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