/**
 * <p>BatteryService monitors the charging status, and charge level of the device

 * to all {@link android.content.BroadcastReceiver IntentReceivers} that are
 * watching the {@link android.content.Intent#ACTION_BATTERY_CHANGED
 * BATTERY_CHANGED} action.</p>
 * <p>The new values are stored in the Intent data and can be retrieved by
 * calling {@link android.content.Intent#getExtra Intent.getExtra} with the
 * following keys:</p>
 * <p>&quot;scale&quot; - int, the maximum value for the charge level</p>
 * <p>&quot;level&quot; - int, charge level, from 0 through &quot;scale&quot; inclusive</p>
 * <p>&quot;status&quot; - String, the current charging status.<br />
 * <p>&quot;health&quot; - String, the current battery health.<br />
 * <p>&quot;present&quot; - boolean, true if the battery is present<br />
 * <p>&quot;icon-small&quot; - int, suggested small icon to use for this state</p>
 * <p>&quot;plugged&quot; - int, 0 if the device is not plugged in; 1 if plugged
 * into an AC power adapter; 2 if plugged in via USB.</p>
 * <p>&quot;voltage&quot; - int, current battery voltage in millivolts</p>
 * <p>&quot;temperature&quot; - int, current battery temperature in tenths of
 * a degree Centigrade</p>
 * <p>&quot;technology&quot; - String, the type of battery installed, e.g. "Li-ion"</p>
