Method and apparatus for controlling charging in electronic device

1. A method for controlling charging in an electronic device, the method comprising:

setting, by the electronic device, an alarm, and entering the electronic device into a suspend mode, when entry into the suspend mode is requested while at, least one battery of the electronic device is in a charging state or in a charging stop state, wherein the alarm generates a wake up signal after a time period set for the alarm elapses;

waking up at least partial structural components of the electronic device, in response to the wake up signal;

determining a status of the at least one battery using the at least partial structural components of the electronic device; and

turning on or off the charging of the at least one battery, according to the determined status of the at least one battery.

2. The method of claim 1 , further comprising resetting the alarm and re-entering the suspend mode.

3. The method of claim 1 , wherein waking up the at least partial structural components of the electronic device comprises:

determining an occurrence reason of the wake up signal when the wake up signal is generated; and

waking up a portion but not all of the structural components of the electronic device for controlling the charging when the determined occurrence reason has a wake up reason by the set alarm.

4. The method of claim 3 , further comprising waking up all of the structural components of the electronic device when the determined wake up reason is a reason other than the wake up reason by the set alarm.

5. The method of claim 1 , wherein turning on or off the charging of the at least one battery comprises:

turning on the charging when the status of the at least one battery satisfies a charging condition set in the electronic device; and

turning off the charging when the status of the at least one battery does not satisfy the charging condition set in the electronic device.

6. The method of claim 1 , further comprising notifying a user when the charging status is turned from on to off or from off to on.

7. The method of claim 1 , wherein determining the status of the at least one battery comprises measuring a temperature of the at least one battery using a temperature sensor.

8. The method of claim 1 , further comprising:

determining whether another alarm different from the alarm is set before setting the alarm; and

storing the another alarm when the another alarm is set.

9. The method of claim 8 , further comprising:

comparing a time period set for the another alarm with the time period set for the alarm; and

when the time period set for the another alarm is less than the time period set for the alarm as a result of the comparison, resetting the alarm after the another alarm is completed, and when the time period set for the alarm is less than the time period set for the another alarm as the result of the comparison, resetting the another alarm after the alarm is completed.

10. An apparatus for controlling charging in an electronic device, the apparatus comprising:

a charging unit which charges at least one battery of the electronic device;

a temperatures sensor which measures a temperature of the at least one battery;

an alarm unit which sets an alarm, wherein the alarm generates a wake up signal after a preset time for the alarm elapses; and

a controller which

activates the alarm unit and controls such that the electronic device enters a suspend mode, when entry into the suspend mode is requested,

wakes up at least a portion of structural components of the electronic device, in response to the wake up signal,

determines the temperature of the at least one battery using the at least partial structural components of the electronic device, and

turns on or off the charging unit, according to the determined temperature.

11. The apparatus of claim 10 , wherein the controller resets the alarm and re-enters the suspend mode.

12. The apparatus of claim 10 , wherein the controller determines an occurrence reason of the wake up signal when the wake up signal is generated, and wakes up the at least a portion but not all of the structural components of the electronic device for controlling the charging when the determined occurrence reason is a wake up reason by the set alarm.

13. The apparatus of claim 12 , the controller wakes up all of the structural components of the electronic device when the determined wake up reason is a reason other than a wake up reason by the set alarm.

14. The apparatus of claim 10 , wherein the controller turns on the charging when the status of the at least one battery satisfies a charging condition set in the electronic device, and turns off the charging when the status of the at least one battery does not satisfy the charging condition set in the electronic device.

15. The apparatus of claim 10 , further comprising a display unit which displays a message that notifies when the charging status is turned from on to off or from off to on.

16. The apparatus of claim 10 , wherein the controller determines whether another alarm different from the alarm is set before setting the alarm, and stores the another alarm and enters the suspend mode when the another alarm is set.

17. The apparatus of claim 16 , wherein the controller compares a preset time for the another alarm with the preset time for the alarm, and resets one of the alarm and the another alarm, when the preset time is greater as a result of the comparison.

18. The apparatus of claim 10 , wherein the temperature sensor is a thermistor.

19. The apparatus of claim 10 , wherein the alarm unit is a real time clock or a timer.

20. A method for controlling charging in an electronic device, the method comprising:

when at least one battery of the electronic device is in a charging state or in a charging stop state, and a request for entering into a suspend mode of the electronic device is received, activating a timer, which is set for a time period, generating a wake up signal after the time period elapses, and entering the electronic device into the suspend mode;

in response to the wake up signal, waking up at least one structural component of the electronic device;

determining a status of the at least one battery using the at least one structural component of the electronic device; and

turning on or off the charging of the at least one battery according to the determined status of the at least one battery.
