Source: How to get current battery life on mobile device - Questions & Answers - Unity Discussions

UIDevice device = UIDevice.CurrentDevice();
device.batteryMonitoringEnabled = true; // need to enable this first
Debug.Log("Battery state: " + device.batteryState);
Debug.Log("Battery level: " + device.batteryLevel);

Search before asking. This prevents duplicate threads.

      public static float GetBatteryLevel()

            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)

                                        {

                                            // Error checking that probably isn't needed but I added just in case.
                                            if (level == -1 || scale == -1)
                                            {
                                                return 50f;

I take you were trolling?
Obviously those libs aren’t even there…

Alright, 5 years later we finally got a concrete solution.

Since Unity 2018.1, you can now get battery level by calling SystemInfo.batteryLevel

This is the function I used to get the complete status of the Battery:

public void UpdateBatteryStatus()
        {
            if(SystemInfo.batteryStatus == BatteryStatus.Charging)
            {
                //Do Something
            }
            else if(SystemInfo.batteryStatus == BatteryStatus.Full || SystemInfo.batteryLevel >= 0.9f)
            {
                //Do Something
            }
            else if (SystemInfo.batteryLevel >= 0.61f && SystemInfo.batteryLevel < 0.9f)
            {
                //Do Something
            }
            else if (SystemInfo.batteryLevel >= 0.51f && SystemInfo.batteryLevel < 0.61f)
            {
                //Do Something
            }
            else if (SystemInfo.batteryLevel >= 0.31f && SystemInfo.batteryLevel < 0.51f)
            {
                //Do Something
            }
            else if (SystemInfo.batteryLevel >= 0.11f && SystemInfo.batteryLevel < 0.31f)
            {
                //Do Something
            }
            else if (SystemInfo.batteryLevel < 0.11f)
            {
                //Do Something
            }
        }
