+ <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 class="note">You can 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 for
+ you to understand and diagnose any battery-related issues.</p>
+
+ <h2 id="command-line_options">Command line options</h2>
+
+ <p>Use the <code>--help</code> option to learn about the various options
+ for tailoring the output.</p>
+
+ <p>Use the <code>--checkin</code> option to get the results in
+ machine-readable csv format.</p>
+
+ <p>To print battery usage statistics for a given app package since the
+ device was last charged, run this command:</p>
+ <pre class="prettyprint">
+$ adb shell dumpsys batterystats --charged <package-name>
+ </pre>
+
+ <h2 id="sample_input">Input</h2>
+
+ <p>To print battery usage statistics for all apps since the device was last

+ <pre class="prettyprint">
+$ adb shell dumpsys batterystats --charged --checkin
+ </pre>
+
+ <h2 id="output">Output</h2>

<h2 id="viewing-usage">Viewing Battery Usage Data</h2>
-<p>The <code>dumpsys</code> <code>batterystats</code> command generates interesting statistical data
-about battery usage on a device, organized by unique application ID. You can view a history of
-battery-related events such as mobile radio state, Wi-Fi and Bluetooth power states, and wakelock
-reasons.</p>
-
-<p>Statistics include:</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>System UID aggregated statistics</li>
-</ul>
-
-<p>Use the output of the dumpsys command with the
-<a href="https://github.com/google/battery-historian">Battery Historian</a> tool to generate HTML
-visualizations of power-related events from logs.</p>
