Question UI Performance Issue

I've been working on an android game project for about a year. I have overcome many problems in this project and have progressed.

this project is a 2D game and has a somewhat detailed interface and I have a problem with the performance of this interface.

I am using "Sprite Atlas" for every sprites in the interface;

The mobile phone I have "xiaomi red mi note 7" and I get the FPS values from here, and I also feel it while playing.

firstly I thought that the cause of this problem was "setpass calls" and "batches" and I reduced it from 250 levels to 45-44. nothing has changed. "fps" values are the same.

Then I realized that these sprites have high resolution. I've reduced it by almost 4x (the largest right now is about 50kb in size but compressed by krita).
nothing has changed.

Then I opened a different scene and transferred the interfaces that caused loss of performance. I turned off all "scripts". I gained about 5 FPS (from 45 to 50) (i thought its cause "update voids")

"UI" options "render mode" nothing change. and yes the problem seems to be with the "UI".

actually it's still a useful interface, but I don't want to drain the player's battery quickly. otherwise it works perfectly.


now questions:

1. How can I see "setpass calls" and "batches" values from android phone. I don't know if it's really caused by that. I want to test if "sprite atlas" works on my phone.

2. Could this problem be related to "krita" compression? Will another program fix the problem?

3. I could be wrong on the two questions above. If you want a different detail, just write. maybe the problem is different.

 

You can build a development build and attach the profiler. See the docs.

sorry my bad. its about the "UGUI".
