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 Powersaver
for automated power model construction method that uses builtin
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.
