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

摘要

An electronic device includes a touch screen, a background light, and a proximity sensor. 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.
