Energy consumption in hand-held mobile communication devices: A comparative study

It has been observed that for the past few years the use of hand-held smart phone mobile devices has been increasingly popular and common in length and breadth of the globe. These smart devices have penetrated the human societies across the globe they have become an integral part of today's modern-day routine activities. Besides all the inherent benefits these mobile devices suffer from scarce storage capacity, limited processing capability and small battery life. Keeping in these limitations, a total of ten different readily available smart-phones have been considered for measurement of power consumption in each component of the smart-phone. The power consumption of the selected smart-phones has been compared to understand the fact that how different components contribute in overall power consumption. This research work not only assists the users in selection of smart-phones but also guides the researchers to develop techniques that help in reducing energy consumption in smart-phones.
