Battery monitoring and analysis for android based system

Abstract

Testing of Embedded system have always faced numerous problems with complex architecture of software and hardware combinations. Rapidly growing energy and battery consumption demands of mobile phones are not accomplished with advances in battery technology. Energy consumption is an important issue in android devices for mobile devices having advanced operating system. The lifetime of the battery is more and more important issue for users, for example if Wi-Fi or other applications are used continuously in the mobile, the battery of mobile discharges before its specified time. This paper presents a battery monitoring system which is capable of sensing and monitoring capability of battery of mobile phone, which is used to indicate the battery conditions in any numbers of standby powers. The battery capability is to monitor any number of cells utilizing a frequency-shift-keyed signal to sequentially interrogate each individual cell. This modulated tone responses are used to transmit the data back to the monitoring module. This paper introduces the background service name as Mainactivity. This service provides Power saver for automated power model construction method that uses built-in battery voltage sensors and knowledge of battery discharge behavior to monitor power consumption. To save android applications energy, it is critical to monitor the energy consumption of each application. As a solution to this, process acts as a background process and used to monitor battery power for each application and overall system. It also helps to inform users about the battery usage information and restricting the application which uses excess power.
