Abstract
obviously, our life is becoming more dependent on using smart phones to conduct variety of useful tasks. There are different mobile applications in many aspects of life including education, health, and transportation and many others. Recently, these smart devices are being used increasingly in the health sector to facilitate the medical processes. Besides all these benefits of using smart phones, there are some critical challenges that limit their optimal usage. Among the main challenges, facing the smart phone is the short battery lifetime due to energy consumption especially when running applications with intensive computations. That's true charging up a smart phones requires a negligible amount of power, but it is also true that the heavy energy consumption comes from how those devices are used once they are fully charged. From here comes the motivation to study the power consumption of the smart devices, and mainly smart phones. In this paper, we measured experimentally the power consumption of different components of two brands of smart phones. In addition to the regular components, we also measured the power consumed by the WiFi unit since most of the mobile devices used while they are connected to the Internet. The results were presented and analyzed to get more real estimate and understanding of how these components participate to the overall power consumption of the smart phone. As future work, these results can be used to describe a model for the consumed power by smart phones.
