1. An electronic device comprising: a plurality of group sensors positioned at a first location, a second location, and a third location, wherein each group sensors includes at least one temperature sensing device at or proximate to the exterior surface of the electronic device; an operational amplifier, coupled to the plurality of group sensors, that generates an output signal based on distribution of temperature at the first location, the second location, and the third location; a memory device that stores a look-up table having expected thermal difference values corresponding to a plurality of different operation modes of the electronic device, wherein expected thermal difference values in the look-up table indicate different temperature differentials that correspond to an expected measurement based on at least two of the plurality of group sensors; and at least one processing device that receives the output signals from the operational amplifier and determines, based at least in part on a current operation mode of the electronic device included in the plurality of different operation modes, an operational context of the electronic device based at least upon the output signal and at least one of the expected thermal difference values stored in the look-up table that corresponds to the current operation mode.
