    Abstract: One embodiment relates to testing and verifying vibrator motor operation during manufacturing of a device and during in-the-field use. The test relies on an integrated motion sensor or other mechanical measurement circuitry, such as, for example, an accelerometer. In one embodiment, a speed determination for a vibrator motor performance during initial manufacture of the device. Subsequently, when vibration is detected during the in-the-field use, the vibration may be sampled using the integrated mechanical measurement circuitry. Once sampled, a speed may be determined based on a resonance of the sampled signal. Over time, the various speed determinations for the vibrator motor may be analyzed to determine an overall health of the vibrator motor. A threshold for detecting when the overall health of the vibration motor over time has degraded may be predetermined. A notification of a degradation of vibrator motor performance is sent to either a manufacturer or user of the mobile communications device. Other embodiments are described and claimed.
