Android App power consumption

Question

How to check the power consumption in each applications in Android?
At least the power consumption should be relative when compared with different applications and these applications might be using any of the services like WIFI,GPS,LCD,wakelock, etc.

Are there any APIs in android regarding the same in order to measure the power consumption for the applications using the above resources?

Answer 1

There is a research paper called “Accurate Online Power Estimation and Automatic Battery Behavior Based Power Model Generation for Smartphones”. For this paper the researchers developed a tool called PowerTutor, the sources of which you can find here. It should be mentioned that your device has to be rooted to use this application.

Answer 2

First, the powertutor from Google Play is out of date. I've checked the source code of it, and find that the power estimation model is for some old mobile models. The value from power tutor is way smaller than the actual power consumption.

Therefore, I would recommend you to use Battery Historian which is developed by google used to estimate battery consumption of each App. But it's written in Python/Go. It will illustrate the hardware invocation in a html file. And you can find battery consumption of each App in a corresponding text file.
