Abstract

A charge evaluating method for a mobile phone is provided. The method includes calculating a final charge value A of a mobile phone battery when charging is complete according to a charge value prior to the battery being charged by the battery charger, a charge current value, a power dissipation value and a charging time. The method further includes converting the final voltage value to a final charge value B of the mobile phone battery, and displaying the final charge value A if the final charge value B is more than the final charge value A.

Claims

1. A charge evaluating system for a mobile phone, the mobile phone comprising a battery wherein the battery is charged via a battery charger, the charge evaluating system comprising:

a converting module configured for obtaining a voltage value of the battery prior to the battery being charged by the battery charger upon the condition that the battery charger is activated to charge the battery, and configured for converting the voltage value to a charge value prior to the battery being charged by the battery charger;

an obtaining module configured for obtaining a charge current value of the battery from the battery charger;

a calculating module configured for calculating a power dissipation value of the battery, and for calculating a charging time of the battery by the battery charger;

an evaluating module configured for calculating a final charge value A of the battery upon the condition that a charging of the battery is complete, wherein the final charge value A is calculated according to the charge value prior to the battery being charged by the battery charger, the charge current value, the power dissipation value, and the charging time;

the converting module further configured for obtaining a final voltage value of the battery upon the condition that the charging of the battery is complete, and configured for converting the final voltage value to a final charge value B of the battery;

a determining module configured for determining if the final charge value B of the battery is more than the final charge value A; and

a displaying module for displaying the final charge value A upon the condition that the final charge value B is more than the final charge value A, and for displaying the final charge value B upon the condition that the final charge value B is not more than the final charge value A.

2. The charge evaluating system as claimed in claim 1, wherein the final charge value A of the battery is substantially equal to a result of an equation:

the charge value+(the charge current value−

the power dissipation value)*the charging time.

3. A charge evaluating method for a mobile phone, the mobile phone comprising a battery wherein the battery is charged via a battery charger, the method comprising:

obtaining a voltage value of the battery prior to the battery being charged by the battery charger upon the condition that a charger is activated to charge the battery, and converting the voltage value to a charge value prior to the battery being charged by the battery charger;

obtaining a charge current value of the battery from the battery charger;

calculating a power dissipation value of the battery;

calculating a charging time of the battery by the battery charger;

calculating a final charge value A of the battery upon the condition that a charging of the battery is complete, wherein the final charge A of the battery is calculated according to the charge value prior to the battery being charged by the battery charger, the charge current value, the power dissipation value, and the charging time;

obtaining a final voltage value of the battery upon the condition that the charging of the battery is complete, and converting the final voltage value to a final charge value B of the battery;

determining if the final charge value B of the battery is more than the final charge value A;

displaying the final charge value A upon the condition that the final charge value B is more than the final charge value A; and

displaying the final charge value B upon the condition that the final charge value B is not more than the final charge value A.

4. The method as claimed in claim 3, wherein the final charge value A of the battery is substantially equal to a result of an equation:

the charge value+(the charge current value−

the power dissipation value)*the charging time.
