Tiled sprite performance on mobile

Hi
i am using this asset from asset store : https://www.assetstore.unity3d.com/en/#!/content/23091​

it works nice but there is a problem. Each tile has it's own sprite renderer and 2d collider types. Lets create 64x64 tile grid this equals 4096, assume 50% of tiles are air, so we have 2048 sprite renderers and 2d colliders. Also we need foreground and background layers for only decorations 3*2048 = 6144 sprite renderer. At the end we have 6144 renderer and 2048 2d colliders. Does it make any performance impact on last 3 generation mobile devices ?
