iOS device performance problem

Hello,

I have a simple 2D game made in Unity. It works perfectly on all Android devices. Recently I've made a decision to develop it for iOS also. When I try that same game on iOS device, it performs quite badly. It is not as smooth as on Android devices. It feels like it produces lower fps. Any ideas or tips how to fix this ?

Regards, L


EDIT: I found a problem. By default, iOS devices run on 30 fps, and Android on 60 fps. Is there any way for me to set frame rate to 60 on iOS devices ?...
