Method of controlling power and electronic device thereof
A portable electronic device supporting wireless electronic communication comprises a display, at least one sensor device, a protective cover and a processor. The protective cover is mounted to selectively cover portions of the display and the at least one sensor device detects an object located in proximity of the electronic device. The processor controls transmission power in response to detection of the object located in proximity of the electronic device by the sensor device and in response to an operation mode associated with the protective cover.
1. A method employed by an electronic device, comprising:
reducing a power transmitted by the electronic device when a proximity detector in the electronic device detects that an object is proximate to the electronic device and a Hall sensor detects that a cover attached to the electronic device is open;
when the Hall sensor detects that the cover attached to the electronic device is closed, determining whether the electronic device is engaged in NFC transmission;
reducing the power transmitted by the electronic device when the determination is negative; and
maintaining a level of power transmitted at a default power level when the determination is positive.
2. The method of claim 1 , further comprises,
when the Hall sensor detects that the cover is closed, determining whether the electronic device is engaged in an infrared communication,
reducing the power transmitted by the electronic device when the determination that the electronic device is engaged in the infrared communication is negative; and
maintaining a level of power transmitted at the default power level when the determination that the electronic device is engaged in the infrared communication is positive.
3. The method of claim 1 , further comprises,
when the Hall sensor detects that the cover is closed, determining whether the electronic device is engaged in a wireless LAN communication,
reducing the power transmitted by the electronic device when the determination that the electronic device is engaged in the wireless LAN communication is negative; and
maintaining a level of power transmitted at the default power level when the determination that the electronic device is engaged in the wireless LAN communication is positive.
4. The method of claim 1 , further comprises,
when the Hall sensor detects that the cover is closed, determining whether the electronic device is engaged in a Zigbee communication,
reducing the power transmitted by the electronic device when the determination that the electronic device is engaged in the Zigbee communication is negative; and
maintaining a level of power transmitted at the default power level when the determination that the electronic device is engaged in the Zigbee communication is positive.
5. An electronic device comprising:
a housing including a display; and
at least one processor included within the housing,
a cover attached to the housing, wherein the cover includes a magnet;
a proximity detector configured to detect an object proximate to the electronic device;
a Hall sensor configured to detect that the cover covers at least a portion of the display;
wherein the at least one processor controls power wherein:
when the Hall sensor detects the cover is open and the proximity detector detects the object in proximity to the electronic device reducing the power by a predetermined value;
when the Hall sensor detects the cover is closed:
maintaining the power at a default power value when the electronic device is engaged in a Near Field Communication (NFC) transmission; and
otherwise reducing the power by the predetermined value.
6. The electronic device of claim 5 , wherein the cover includes one or more transparent windows.
7. The electronic device of claim 6 , wherein the processor enables the display to display status information of the electronic device through the transparent window when the cover is closed and encompasses at least a portion of the electronic device.
8. The electronic device of claim 7 , wherein the status information comprises at least one of, battery charge remaining information, weather information, time information, message reception and confirmation information, current mode indication information and transmission power information.
9. The electronic device of claim 5 , wherein the default power level is between 23 dBm and 29.5 dBm and reducing the power by the predetermined value comprises reducing the power level to between 18 dBm and 22.5 dBm.
