As received, the device was interrogated, and battery had reached end of life (eol) level.A product code download was attempted but was unsuccessful due to low battery level.The device was cut open to enable further testing and an external power supply was connected to power the device.Analysis performed with external power supply found high current drain from the hybrid circuitry.Further isolation of hybrid current leakage was performed, and results were consistent with xena integrated circuit anomaly resulting in the reported anomaly.An assessment of total projected longevity was performed, and premature battery depletion was confirmed.
