Device overheat. Shader problem?

Hello everyone!
I am developing my endless runner game, and my game overheats a device (Sams. Galaxy S3) very fast.
Can't make a screen of stats, here is main info:
Draw calls: 14-20,
Verts: 15k-25k.
All textures are max. 1024x1024 size.
I need a bending effect of environment, so shaders look as follows:
Bending_Diffuse

Code (csharp):

1. Shader "MyShaders/Diffuse_Color" {
2. Properties {
3.   _Color ("Main Color", Color) = (1,1,1,1)
4.   _MainTex ("Texture", 2D) = "white" {}
5.   // _QOffset ("Offset", Vector) = (0,0,0,0)
6.   _Dist ("Distance", Float) = 200.0
7.  
8.   }
9.   SubShader {
10. Tags { "RenderType"="Opaque" }
11. LOD 10
12.   CGPROGRAM
13.   #pragma surface surf Lambert vertex:vert
14.  
15.   struct Input
16.   {
17.   float2 uv_MainTex;
18.   float4 pos : SV_POSITION;
19.   };
20.  
21.   sampler2D _MainTex;
22.   fixed4 _Color;
23.   float4 _QOffset;
24.   fixed _Dist;
25.  
26.   void vert (inout appdata_full v)
27.   {
28. float4 vPos = mul (UNITY_MATRIX_MV, v.vertex);
29.   float zOff = vPos.z/_Dist;
30.   vPos += _QOffset*zOff*zOff;
31.   v.vertex = mul(transpose(UNITY_MATRIX_IT_MV), vPos);
32.   }
33.  
34.  
35.   void surf (Input IN, inout SurfaceOutput o)
36.   {
37. fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color;
38. o.Albedo = c.rgb;
39. o.Alpha = c.a;
40. }
41.   ENDCG
42.   }
43.   Fallback "Diffuse"
44.   }

Bending_DiffuseDetail:

Code (csharp):

1. Shader "MyShaders/Diffuse_Detail_Color" {
2. Properties {
3.   _Color ("Main Color", Color) = (1,1,1,1)
4.   _MainTex ("Texture", 2D) = "white" {}
5.   //_QOffset ("Offset", Vector) = (0,0,0,0)
6.   _Dist ("Distance", Float) = 200.0
7.   _Detail ("Detail (RGB)", 2D) = "gray" {}
8.   }
9.   SubShader {
10. Tags { "RenderType"="Opaque" }
11. LOD 10
12.   CGPROGRAM
13.   #pragma surface surf Lambert vertex:vert
14.  
15.   struct Input
16.   {
17.   float2 uv_MainTex;
18.   float2 uv_Detail;
19.   float4 pos : SV_POSITION;
20.   };
21.  
22.   sampler2D _MainTex;
23.   sampler2D _Detail;
24.   fixed4 _Color;
25.   float4 _QOffset;
26.   fixed _Dist;
27.  
28.   void vert (inout appdata_full v)
29.   {
30. float4 vPos = mul (UNITY_MATRIX_MV, v.vertex);
31.   float zOff = vPos.z/_Dist;
32.   vPos += _QOffset*zOff*zOff;
33.   v.vertex = mul(transpose(UNITY_MATRIX_IT_MV), vPos);
34.   }
35.  
36.  
37.   void surf (Input IN, inout SurfaceOutput o)
38.   {
39. fixed4 c = tex2D(_MainTex, IN.uv_MainTex) * _Color;
40. c.rgb *= tex2D(_Detail,IN.uv_Detail).rgb*2;
41. o.Albedo = c.rgb;
42. o.Alpha = c.a;
43. }
44.   ENDCG
45.   }
46.   Fallback "Diffuse"
47.   }

What do U think, do these shaders look good enough for mobile, or bending effect makes it very complex to display?

 

How do you know the Shader is causing these overheat issues?

 

I am not sure, that shader can be the main reason.
Also I tries to analyze other aspects, like scripts and gameobjects in my game.
Scripts are quite simple and amount of draw calls and verts is very good for mobile.
The game on device runs smooth, but overheats it like from the 1st second, so I decided, that shader can be a reason for this.

 

http://docs.unity3d.com/ScriptReference/Application-targetFrameRate.html

Application.targetFrameRate = 30;

Set that in your Start()

 

wow thanks, gonna check it

 

It's probably because you are using new shaders or some of graphics features which came with Unity5. I had same problem, so i changed back shaders to mobile shaders and turned off GI and all that new fancy graphic features.

 

Actually the frame rate fix does not stop overheating but does help:.With the GUI updates in next Unity update, reduced drawcalls might help
