Hello,

You can get it using systeminfo api as following.

  var id = null;
   function onSuccessCallback(battery) {
                  console.log("Battery level is " + battery.level); 
  }

  id = tizen.systeminfo.addPropertyValueChangeListener("BATTERY", onSuccessCallback);

and you can find more information about systeminfo api on help page of IDE.

Hello

Please refer the sample code in the DigitalWatch. This code is checking the battery status.

var battery = navigator.battery || navigator.webkitBattery || navigator.mozBattery;

battery.addEventListener('chargingchange', getBatteryState);
battery.addEventListener('chargingtimechange', getBatteryState);
battery.addEventListener('dischargingtimechange', getBatteryState);
battery.addEventListener('levelchange', getBatteryState);

function getBatteryState() {
    var battery_level = Math.floor(battery.level * 100);
    
    // TODO
}
