I've seen that but $$anonymous$$e is already set to "Don't Sync" yet I keep getting that.

Is it getting overridden by your quality settings somehow?

No, I checked it. I don't know what it is but it's eating up all my cpu power especially on mobile.

This worked for me.

To remove the spike in your profiler lower your target framerate using something like:

Application.targetFrameEate = 60;

or

Application.targetFrameEate = 30;

Also have vsync disabled in quality settings.

On mobile, the max framerate is 60fps, so if your game is running faster than that in the editor Gfx.waitforpresent can show a big hit in the profiler while it trys to slow down. Strange though that explicitly setting it lower makes the spike disappear, but I can guarantee this works on my end.

Hey buddy, thanks for the rare answer, after a little bit of research I also found out that these spikes are caused by high frame rate.

Edit : If doing so doesn't get rid of those spikes then you probably have issues with rendering. So it's related to gpu, just like the issue I'm currently having. I'll update my comment once I find a solution.
