electric quantity conversion table; the current battery voltage is collected to obtain the current collected electric quantity of the battery, and theoretical charging-discharging electric quantity of the battery of the mobile terminal is calculated according to a collection time interval; the collected electric quantity is compared with the original electric quantity, and whether the collected electric quantity is the real current electric quantity of the battery or not is judged in combination with the theoretical charging-discharging electric quantity; and if not, the real current electric quantity of the battery is estimated according to the theoretical charging-discharging electric quantity; and the original electric quantity is updated to the real current electric quantity of the battery and distributed to each functional module of the mobile terminal system. The method has the advantages that the real current electric quantity of the battery is accurately obtained through a battery charging-discharging pre-estimation mechanism, thereby effectively avoiding abnormal fluctuation phenomena from occurring when the electric quantity of the battery is updated by the mobile terminal.
