Display battery level in game?

Unity Engine

Is there a way to get an iPhone/iPod/iPad’s current battery level and display it inside a game in Unity?

I’ve seen quite a few people on forums say it would be useful to be able to access the battery level and time when playing a game (e.g. in a pause menu).

Oh yes, it’s totally possible. You just need an xcode plugin though.

Here’s a Unity Package:

Just call BatteryLevel.GetBatteryLevel (). This will return a number ranging from 0.0 to 1.0.

But you have to add the BatteryLevel.mm script into the xcode project though.

is there an android method for this

  public static float GetBatteryLevel()
    {
        #if UNITY_IOS
        UIDevice device = UIDevice.CurrentDevice();
        device.batteryMonitoringEnabled = true; // need to enable this first
        Debug.Log("Battery state: " + device.batteryState);
        Debug.Log("Battery level: " + device.batteryLevel);
        return device.batteryLevel*100;
        #elif UNITY_ANDROID

        if (Application.platform == RuntimePlatform.Android)
        {
            try
            {
                using (AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
                {
                    if (null != unityPlayer)
                    {
                        using (AndroidJavaObject currActivity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity"))
                        {
                            if (null != currActivity)
                            {
                                using (AndroidJavaObject intentFilter = new AndroidJavaObject("android.content.IntentFilter", new object[]{ "android.intent.action.BATTERY_CHANGED" }))
                                {
                                    using (AndroidJavaObject batteryIntent = currActivity.Call<AndroidJavaObject>("registerReceiver", new object[]{null,intentFilter}))
                                    {
                                        int level = batteryIntent.Call<int>("getIntExtra", new object[]{"level",-1});
                                        int scale = batteryIntent.Call<int>("getIntExtra", new object[]{"scale",-1});

                                        // Error checking that probably isn't needed but I added just in case.
                                        if (level == -1 || scale == -1)
                                        {
                                            return 50f;
                                        }
                                        return ((float)level / (float)scale) * 100.0f;
                                    }
                               
                                }
                            }
                        }
                    }
                }
            } catch (System.Exception ex)
            {
             
            }
        }
      
        return 100;
        #endif
