In certain example embodiments, the energy-using component comprises a heater element, and the controlled operation comprises changing an operating state of the heater element between one or more of: an energized state and a deenergized state; a deenergized state and an energized state; or a partially energized state. In certain example embodiments, the monitored at least one environmental characteristic is one or more of: a temperature; a humidity; a relative humidity; or a dew point. In certain example embodiments, a sensor is operable for measuring a temperature of the mobile device. In certain example embodiments, the determining of the action involves computing a dew point based on the sensed mobile device characteristic and the monitored at least one environmental characteristic. In certain example embodiments, the device further has at least one network interface operable for exchanging data signals with the processor, and with a network, the data signals relating to one or more of: the monitoring of at least one environmental characteristic of at least two environments in which the mobile device is operable; the tracking of the location of the mobile device in relation to the at least two environments; or the informing of the mobile device with the data relating to the at least one environmental characteristic of the environment in which the mobile device is located.
In certain example embodiments, the mobile device further has a case disposed about and encasing a plurality of components of the mobile device; and an optically transparent window disposed within the case; where the energy-using component is operable for deterring one or more of a fog condensation or a frost deposit upon the optically transparent window.
