​Mobile phones and tablets can be considered as the first incarnation of the post-PC era. Their explosive adoption rate has been driven by a number of factors, with the most significant influence being touch-screens, sensors, app markets, and better cellular technologies. However, mobile apps impose an unnecessary signaling and spectrum overhead in the already limited cellular network and battery life of the devices. In this talk, we will characterize and discuss the reasons behind such inefficiencies, covering from background networking activity to keep TCP connections alive to mobile advertisement modules.
