  <!-- Current when CPU is idle -->

  <item name="cpu.idle">0.1</item>

  <!-- Memory bandwidth power values in mA at the rail. There must be one value

       for each bucket defined in the device tree. -->

  <array name="memory.bandwidths">

    <value>22.7</value> <!-- mA for bucket: 100mb/s-1.5 GB/s memory bandwidth -->

  </array>

  <!-- This is the battery capacity in mAh (measured at nominal voltage) -->
