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 electrically connected with a charger, wherein a controller of the electronic device generates a wake up signal after a time period set for the alarm elapses;
determining an occurrence reason of the wake up signal;
when the determined occurrence reason is a wake up reason by the set alarm, waking up at least partial structural components of the electronic device in response to the wake up signal, without waking up all of the structural components of the electronic device for controlling the charging;
determining a status of the at least one battery using the at least partial structural components of the electronic device; and
controlling the charging of the at least one battery based on the determined status of the at least one battery.

Abstract
A method for controlling charging in an electronic device for managing the electronic device, to stably charge a battery is provided. The method includes setting alarm such that a wake up signal is generated after a time elapses when entry into a suspend mode is requested during charging a battery or in a charging stop state, entering the suspend mode, waking-up and determining a state of the battery wake up, and turning-on or -off the battery charging according to the determined state of the battery.

10. An apparatus for controlling charging in an electronic device, the apparatus comprising:
-
a charging controller configured to charge at least one battery of the electronic device; 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 charging unit 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, and determines a status of the at least one battery using the at least one partial components of the electronic device, controls the charging unit, according to the determined status of the at least one battery, determines an occurrence reason of the wake up signal when the wake up signal is generated, and when the determined occurrence reason is a wake up reason by the set alarm, wakes up the at least the portion of the structural components of the electronic device, without waking up all of the structural components of the electronic device for controlling the charging. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
