+ The functionality described in this specification was initially
+ specified as part of the
+ <a href="http://www.w3.org/TR/system-info-api/">System Information
+ API</a> but has been extracted in order to be more readily available,

+ <section class="informative">
+ <h2>Introduction</h2>
+ <p>
+ The Battery Status API specification defines a means for web
+ developers to programmatically determine the battery status of the
+ hosting device. Without knowing the battery status of a device, a web
+ developer must design the web application with an assumption of
+ sufficient battery level for the task at hand. This means the battery
+ of a device may exhaust faster than desired because web developers are
+ unable to make decisions based on the battery status. Given knowledge
+ of the battery status, web developers are able to craft web content and
+ applications which are power-efficient, thereby leading to improved
+ user experience.
+ </p>
+ <p>
+ The Battery Status API can be used to defer or scale back work when
+ the device is not charging in or is low on battery. An archetype of an
+ advanced web application, a web-based email client, may check the
+ server for new email every few seconds if the device is charging,
+ but do so less frequently if the device is not charging or is low on
+ battery. Another example is a web-based word processor which could
+ monitor the battery level and save changes before the battery runs
+ out to prevent data loss.
+ </p>
+ <p>
+ The following example shows how a web-based email client could check
+ for new emails every ten seconds without knowledge of the battery
+ status:
+ </p>
+ <pre class="example sh_javascript">
+ <!DOCTYPE html>
+ <html>
+ <head>
+ <title>Email Client</title>
+ <script>
+ var mail = {
+ INTERVAL_DEFAULT: 1000 * 10,
+ interval: null,
+ timer: 0,
+
+ check: function () {
+ console.log('Checking the server for new emails using an interval of ' +
+ (mail.interval / 1000) + ' seconds.');
+ },
+
+ setTimer: function (interval) {
+ if (interval === mail.interval) { return; }
+ if (mail.timer !== 0) { clearTimeout(mail.timer); }
+ if (interval) { mail.timer = setInterval(function () { mail.check(); }, interval); }
+ mail.interval = interval;
+ }
+ };
+
+ window.addEventListener('load', function () {
+ mail.setTimer(!mail.interval ? mail.INTERVAL_DEFAULT : mail.interval);
+ }, false);
+ </script>
+ </head>
+ <body></body>
+ </html>
+
+ </pre>
+ <p>
+ The script will always check for emails every ten seconds, even if the
+ battery level is critically low and the device is not charging.
+ This is an example of poor resource management.
+ </p>
+ <p>
+ Using the <a>BatteryManager</a> interface, the web application is, for
+ example, able to throttle checking for emails if the device is low on
+ battery, stop checking for emails if the battery is critically low and
+ resume normal operation when the battery is charging:
+ </p>
+ <pre class="example sh_javascript">
+ <!DOCTYPE html>
+ <html>
+ <head>
+ <title>Battery-aware Email Client</title>
+ <script>
+ var mail = {
+ INTERVAL_BATTERY_LOW: 1000 * 60 * 10,
+ INTERVAL_DEFAULT: 1000 * 10,
+ interval: null,
+ timer: 0,
+
+ check: function () {
+ console.log('Checking the server for new emails using an interval of ' +
+ (mail.interval / 1000) + ' seconds.');
+ },
+
+ setTimer: function (interval) {
+ if (interval === mail.interval) { return; }
+ if (mail.timer !== 0) { clearTimeout(mail.timer); }
+ if (interval) { mail.timer = setInterval(function () { mail.check(); }, interval); }
+ mail.interval = interval;
+ }
+ };

+ <p>
+ This specification defines conformance criteria that apply to a single
+ product: the <dfn>user agent</dfn> that implements the
+ interfaces that it contains.
+ </p>
+ <p>
+ Implementations that use ECMAScript to implement the APIs defined in
+ this specification must implement them in a manner consistent with the
+ ECMAScript Bindings defined in the Web IDL specification [[!WEBIDL]],
+ as this specification uses that specification and terminology.
+ </p>
+ </section>
+ <section>
+ <h2>Terminology</h2>
+ <p>
+ The <code><a href="http://dev.w3.org/html5/spec/webappapis.html#eventhandler">
+ EventHandler</a></code> interface represents a callback used for event
+ handlers as defined in [[!HTML5]].
+ </p>
+ <p>
+ The concepts <dfn><a href="http://dev.w3.org/html5/spec/webappapis.html#queue-a-task">
+ queue a task</a></dfn> and
+ <dfn><a href="http://dev.w3.org/html5/spec/webappapis.html#fire-a-simple-event">
+ fires a simple event</a></dfn> are defined in [[!HTML5]].
+ </p>
+ <p>
+ The terms <dfn><a href="http://dev.w3.org/html5/spec/webappapis.html#event-handlers">
+ event handlers</a></dfn> and
+ <dfn><a href="http://dev.w3.org/html5/spec/webappapis.html#event-handler-event-type">
+ event handler event types</a></dfn> are defined in [[!HTML5]].
+ </p>
+ </section>
+ <section>
+ <h2>Security and privacy considerations</h2>
+ <p>
+ The API defined in this specification is used to determine the battery
+ status of the hosting device. The information disclosed has minimal
+ impact on privacy or fingerprinting, and therefore is exposed without
+ permission grants. For example, authors cannot directly know if there
+ is a battery or not in the hosting device.
+ </p>
+ </section>
+ <section>
+ <h2><a>NavigatorBattery</a> Interface</h2>
+ <p>
+ The <a>NavigatorBattery</a> interface is exposed on the
+ <code>Navigator</code> object.

+ When a <code>BatteryManager</code> object is created,
+ <code>charging</code> MUST be set to true, <code>chargingTime</code>
+ to 0, <code>level</code> to 1.0 and <code>dischargingTime</code> to
+ the value positive Infinity, if the implementation is unable to report
+ the battery's charging state, charging time, level or remaining time
+ respectively.
+ </p>
+ <p>
+ The <code>charging</code> attribute MUST be set to false if the battery
+ is discharging, and set to true, if the battery is charging, the
+ implementation is unable to report the state, or there is no battery
+ attached to the system, or otherwise. When the battery charging state
+ is updated, the <a>user agent</a> MUST <a>queue a task</a> which sets
+ the <code>charging</code> attribute's value and <a>fires a simple
+ event</a> named <code><a>chargingchange</a></code> at the
+ <a>BatteryManager</a> object.
+ </p>
+ <p>
+ The <code>chargingTime</code> attribute MUST be set to 0, if the
+ battery is full or there is no battery attached to the system, and to
+ the value positive Infinity if the battery is discharging, the
+ implementation is unable to report the remaining charging time, or
+ otherwise. When the battery charging time is updated, the <a>user
+ agent</a> MUST <a>queue a task</a> which sets the
+ <code>chargingTime</code> attribute's value and <a>fires a simple
+ event</a> named <code><a>chargingtimechange</a></code> at the
+ <a>BatteryManager</a> object.
+ </p>
+ <p>
+ The <code>dischargingTime</code> attribute MUST be set to the value
+ positive Infinity, if the battery is charging, the implementation is
+ unable to report the remaining discharging time, there is no battery
+ attached to the system, or otherwise. When the battery discharging time
+ is updated, the <a>user agent</a> MUST <a>queue a task</a> which sets
+ the <code>dischargingTime</code> attribute's value and <a>fires a
+ simple event </a> named <code><a>dischargingtimechange</a></code> at the
+ <a>BatteryManager</a> object.
+ </p>
+ <p>
+ The <code>level</code> attribute MUST be set to 0 if the system's
+ battery is depleted and the system is about to be suspended, and to
+ 1.0 if the battery is full, the implementation is unable to report the
+ battery's level, or there is no battery attached to the system. When
+ the battery level is updated, the <a>user agent</a> MUST <a>queue a
+ task</a> which sets the <code>level</code> attribute's value and
+ <a>fires a simple event</a> named <code><a>levelchange</a></code> at
+ the <a>BatteryManager</a> object.

+ <div class="note">
+ The definition of how often the <code><a>chargingtimechange</a></code>,
+ <code><a>dischargingtimechange</a></code>, and <code><a>levelchange</a>
+ </code> events are fired is left to the implementation.
+ </div>
+ <section>
+ <h2>Event handlers</h2>
+ <p>
+ The following are the <a>event handlers</a> (and their corresponding
+ <a>event handler event types</a>) that MUST be supported as
+ attributes by the <a>BatteryManager</a> object:
+ </p>
+ <table class="simple">
+ <thead>
+ <tr>
+ <th>event handler</th>
+ <th>event handler event type</th>

+ <h2>Examples</h2>
+ <p>
+ This trivial example writes the battery level to the console each time
+ the level changes:
+ </p>
+ <pre class="example sh_javascript">
+ navigator.battery.onlevelchange = function () {
+ console.log(navigator.battery.level);
+ };
+ </pre>
+ <p>
+ Alternatively, the same using the <code>addEventListener()</code>
+ method:
+ </p>
+ <pre class="example sh_javascript">
+ navigator.battery.addEventListener('levelchange', function () {
+ console.log(navigator.battery.level);
+ }, false);
+ </pre>

+ <h2>Acknowledgements</h2>
+ <p>
+ The group is deeply indebted to Mounir Lamouri, Jonas Sicking, and
+ the Mozilla WebAPI team in general for their invaluable feedback
+ based on prototype implementations. Many thanks to the people behind
+ the System Information API and Device Orientation Event specification
+ for the initial inspiration. Also thanks to the nice folks bringing us
+ the Page Visibility specification, which motivated the editor of this
+ specification to write the introduction chapter discussing some
+ real-world high value use cases that apply equally to this
+ specification. Special thanks to all the participants of the Device
+ APIs Working Group and others who have sent in substantial feedback
+ and comments, and made the Web a better place for everyone by
+ doing so.
