Survey on adaptation techniques of energy consumption within a smartphone

The energy consumption into a smartphone is defined by the energy cost necessary for the components equipment to achieve their activities. This activity is induced by software executions related to users' activity. Indeed, the software produces during a given time an amount of work, (e.g. I/O access, and data encoding/decoding), that grows the number of operations over inner equipment. In other words, the energy consumption could results from the execution of the different interactions between hardware, software and users which by their behaviors trigger a workload on hardware components. The assessment and measurements of the cost of consumed energy, as well as problems in the methods used for energy optimization, are the main topic of this investigation. As results of this work, we conclude that some of the investigated techniques are more accurate than the others for tracking the main sources or equipment responsible of consuming energy.
