iOS build lags but is fine on Android

Questions & Answers

I made a simple 2D runner game.
The game runs fine on Android devices, but when I build & run it on iOS, it seems laggy.
The UI and the SoundSystem are ok, but it seems to be a rendering problem.

This is the profiler for Android :

And the profiler for iOS :

Is there any known issue with iOS which could explain this?

I increased the targetFrameRate as a temporary solution.
