  <p>The <code>dumpsys batterystats</code> command generates interesting
  statistical data about battery usage on a device, organized by unique user
  ID (UID). The statistics include the following:</p>

  <ul>
    <li>History of battery-related events</li>

    <li>Global statistics for the device</li>

    <li>Approximate power use per UID and system component</li>

    <li>Per-app mobile milliseconds per packet</li>

    <li>System UID aggregated statistics</li>

    <li>App UID aggregated statistics</li>
  </ul>

  <p>Use the <a href="https://github.com/google/battery-historian">Battery
  Historian</a> tool on the output of the dumpsys command to generate an HTML
  visualization of power-related events from the logs. This information makes it
  easier to understand and diagnose battery-related issues.</p>

  <h2 id="command-line_options">Command input</h2>
  <p>The basic <code>batterystats</code> command is:</p>
  <pre class="prettyprint">
$ adb shell dumpsys batterystats</pre>
  <p>Supported options:</p>
  <ul>
  <li><code>--help</code> displays additional options for tailoring the output.
  </li>
  <li><code>--checkin</code> exports results in machine-readable csv format.
  </li>
  </ul>
  <p>For example, to print battery usage statistics in csv format for all apps
  since the device was last charged, run the command:</p>
  <pre class="prettyprint">
$ adb shell dumpsys batterystats --charged --checkin</pre>
  <p>You can also specify a package name to get statistics for a single app. For
  example, to print battery usage statistics for a given app package
  since the device was last charged, run the command:</p>
  <pre class="prettyprint">
$ adb shell dumpsys batterystats --charged &lt;package-name&gt;</pre>

  <h2 id="output">Command output</h2>

  <p>The <code>batterystats</code> command generates aggregated observations
  about battery use on the device since it was last charged. Observations may be
  per-UID or system-level; data is selected for inclusion based on its
  usefulness in analyzing battery performance. Output includes one (1) entry
  per observation, and each entry consists of a comma-separated list of values
  in the format:
  <em>int</em>,<em>uid</em>,<em>mode</em>,<em>section</em>,<em>fields</em>
  (one or more).</p>

  <p>The first four values correspond to the following:</p>

  <ul>
    <li>Dummy integer</li>

    <li>UID</li>

    <li>Aggregation mode

      <ul>
        <li>"i" for information not tied to charged/uncharged status.</li>
        <li>"l" for --charged (usage since last charge).</li>
        <li>"u" for --unplugged (usage since last unplugged). Deprecated in
        Android 5.1.1.</li>
      </ul>
    </li>

    <li><a href="#interpreting_the_output">Section identifier</a>, which
    determines how to interpret subsequent values in the line.</li>
  </ul>

<h2 id="wifi-reqs">Wi-Fi, Bluetooth, and cellular usage</h2>

<p>Support for battery usage data on Wi-Fi, Bluetooth, and cellular data
requires that the device Wi-Fi, Bluetooth, and cellular chipsets implement radio
support and the chipset firmware passes usage data to the framework. OEMs must
work with their chipset providers to facilitate in-field firmware updates on
existing chipsets and compatible firmware on new chipsets.</p>

<p>Additionally, OEMs must continue to configure and submit the power profile
for their devices. However, when the platform detects that Wi-Fi and Bluetooth
radio power data is available from the chipset, it uses chipset data instead of
power profile data (cell radio power data is not yet used).</p>

<p class="note"><strong>Note</strong>: Prior to Android 6.0, power use for Wi-Fi
radio, Bluetooth radio, and cellular radio was tracked in the <em>m</em> (Misc)
section category. In Android 6.0 and higher, power use for these components is
tracked in the <em>pwi</em> (Power Use Item) section with individual labels
(<em>wifi</em>, <em>blue</em>, <em>cell</em>) for each component.</p>
