摘要: | 如智慧型手機等的行動系統已成為現代人生活中不可或缺的一部份。由於行動裝置
上電池容量相當的有限,如何了解系統中的耗電分布並減少不必要的耗電一直是重 要的課題。在考慮使用者觀感(User Perception)的情況下,我們發現目前的行動系統 很可能存在嚴重的耗電浪費。因此我們提出了隱性活動(Unperceived Activity)的概 念,並設計一連串的提驗及分析,證明其嚴重性,並觀察發生的原因和特性。根據 分析的結果,我們提出並實作了可能的解決方向,並在驗證實驗中證明這些方法可 以達到可觀的省電效果。 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. |
