This work proposes an approach for energy consumption estimation of Android applications based on internal measurement. The proposed approach uses samples of voltage and current extracted from the battery of the Android device driver itself. This approach is able to measure the energy consumption of an Android application, or parts of its code. Experiments demonstrate the proposal and compare its...
The popularity of smartphones -- small computers that run on battery power -- has exploded in the last decade. Unsurprisingly, power consumption is an overarching concern for mobile app developers, who are anxious to learn about power-related problems that are encountered by others. In this paper, we present an empirical study exploring the characteristics of energy-related questions posed in Stack...
Because of losses in electricity conversion and storage only part of the energy taken from the power grid produces useful work in a battery-operated mobile device, the rest evaporates as heat. We analyze the recharging activity of a mobile phone to understand the efficiency of the different units involved (charger, EPM chipset, battery). Our measurements show that the efficiency is quite low, only...
