Android Power Management and Analyses of Power Consumption in an Android Smartphone

Abstract

With the rapid development of Android phones, the users' requirements are increasingly demanding. But the huge power consumption has seriously affected the users' communication demands. In this article, we introduce the power management modules and Wake Lock mechanism of the Android system, and analyze the power consumption of it. And we used DC power sources to measure the power consumption of every hardware modules of Android phones. The analysis of measured power consumption data could produce possible Android power-saving modes or a low power consumption mechanism, or lead us to the design of a new power consumption monitoring and power-saving software for Android. Finally, we summarize Android power management and make a prospect on the uncompleted work of Android power consumption monitoring software models.
