Electronic device and method for adjusting amount of electric power supplied to proximity sensor of the electronic devic

An electronic device, comprising:

• a touch screen;
• a background light;
• a proximity sensor;
• a processor;
• a storage device that stores one or more programs, when executed by the processor, causing the processor to perform operations:
• setting a default value for an amount of electric power supplied to the proximity sensor and a rule for adjusting the amount of electric power supplied to the proximity sensor;
• enabling the electronic device to supply the proximity sensor with the amount of electric power having the default value, in response to a calling function of the electronic device being enabled;
• determining if the proximity sensor detects an object near the touch screen with the amount of electric power having the default value;
• increasing the amount of electric power supplied to the proximity sensor according to the rule in response to determining that the proximity sensor detects no object with the amount of electric power having the default value, or decreasing the amount of electric power supplied to the proximity sensor according to the rule in response to determining that the proximity sensor detects an object with the amount of electric power having the default value.

A non-transitory computer-readable medium having stored thereon instructions that, when executed by a processor of an electronic device, causing the processor to perform operations:

• setting a default value for an amount of electric power supplied to the proximity sensor and a rule for adjusting the amount of electric power supplied to the proximity sensor;
• enabling the electronic device to supply the proximity sensor with the electric power having the default value, in response to a calling function of the electronic device being enabled;
• determining if the proximity sensor detects an object near a touch screen of the electronic device with the amount of electric power having the default value;
• increasing the amount of electric power supplied to the proximity sensor according to the rule in response to determining that the proximity sensor detects no object with the amount of electric power having the default value, or decreasing the amount of electric power supplied to the proximity sensor according to the rule in response to determining that the proximity sensor detects an object with the amount of electric power having the default value.
