| <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 <package-name></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">Bluetooth, cellular, and Wi-Fi usage</h2> |
| |
| <p>Support for battery usage data on Bluetooth, cellular, and Wi-Fi data |
| requires the device Bluetooth, cellular, and Wif-Fi 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 Bluetooth, cellular |
| (as of Android 7.0), or Wi-Fi radio power data is available from the chipset, it |
| uses chipset data instead of power profile data. For details, see |
| <a href="{@docRoot}devices/tech/power/values.html#values">Power values</a>.</p> |
| |
| <p class="note"><strong>Note</strong>: Prior to Android 6.0, power use for |
| Bluetooth radio, cellular radio, and Wi-Fi 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> |
