An electronic device is provided. The electronic device includes a housing, a power interface exposed through at least a portion of the housing to be connected to an external power source in a wired manner or disposed inside the housing to be connected to the external power source in a wireless manner, at least one battery disposed inside the housing and electrically connected to the power interface, a processor disposed inside the housing and operatively connected to the power interface, and a memory disposed inside the housing and operatively connected to the processor. The memory stores instructions that, when executed, causes the processor to, in a state in which an external power is supplied through the power interface, when a voltage of the battery reaches a first voltage value, lower the voltage of the battery to a second voltage value lower than the first voltage value by discharging the battery after a first time has elapsed from a time point at which the voltage of the battery reaches the first voltage value.

Method of controlling charging of battery and electronic device to which the method is applied

A method and an apparatus for detecting a battery state of an electronic device are provided. The electronic device includes a battery, a charger circuit for charging the battery, a measurement circuit for checking a state of the battery, and a processor configured to charge the battery using the charger circuit, determine whether the charging operation satisfies a preset condition, when the charging operation satisfies the preset condition, obtain first state information of the battery using the measurement circuit, determine an abnormal state of the battery at least based on a difference between the first state information and second state information which is obtained when the preset condition is satisfied before the first state information is acquired, and output notification information regarding the abnormal state.

Method and apparatus for determining abnormal state of battery

According to various embodiments of the present invention, an electronic device includes: a display; a near-field wireless communication circuit configured to repetitively transmit a scan signal for finding an access point; a processor electrically connected to the communication circuit; and a memory electrically connected to the processor, wherein, during execution, the memory can store commands for allowing the processor to set a transmission period of the scan signal as a first period, to determine whether it is necessary to adjust a scan frequency on the basis of a trigger for turning on the display when the display is turned on, to maintain the transmission period as the first period when the scan frequency adjustment is not necessary, and to change the transmission frequency to a second period shorter than the first period, when the scan frequency adjustment is necessary.

Scan method in near-field wireless communication network and electronic device for implementing same

A method and an apparatus for reducing power consumption of an electronic device are provided. The method includes executing an app in response to a first user input and switching the app to a background in response to a second user input. The method also includes confirming whether the app that has been switched to the background satisfies at least one condition and automatically limiting an operation of the app when the app that has been switched to the background satisfies the at least one condition. A result of the automatically limiting operation the operation of the app is displayed.

Electronic device and method for operating the same

A method is provided comprising: detecting an electrical connection between a first device having a first battery and a second device having a second battery; receiving an indication of a residual power of the second battery; displaying, by the first device, a power sharing interface based on the indication of the residual power of the second battery; detecting an input to the interface specifying a threshold amount of power; transmitting power from the first battery to the second device until the threshold amount of power is transmitted.
