A method and mobile terminal for correcting the power of a mobile terminal is provided, including reading the register of a coulometer chip for acquiring a first power of a battery; matching the first power with a preset power level, each of power levels corresponding to a preset service logic; correcting the first power by a preset service logic matched with the first power to form and display a second power. In this way, it is only necessary to compensate the actual power according to a certain criterion to acquire a second power after the acquisition of the actual power, without need of adding additional devices or changing hardware arrangement in a hardware system, thereby enabling a user to use battery power as much as possible, and reducing unnecessary charging operations.

1. A method for correcting power of a mobile terminal which employs a battery as an energy supply, comprising: reading a register of a coulometer chip for acquiring a first power of the battery;matching the first power with at least one preset power level, respectively, each of the at least one power level corresponding to a preset service logic;correcting the first power by a preset service logic matched with the first power to form a second power and displaying the second power;wherein the forming the second power comprises: reading the register of the coulometer chip for acquiring a first voltage of the battery when the first power is at a lowest level of the at least one power level; filtering the first voltage to form a second voltage; and correcting the first power using the second voltage to form the second power;wherein the reading the register of the coulometer chip for acquiring the first voltage of the battery when the first power is at a lowest level of the at least one power level comprises: reading the first voltage of the battery consecutively, sorting values of various first voltages, removing a largest value and a smallest value, averaging remaining values, and taking a mean value as a value of the second voltage. 2. The method according to claim 1, wherein the displaying the second power comprises: displaying the second power on an interface of the mobile terminal. 3. The method according to claim 1, wherein the preset service logic matched with the first power comprises service logic 1 to 4, wherein: service logic 1 represents that: if the first power 1 (C1)≧100%, the first power being at power level 1, then the second power (C2)=100%;service logic 2 represents that: if 100%>the C1≧30%, the first power being at power level 2, then the C2=(50+((C1*100−30)*5)/7)%;service logic 3 represents that: if 30%>the C1≧7%, the first power being at power level 3, then the C2=(14+((C1*100−7)*35)/22)%; andservice logic 4 represents that: if 7%>the C1≧2%, the first power being at power level 4, then the C2=((C1*100*13)/6)%. 4. The method according to claim 3, wherein the preset service logic matched with the first power also comprises service logic 5, which represents that: when the first power is lower than or equal to 2%, and is at the lowest level of the at least one power level,if a second voltage is higher than a voltage threshold, then the C2=1%,if a second voltage is not higher than the voltage threshold, then the C2=0%, and an operation system is informed to start and execute a shutdown process. 5. A mobile terminal comprising a battery, and also comprising: a memory storing programming instructions; anda processor configured to execute the stored programming instructions to perform steps comprising: reading a register of a coulometer chip for acquiring a first power of the battery;matching the first power with at least one preset power level, respectively, each of the at least one power level corresponding to a preset service logic;correcting the first power by a preset service logic matched with the first power to form a second power and displaying the second power;wherein the forming the second power comprises: reading the register of the coulometer chip for acquiring a first voltage of the battery when the first power is at a lowest level of the at least one power level; filtering the first voltage to form a second voltage; and correcting the first power using the second voltage to form the second power;wherein the reading the register of the coulometer chip for acquiring the first voltage of the battery when the first power is at a lowest level of the at least one power level comprises: reading the first voltage of the battery consecutively, sorting values of various first voltages, removing a largest value and a smallest value, averaging remaining values, and taking a mean value as a value of the second voltage. 6. The mobile terminal according to claim 5, wherein the preset service logic matched with the first power comprises service logic 1 to 4, wherein: service logic 1 represents that: if the first power 1 (C1)≧100%, the first power being at power level 1, then the second power (C2)=100%;service logic 2 represents that: if 100%>the C1≧30%, the first power being at power level 2, then the C2=(50+((C1*100−30)*5)/7)%;service logic 3 represents that: if 30%>the C1≧7%, the first power being at power level 3, then the C2=(14+((C1*100−7)*35)/22)%; andservice logic 4 represents that: if 7%>the C1≧2%, the first power being at power level 4, then the C2=((C1*100*13)/6)%. 7. The mobile terminal according to claim 6, wherein the preset service logic matched with the first power also comprises service logic 5, which represents that: when the first power is lower than or equal to 2%, and when the first power is at the lowest level,if a second voltage is higher than a voltage threshold, then the C2=1%,if a second voltage is not higher than the threshold, then the C2=0% and an operation system is informed to start and execute a shutdown process.
