 if (battery) {
 var batteryLevel = Math.round(battery.level * 100) + "%",
 charging = (battery.charging)? "" : "not ",
 chargingTime = parseInt(battery.chargingTime / 60, 10),

 battery.addEventListener("dischargingtimechange", setStatus, false); }
  25. 25. VIBRATION API
  26. 26. VIBRATION API // Vibrate for one second
 navigator.vibrate(1000);
 
 // Vibration pattern [vibrationTime, pause,…]
 navigator.vibrate([200, 100, 200, 100]);
 
 // Vibrate for 5 seconds
 navigator.vibrate(5000);
 
 // Turn off vibration
 navigator.vibrate(0);
  27. 27. NETWORK INFORMATION API
