PhoneGap/Cordova batter status

The PhoneGap/Cordova framework has 3 events that your application can listen to get battery related information those events are batterystatus, batterylow, batterycritical This is sample code that i have to listen to battery related events

document.addEventListener("deviceready", function(){
  window.addEventListener("batterystatus", function(info){
    console.log("Inside document.addeventlistener -batterystatus ");
    console.log("Battery level " + info.level);
    console.log("isPlugged " + info.isPlugged);
  }, false);
  window.addEventListener("batterylow", function(info){
    console.log("Inside document.addeventlistener -batterylow " );
    console.log("Battery level " + info.level);
    console.log("isPlugged " + info.isPlugged);
  }, false);
  window.addEventListener("batterycritical", function(info){
    console.log("Inside document.addeventlistener -batterycritical " );
    console.log("Battery level " + info.level);
    console.log("isPlugged " + info.isPlugged);
  }, false);
 }, false);

I used the Worklight Mobile browser simulator to test this code, inside my event handler i am reading battery level and if battery is plugged in or not.
