-        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.

-        Using the <a href="#idl-def-BatteryManager" class="idlType"><code>BatteryManager</code></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:

-        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>
-        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:
