We do not recommend Flash Lite development on current Nokia devices, and all Flash Lite articles on this wiki have been archived. Flash Lite has been removed from all Nokia Asha and recent Series 40 devices and has limited support on Symbian. Specific information for Nokia Belle is available in Flash Lite on Nokia Browser for Symbian. Specific information for OLD Series 40 and Symbian devices is available in the Flash Lite Developers Library.

Flash Lite Code

Code

stop();
var talktime:Number;
 
var standbytime:Number;
device_name_txt = "N95";
 
//Get Instant Battery Check
batteryFunc();
// Monitor Battery level after certain time elapse to 
// call the function to show batter status on the screen.
// Set Interval in miliseconds
setInterval(batteryFunc, 5000); //5 Seconds        
 
//Battery func fetches the battery level and displays it on the screen
function batteryFunc(){
 
batMax = fscommand2("GetMaxBatteryLevel");
batLevel = fscommand2("GetBatteryLevel");
batSource = fscommand2("GetPowerSource");
 
//Change the battery_lvl_mc height depending on the Battery Level
_root.battery_mc.battery_lvl_mc._height = Math.ceil(batLevel*100/batMax);

Determining Battery life and standby time

---

Remaining Battery time and standby time can simply be known by the targeted device specifications. hence using a simple mathematical formula, results can be quickly known

//Show Battery text
//N95 - standard talk time is 6.5 Hours and Standby time is 220 Hours
battery_Txt = "Battery Level: " add Math.ceil(batLevel*100/batMax) add "%";
Talk_time_Txt = Math.round(batLevel*390/batMax) add " mins" ; //N95 6.5 Hours
stand_by_time_Txt = Math.ceil(batLevel*220/batMax) add " hr"; //N95 220 Hours
 
//Change Display status based on battery source
if (batSource == 0) {  //On Battery
	_root.battery_mc.gotoAndStop(2);
}
//Change Display status
else if (batSource == 1) { //On Charger
	_root.battery_mc.gotoAndStop(3);
}
else { //Unknown
	_root.battery_mc.gotoAndStop(1);
}
 
}

device specifications for some of the nokia mobile phones

//Determine Device talk time and standby time based on the Phone Specifications taken from Nokia Website
statusdevice = fscommand2("GetDevice", "devicename");
switch(devicename) {
    case "Nokia N95":
        device_name_txt = "N95";
		talktime =  390; //6.5 hours    
		standbytime = 220; //220 Hours
        break;  
	case "Nokia 5300":
		device_name_txt = "5300";
		talktime =  192; //3.2 hours    
		standbytime = 223; //220 Hours
        break;  
	case "Nokia 6290":
		device_name_txt = "6290";
		talktime =  210; //3.5 hours    
		standbytime = 260; //260 Hours
        break; 
	case "Nokia 6300":
		device_name_txt = "6300";
		talktime =  210; //3.5 hours    
		standbytime = 348; //348 Hours
        break; 
	case "Nokia 7390":
		device_name_txt = "7390";
		talktime =  190; //3 hours    
		standbytime = 220; //220 Hours
        break; 	
	case "Nokia 3250":
		device_name_txt = "3250";
		talktime =  210; //3.5 hours    
		standbytime = 245; //245 Hours
        break; 		
}
