A DC power supply, a service battery and a 3–wire charger calibration
cable is needed for this calibration.
Note: The Energy Management Calibration process in WinTesla should only be used
when the factory calibration for some reason is not any longer valid in the phone. The
factory calibration of the phone energy management parameters are more precise, thus it
is possible to obtain better battery performance, when the calibration has been performed
in the factory.
