How to estimate power consumption of an Android app? Is it linear?
<p>I do a few of experiments and find I can't estimate power consumption of an app.</p>

<p>e.g.: I find it is <em>100mW</em> when I just run my app, and it is <em>20mW</em> when I do nothing. I think <em>80mW</em> is consumed by my app. But it is <em>200mW</em> I run another app B and my app also run, and it is <em>160mW</em> when I just run app B, so my app also consume <em>40mW</em>? Which one is correct?</p>

<p>In my eyes, it relate to CPU load rate, or something other I don't know. So we can not estimate power consumption by subtraction because it's not linear. So I want to know how to estimate power consumption correctly?</p>

<p>Any advice is welcome.</p>
