Abstract

Current mobile devices use a touch boosting scheme to handle operations caused by user interactions with the touchscreen. The current scheme uses a predetermined DVFS step for touch boosting, regardless of user texting speed or related workloads, causing power waste due to unnecessarily high CPU frequency. In particular, the current mechanism is not optimized for power usage when the soft keyboard is used as an input mechanism. In this paper, we propose a scheme called Tbooster, which adaptively adjusts touch boosting level. The scheme reflects texting interval and texting latency, minimizing power consumption while maintaining the user's quality of experience. The scheme was implemented in Android devices and evaluated using a variety of texting applications. Our evaluation results show that the proposed technique reduces the device's overall power consumption by 4.6-13.1%, depending on texting interval and application type.
