Is there a way to see the power consumption of an Android process? I have a rooted HTC Hero, and I have developed some native programs in C language. I want to see the power consumptions of these programs. So, I want a way to measure the power consumption in process level and not in application level as e.g. PowerTutor application does..

Is there an API that can help me develop an application that can do this thing? Can I use /proc/ stats etc.?

any ideas on this?

As said here: Android Battery usage profiling

There is a private API, PowerProfile, for retrieving battery consumption on a subsystem level (see http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.2_r1.1/com/android/internal/os/PowerProfile.java). Also take a look at the code for the fuel gauge you find in Android's settings on how they calculate power consumption: http://google.com/codesearch/p?hl=en#ohAXAHj6Njg/src/com/android/settings/fuelgauge/PowerUsageSummary.java

  • If it's correct please mark it to incentive people's answers ;-) – neteinstein May 18 '11 at 23:57
  • Yes, don't worry! I will do it as soon as possible I find that it's correct! :) – Thanasis Petsas May 19 '11 at 10:45
  • `BatteryStats` doesn't provide per-process power consumption estimation. Moreover there are many other disadvantages: update rate problem, information granularity problem and the fact that is implemented in Java (It's a Java class). – Thanasis Petsas Feb 21 '13 at 23:48

AppScope is an application energy metering framework for Android smartphones using kernel activity monitoring. AppScope provides an accurate and detailed both per-application and per-process energy estimation solution.

The current release supports HTC Nexus One only and can be found here.

For more information and technical details about the AppScope framework you can read the AppScope paper presented at USENIX ATC '12, here.
