7. The mobile electronic device of claim 1 , wherein:

when the power supplied to the battery is interrupted before the battery is at the second charging percentage rate, the processor switches to a power supply wait state, and

when the power to the battery is available in the power supply wait state, the processor determines the second charging percentage and resumes charging the battery to the determined second charging percentage.

8. The mobile electronic device of claim 1 , wherein during the charging of the battery, the processor receives, from a user, an input of a third charging percentage higher than the second charging percentage through adjustment of a charging percentage rate of the battery displayed on a battery management screen, and further charges the battery to the input third charging percentage.

9. A mobile electronic device comprising:

a battery;

a display; and

a processor configured to:

display a battery management screen for adjusting a charging percentage of the battery;

adjust the charging percentage of the battery displayed on the battery management screen when a user input is detected on the display;

control charging the battery to a second charging percentage lower than a first charging percentage indicating a fully charged state of the battery that was previously set; and

control to stop charging the battery when a current percentage of the battery reaches the second charging percentage.

10. The mobile electronic device of claim 9 , wherein the processor displays at least one of information related to the charging of the battery, information related to an expected charging time, and information related to an elapsed charging time on a battery management screen when charging the battery at the second charging percentage.

11. A battery management method for a mobile electronic device, comprising:

controlling charging a battery to a second charging percentage that is lower than a first charging percentage indicating a fully charged state of the battery that was previously set when power is applied to the battery;

controlling display of the second charging percentage on a display of the mobile electronic device; and

controlling to stop charging the battery when a current charging percentage of the battery reaches the second charging percentage.

12. The battery management method of claim 11 , further comprising:

determining the second charging percentage using a temperature sensed by the mobile electronic device; and

displaying at least one of information related to the charging of the battery, information related to an expected charging time, and information related to an elapsed charging time.

13. The battery management method of claim 11 , further comprising:

sensing a battery temperature using at least one sensor mounted in the mobile electronic device.

14. The battery management method of claim 11 , wherein controlling charging the battery to the second charging percentage comprises:

identifying a current temperature of the battery from a sensed temperature; and

controlling charging the battery to the second charging percentage by using at least one of a battery charging percentage when a charging current is changed, a battery charging percentage at a full-charging cutoff voltage, and a current battery temperature.

15. The battery management method of claim 11 , wherein controlling charging the battery to the second charging percentage comprises:

changing the second charging percentage according to a changed temperature of the battery when the temperature of the battery is changed by a reference temperature change value or more during the charging of the battery; and

controlling charging the battery to the changed second charging percentage; and

controlling to stop charging the battery when a current charging percentage of the battery reaches the second charging percentage.

16. The battery management method of claim 11 , wherein controlling charging the battery to the second charging percentage comprises:

switching to a power supply wait state when the power supplied to the battery is interrupted when a battery capacity is not at the second charging percentage;

resuming charging the battery when the power is available to charge the battery in the power supply wait state; and

controlling charging the battery to the second charging percentage.

17. The battery management method of claim 11 , wherein controlling charging the battery to the second charging percentage comprises:

receiving, from a user, an input of a third charging percentage higher than the second charging percentage through adjustment of a charging percentage of the battery displayed on a battery management screen during the charging of the battery; and

further controlling charging the battery to the input third charging percentage.

18. A battery management method for a mobile electronic device, comprising:

displaying a battery management screen for adjusting a charging percentage of the battery on a display of the mobile electronic device;

adjusting the charging percentage of the battery displayed on the battery management screen when a user input is detected on the mobile electronic device;

setting the adjusted charging percentage to a second charging percentage lower than a first charging percentage indicating a fully charged state of the battery that was previously set;

controlling charging the battery to the set second charging percentage; and

controlling to stop charging the battery when a current charging percentage of the battery reaches the second charging percentage.

19. The battery management method of claim 18 , further comprising:

displaying at least one of information related to the charging of the battery, information related to an expected charging time, and information related to an elapsed charging time on the battery management screen.
