Abstract
A method and a system for reducing current noise of a touch terminal are provided. The method includes: determining that a user receives a voice call via an earpiece of the touch terminal, and controlling the touch terminal to switch from a first touch scan frequency to a second touch scan frequency, where the second touch scan frequency is less than the first touch scan frequency. As can be seen, if the user receives the voice call via the earpiece of the touch terminal, the touch terminal is controlled to switch from the first touch scan frequency to the second touch scan frequency, to effectively reduce the current noise heard by the user by decreasing the touch scan frequency of the touch terminal, so that the periodic current noise is outside a frequency band perceptible to a human ear, thereby improving user experience when receiving the voice call.
