Abstract
En 中文
During the last decade, mobile communications and smartphone technology increasingly became part of people's daily routine. Nowadays, Android smartphones and iPhone are more and more pervasive and widely used even from people with less incomes. Lots of new applications are daily introduced or updated. Such high usage brings new challenges regarding devices' battery lifetime. For smartphone mobile devices and embedded system device, Power Management (PM) it's getting more and more importance because of very limited battery power. There are more and more sensors, I/O and OS SW updates introduced recently in these mobile devices that can be used to improve the effectiveness of PM. In this paper, we do not want to show only the Android smartphones standards regarding power management the system uses, but also to compare the design of Android PM with possibilities that OS middleware libraries/kernel stack offers to reduce it. So, our aim in this paper is to show how kernel level solution can be realized and how. They solutions seems to be CPU less intensive interactions than any other user space or API ones.
