title: Create "Battery usage" intent android
body: <p>On my nexus one, there is a handy app reachable from Settings > About Phone > Battery use.</p>
  
  <p>I'd like to StartActivity() that app from one of my Activities.</p>
  
  <p>I can see in the log that when Settings runs it, this intent is logged:</p>
  
  <pre><code>Starting activity:
    Intent { act=android.intent.action.MAIN
             cmp=com.android.settings/.fuelgauge.PowerUsageSummary }
  </code></pre>
  
  <p>I'm having trouble relating that to something in Android Java source.  I can't even find "fuelgauge" in the GIT source.   Can anyone point me to the right file, or anything else helpful, like how to create the right kind of Intent?</p>
  
  <p>Thanks</p>
  
  <p>Peter</p>
