Power Wasting

[phub]

Hi All,

 

I want to know is there is any android api available which is exposed to developer to get rough estimate about power consumed by application. So it is easier to identify power wasting app.

 

Awaiting for response. Thanks in advance

Now public API. Though the battery consumption screen in the system settings was designed to give this information to the user.

There's no API as such at the moment. Although a lot of work is being carried out into analysing application source to identify areas of high energy consumption. In our lab we're looking at static analysis and profiling tools to aid this. 

Other than that, I used a tool recently by AT&T that profiles apps running in the emulator, reporting back various information about estimated battery consumption etc (http://developer.att.com/developer/forward.jsp?passedItemId=9700312). This may give you a better idea of what's going on.

Hope this helps,

James

Hi.

Check also this research paper: “Accurate Online Power Estimation and Automatic Battery Behavior Based Power Model Generation for Smartphones”. Here is a link: http://powertutor.org/

PowerTutor only works for the phones they have tested as it's using a
customised power model for each one of them using linear regression
techniques. Nevertheless, it should be considered as an estimator as
hardware has so many peculiarities that they cannot easily incorporate
all of them on the power model. If you're using a non-supported phone,
it is very likely that it can return inaccurate values
