title = "Parallel data transfer with voice calls for energy-efficient mobile services",
abstract = "Battery consumption is one challenge for mobile applications and\textbackslash{}nservices. In this paper we explore the scenario where mobile phones\textbackslash{}ndelay the transfer of non-urgent data and perform the communication\textbackslash{}nwhile a voice call is active. Our measurements show that data transfer\textbackslash{}nduring voice call requires only slightly over 10\% additional power and\textbackslash{}nthat simultaneous voice call slows down the file transfer by 3\%-14\%.\textbackslash{}nAs a result we can save over 80\% of energy in data transfer if we can\textbackslash{}ndelay the communication to a time when user is speaking at the mobile\textbackslash{}nphone. For a user speaking 26 minutes a day this would allow 50MB of low\textbackslash{}nenergy data communication. A large class of applications can delay their\textbackslash{}ndata transfer without major effect to the user experience. The power\textbackslash{}nsaving mechanism can be implemented either in an application specific\textbackslash{}nfashion or, preferably, at the middleware layer.",
