Abstract
This application describes methods and apparatus for controlling touchscreen interferences. In one aspect, a wireless power device for receiving charging power via a wireless charging field of a wireless charging device is provided. The wireless power device comprises a sensor circuit configured to detect at least one signal from a touchscreen, the detected at least one signal indicating an interaction with the touchscreen. The wireless power device further comprises a processor circuit configured to determine whether the detected at least one signal is a result of a false contact with the touchscreen resulting from the wireless charging field. The wireless power device further comprises a transmitter circuit configured to transmit, based on determining that the detected at least one signal is a result of the false contact with the touchscreen, a first message to the wireless charging device to lower a strength of the wireless charging field.
