    Abstract: Disclosed is an electronic device including a processor configured to set a wake-up luminance of a display, based on a wake-up illuminance, to set, upon detecting an illuminance change through the illuminance sensor, a first target luminance of the display by using a first threshold illuminance value at a time point of detecting the illuminance change, to identify whether a flag setting related to an update of a threshold illuminance value is changed, while changing a luminance of the display based on the first target luminance, to determine the first target luminance as a final luminance of the display when there is no change in the flag setting, to update the first threshold illuminance value to a second threshold illuminance value when there is a change in the flag setting, and to change a target luminance of the display from the first target luminance to a second target luminance by using the second threshold illuminance value.

    Abstract: An electronic device includes a housing including a first plate, a second plate spaced apart from the first plate and facing the first plate, and a side member at least partially surrounding a space between the first plate and the second plate, a display located in the space and visible through the first plate, a conductive coil parallel to the second plate and disposed between the display and the second plate, a wireless charging circuit electrically connected to the conductive coil, and a processor operationally connected with the display and the wireless charging circuit. The processor receives a power control signal from an external device, applies a charging current to the conductive coil, based on the power control signal, senses whether a specified event occurs while the charging current is applied, and when the specified event occurs, transmits information for setting a charging power corresponding to the specified event to the external device.

    Abstract: An electronic device and a method operative therein monitor automatic wakeup events that occur during a power save mode. Wakeup events are monitored for respective applications executable within the electronic device. Applications with processing activity during the power save mode are then listed, on the basis of at least the monitored wakeup events. An indication of which apps are consuming battery power during the power save mode can then be obtained.
