碩士 === 國立臺灣大學 === 資訊工程學研究所 === 102 === Smartphones have become an essential part of our daily life. As mobile devices and appli- cations keep becoming more powerful and complicated, the demand for energy on mobile devices also rise continuously. Due to the limited battery capacity, power consumption analysis has been an essential study to make the usage of energy more efficient. In this work, we propose an power analysis considering user perception to investigate whether energy consumption is really worthy to users. We propose the concept of Unperceived Activity and waste of energy caused by it. A series of experiments is conducted to prove the seriousness of waste and find out the sources and characteristics of different unperceived activities. Potential directions are suggested to solve the problem. Some simple remedies are also implemented and evaluated to be able to reduce the waste effectively.
