Android performance problem

Hi, ive an very strange problem. Im programming an 2d Game for mobile platforms. As im processing further my application has an horrible performance, but only on my android device (PC is perfect) and i dont know what to do about it.
Atm we have an surface with box collider with an friction of 0. Then there are Objects(prefabs) with rigidbody2d that slide onto it. These Objects have an script that looks for the velocity and applys a force if its under an value. It also handels touch commands (problem occurs even if there is no input). These objects stutter and feel extremely laggy on my Samsung S4. On the normal PC, this effect is not visible with fps over 2k.
We instanciate an Object every Second and destroy an other every second too. There are not more than 10 Objecte present at any time.
The prefab has an normal Sprite Renderer attached to it (Sprites-Default material), Rigidbody2D with Interpolate turned on and Mode= Continous.

Some data at peek:
Draw Calls:7
Tris:38 Verts:84
Used Textures: 8 - 2.6MB
I think this is very low.

Weve done the following:
Set almost everything on static
Change Texture Size to 512 and to compressed
Optimze Mesh Data (but we only use some sprites anyway)
Change Physics from continous to discrete
Instanciate 500 of our Objects and deactivate them. Later we only activate it instead of instanciate and we dont destroy them, we only deactivate it.
Set resolution on Phone from FullHD to 300:200
Keep almost all out of Update() and move to FixexUpdate

As far nothing helped. Does anybody has an idea? I think there is somthing im missing. I dont have pro, so there is no profiler. But an monitor app on my s4 showed my app used peak only 20% CPU on my device, so this is not the limiting factor

Thanks for everybody reading my huge post and wants to help,

Did you try Unity profiler?

 

Hi, thank you for your answer. We dont have pro so there is no profiler. Im at my and of knowledge, because theoretically everything should run fine, but i doesnt :-(.. does anyone have an idea? Ive written a simple algorithm that shows time that the script takes to run. Sometimes this shows some microseconds, sometimes incredible times like a minute or so. Commenting out that parts of script does not help..
Greetings

 

There is till a basic profiler. You turn on development build turn on enable internal profiler and watch through logcat. it will give numbers that MAY help you

 

Hi, thank you for your tip! I didnt know that. I'll check that and will post here, if i have found an solution. Thx!!!!

 

Ok, now i took a look at the internal profiler. Thats what it showed me at the moment a lag occurs:

Code (CSharp):

1.  
2. Unity(29312): Android Unity internal profiler stats:
3. Unity(29312): cpu-player>    min:  4.1   [B]max: 557.1[/B]   avg: 26.8

5. Unity(29312): cpu-present>   min: -16.8   max:  0.2   avg: -0.7
6. Unity(29312): frametime>     min:  4.5   [B]max: 557.5[/B]   avg: 26.4

13.  

As im guessing, it seems to be a cpu-problem not related to fixedUpdate or Update. Hm i have to rethink my code. This tip was great, thanks Kilrath81!!

yea im guessing that 557.1 spike likely not good
