The accelerometer automatic calibration method for a mobile device and apparatus are provided. In the example, the signal is received from the accelerometer. A substantially constant state of the signal, as caused by the free fall of the accelerometers are detected. When the signal is maintained constant substantially over the period of time at least a predetermined, measured noise level of a signal. It can be determined and output to the accelerometer compensation signal based on the measured noise level, and thus compensates for the accelerometer to mitigate the noise level. In the examples, the compensation signal may be a reference voltage, a reference frequency, and / or the reference pulse train. In another example, is performed to compensate only when in the noise level of the signal range for a period of at least a predetermined time.
