Abstract: A method and apparatus for distinguishing momentary loss of battery contact from a battery undervoltage condition in a portable device sense the current into the portable device from the battery, and when the current drops to a level indicating that contact with the battery has been lost, the portable device is allowed to operate at a lower voltage than a nominal undervoltage limit of the battery until contact is resumed.
