With the rapid development of mobile Internet technology,Android smart phone provides convenient services for people s daily life with its powerful functions. However, the energy resource of Android applications is very limited. The energy consumption of Android applications will directly affect battery life. Therefore,the energy bugs of Android applications are greatly concerned by the researchers,and quite a few of technologies and correlated tools have been proposed and developed. This paper outlines the correlated research methods and tools for energy bugs analysis of Android applications and summarises the problems in recent studies, as well as discusses the research directions in the future.
