While great strides have been made in measuring energy consumption through
accurate energy models, measures of energy consumption alone are not
sufficient to enable effective energy management on battery-constrained
mobile devices. What is urgently needed is a way to put energy consumption in
context by measuring the value delivered by mobile apps. An accurate value
measure would enable cross-app comparison, app improvement, energy virus
detection, and effective runtime energy allocation and prioritization. Given
that gains in modeling will be lost without a measure of value, we believe
that this is the most important open problem in energy management. Our paper
motivates the problem, describes requirements for a candidate value measure,
discusses possible inputs to such a metric, and presents result from a
preliminary (unsuccessful) attempt to formulate a value measure.
