高效管理能源对现代智能手机来说至关重要。各种各样的无线接口和传感器，以及利用这些资源的耗电应用的日益普及，可以将移动手持设备的电池寿命缩短到几个小时。研究团体、操作系统和硬件供应商发现了有趣的优化和技术来延长手机的电池寿命。然而，锂离子电池的技术水平清楚地表明，能源效率必须在硬件和软件层面上实现。在本调查中，我们将涵盖1999年至2011年5月之间的研究文献中可以在六个不同层面上找到的软件解决方案：能源感知操作系统，高效资源管理，用户与移动设备和应用程序交互模式的影响，无线接口和传感器管理，最后是将移动设备与云计算服务集成的好处。
Managing energy efficiently is paramount in modern smartphones. The diverse range of wireless interfaces and sensors, and the increasing popularity of power-hungry applications that take advantage of these resources can reduce the battery life of mobile handhelds to few hours of operation. The research community, and operating system and hardware vendors found interesting optimisations and techniques to extend the battery life of mobile phones. However, the state of the art of lithium-ion batteries clearly indicates that energy efficiency must be achieved both at the hardware and software level. In this survey, we will cover the software solutions that can be found in the research literature between 1999 and May 2011 at six different levels: energy-aware operating systems, efficient resource management, the impact of users' interaction patterns with mobile devices and applications, wireless interfaces and sensors management, and finally the benefits of integrating mobile devices with cloud computing services.
