Batching objects with Instantiate for optimization

Hello, i was trying to instantiate many objects in random positions, but my frame rate didnt seem to like that, so i´ve been trying to optimize it for hours now. I discovered that batching should work, because every object is really the same one, but i can´t get it to work. Here is my code:

     public GameObject candle;
     public int initialSpawn;
 
     [Min(0.0001f)]
     public float velocity;
     public float radius=60;
 
     void Start()
     {
         GameObject[] spawnedCandle = new GameObject[initialSpawn];
         for(int i=0; i< initialSpawn; i++)
         {
             //Sets a random point around this spawner object
             gameObject.transform.Rotate(new Vector3(0, Random.Range(0f, 360f), 0));
             //Creates a candle in that random point
             spawnedCandle[i] = Instantiate(candle, transform.position + transform.forward * Random.Range(0f, radius), Quaternion.identity);
             spawnedCandle[i].transform.Rotate(new Vector3(90, 0, 0));
         }
         for (int i = 0; i < initialSpawn; i++)
             {spawnedCandle[i].transform.parent = transform;}
         
         StaticBatchingUtility.Combine(spawnedCandle, candle);
     }

I dont know if i should use another object as the parent in the StaticBatchingUtility.Combine() function, or im doing something wrong, but draw calls kepp getting to high numbers, instead of just a couple for each different element.

I´m also posting a photo of the result just in case it helps.

I also tried simplyfing the candle object to simply a bowl, wich is 1 mesh and of course 1 material, but still high draw calls.
