Abstract

Smartphones have emerged as a popular and frequently used platform for the consumption of multimedia. New display technologies, such as AMOLED, have been recently introduced to smartphones to fulfill the requirements of these multimedia applications. However, as an AMOLED screen's power consumption is determined by the display content, such applications are often limited by the battery life of the device they are running on, inspiring many researches to develop new power management schemes. In this work, we evaluate the power consumption of several applications on a series of Samsung smartphones and take a deep look into AMOLED's power consumption and its relative contributions for multimedia apps. We improve AMOLED power analysis by considering the dynamic factors in displaying, and analyze the individual factors affecting power consumption when streaming video, playing a video game, and recording video via a device's built-in camera. Our detailed measurements refine the power analysis of smartphones and reveal some interesting perspectives regarding the power consumption of AMOLED displays in multimedia applications.

智能手机显示应用是如何消耗能源的?

智能手机已经成为一种流行的、经常使用的多媒体消费平台。新的显示技术，如AMOLED，最近被引入智能手机，以满足这些多媒体应用的要求。然而，由于AMOLED屏幕的功耗是由显示内容决定的，这类应用往往受到其所运行设备的电池寿命的限制，这激发了许多研究开发新的电源管理方案。在这项工作中，我们评估了一系列三星智能手机上几个应用程序的功耗，并深入研究了AMOLED的功耗及其对多媒体应用程序的相对贡献。我们通过考虑显示中的动态因素来改进AMOLED功耗分析，并分析流媒体视频、玩视频游戏和通过设备内置摄像头录制视频时影响功耗的各个因素。我们详细的测量细化了智能手机的功耗分析，并揭示了多媒体应用中有关AMOLED显示器功耗的一些有趣的观点。
