The electronic device sets 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. When a calling function of the electronic device is started, the electronic device is enabled to supply the proximity sensor the amount of electric power having the default value, and determines if the proximity sensor detects an object near the touch screen with the amount of electric power having the default value. The electronic device increases or decreases the amount of electric power supplied to the proximity sensor according to the rule. ## Claims ### Claim 1 A method for adjusting an amount of electric power supplied to a proximity sensor by an electronic device, comprising: 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. ### Claim 2 (depends on 1) The method as claimed in claim 1, further comprising: shutting down a background light of the electronic device and locking the touch screen in response to determining that the proximity sensor detects an object with the amount of electric power having the default value. ### Claim 3 (depends on 1) The method as claimed in claim 1, wherein the rule is set as adjusting the amount of electric power supplied to the proximity sensor by a preset value. ### Claim 4 (depends on 1) The method as claimed in claim 1, wherein the electric power supplied to the proximity sensor has a minimum value and a maximum value, and the default value is set between the minimum value and the maximum value. ### Claim 5 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. ### Claim 6 (depends on 5) The electronic device as claimed in claim 5, wherein the operations further comprise: shutting down a background light of the electronic device and locking the touch screen in response to determining that the proximity sensor detects an object with the amount of electric power having the default value. ### Claim 7 (depends on 5) The electronic device as claimed in claim 5, wherein the rule is set as adjusting the amount of electric power supplied to the proximity sensor by a preset value. ### Claim 8 (depends on 5) The electronic device as claimed in claim 5, wherein the electric power supplied to the proximity sensor has a minimum value and a maximum value, and the default value is set between the minimum value and the maximum value. ### Claim 9 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. ### Claim 10 (depends on 9) The medium as claimed in claim 9, wherein the operations further comprise: shutting down a background light of the electronic device and locking the touch screen in response to determining that the proximity sensor detects an object with the amount of electric power having the default value. ### Claim 11 (depends on 9) The medium as claimed in claim 9, wherein the rule is set as adjusting the amount of electric power supplied to the proximity sensor by a preset value. ### Claim 12 (depends on 9) The medium as claimed in claim 9, wherein the electric power supplied to the proximity sensor has a minimum value and a maximum value, and the default value is set between the minimum value and the maximum value.
