A study on identifying battery-draining Android applications in screen-off state

Android OS has a function with which an application can work in screen-off state without user's operation. In this paper, we propose a method for identifying applications which largely drain battery in Screen-off state in Android devices. We monitor the wake-up of Android devices and estimate the power consumption of each application based on the monitoring results. Our experimental results demonstrate that our method can identify power draining applications effectively.
