This code snippet demonstrates how to check the battery level using the SystemInfo Platform Service for Flash Lite, supported from S60 5th Edition onwards.


// Import Platform Service Interface
import com.nokia.lib.Service;
// Heading of the application
heading_txt.text = "Checking Battery level";
// Create a new Service object which has SystemInfo Service data
var sysInfo = new Service("Service.SysInfo", "ISysInfo");
// Define input parameters
var inParams = {Entity:"Battery", Key:"BatteryStrength"};
// Retrieve information about a system attribute with an asynchronous call
// Define callback function
function onReceive(transactionID:Number, eventID:String, outParam:Object) {
if (outParam.ErrorCode == 0) {
var systemData = outParam.ReturnValue;
var batteryStatus = systemData.Status;
text_txt.text = "Battery status: "+batteryStatus+"%";
} else {
var errorId = outParam.ErrorCode;
text_txt.text = "Error: "+errorId;


The battery level of the device is displayed. Battery level is between 0 - 100 percent.

Example application

The following sample application has been tested in Nokia 5800 XpressMusic (S60 5th Edition, Flash Lite 3.0).
