appscope-analyzer
appscope-analyzer is a command-line tool that parses the AppScope logs
and produces per process (PID) or per application (UID) power consumption
information
About AppScope
AppScope is an application energy metering framework for Android smartphones using kernel activity monitoring.
Understanding the energy consumption of a smartphone application is a key area of interest for end users, as well as application and system software developers. Other similar work has only been able to provide limited information concerning the energy consumption of individual applications because of limited access to underlying hardware and system software. The energy consumption of a smartphone application is, therefore, often estimated with low accuracy and granularity. AppScope is an Android-based energy metering system. This system monitors application’s hardware usage at the kernel level and accurately estimates energy consumption. AppScope is implemented as a kernel module and uses an event-driven monitoring method that generates low overhead and provides high accuracy. Our preliminary evaluation results indicate that AppScope accurately estimates the energy consumption of Android applications expending approximately 35mW and 2.1% in power consumption and CPU utilization overhead, respectively.
Installing appscope-analyzer
appscope-analyzer requires Python 2.5 or newer, and some form of UNIX-like shell (bash
works well). It works on Linux, OS X, and Windows (with Cygwin).
Installing and setting up appscope-analyzer will take about one minute.
First, download the tool or clone the Mercurial repository. Next, open your ~/.bashrc file and
put an alias there:
alias asa='python ~/path/to/appscope-analyzer.py'
Make sure you run source ~/.bashrc or restart your terminal window to make
the alias take effect.
Using appscope-analyzer
appscope-analyzer is quick and easy to use.
List Monitored Apps
To show a list of the monitored apps use asa -s HT181P8A0128/ -l
PID UID APP PACKAGE

Show Energy Of a Particular App/Process
To show the AppScope energy samples of a spesific app you can use:
asa -s HT181P8A0128/ -u 10066 or
asa -s HT181P8A0128/ -a com.webroot.security

To show the energy samlpes of a spesific process just use:
asa -s HT181P8A0128/ -p 344
(-q option will produce an output with only the 'TIME' and 'TOTAL' columns
-v option will produce a more detailed output containing usage information
such as CPU frequency ticks, packets send and received through WIFI, display
usage information etc.)
Tips and Tricks
You can search for a specific pattern in the output by using the
-g option. e.g.
asa -s HT181P8A0128/ -l -g 'google'
