There is described a portable electronic device capable of detecting false wake conditions, and a method thereof. The portable electronic device comprises a sensor circuit and a display. The sensor circuit detects double tap data associated with user input and motion data subsequent to the double tap data within a predetermined time period. The sensor circuit also determines whether the motion data corresponds to at least one criterion associated with non-user input. The display wakes from a sleep state in response to the sensor circuit determining that the motion data corresponds to the at least one criterion. For some embodiments, the sensor circuit includes a motion sensor to detect the motion data and a sensor hub to determine whether the motion data corresponds to the at least one criterion.
