To measure the power consumed by a mobile device for a specific task

[Kharthik]

Friends,

I need a help regarding my academic project where I am trying to measure the power consumed by a mobile device for a specific task. For example if we are using a calculator application and I perform addition of two numbers. I want to check the power consumed for this particular operation of addition. There are few applications like PowerTutor in Android mobiles, but they give the power consumed by the mobile on whole and not for a specific task. Can you please guide me or provide technical tips on this? Thanks, in advance!

My best guess is that you'll have to break down how much power is consumed per operation and figure out how many operations it takes to add two numbers.

Thank you. My question was is there any set up that can be done or any software that can calculate how much power is consumed per operation.

I think the better question to ask is how much CPU is being used when the application is used? Are you taking the screen being on into account?

I don't know of any programs that could measure things this specifically. You may be better off putting an ampmeter on the contacts of the battery and measuring that way. If you do it that way, you should turn off every other application and antenna on the phone.
