Strange profiling results on Android devices

I'm receiving strange performance profiling results on Android devices. There are no complicated geometry/lighting/effects etc, just simple logical tests. And problem is that I have primary device Meizu MX6 and it shows worse results then less powerful devices. For example MX6 show 18-20 FPS and Samsung J2 Prime shows 30 FPS (they both Mali).

When profiling I see current picture on MX6:



CPU waiting for GPU most of the time - Gfx.WaitForPreset = 70%, and GPU has all covered in RenderForwardOpaque.Render. Quality - very low/v-sync off. Camera - Solid color, no occlusion/hdr/msaa. Can you suggest problem/decision? Will provide any additional required information.
