iOS build is much slower than android

Hi

I am developing a game in Unity, the game runs perfect in android but in iOS its really laggy. I move the player right and left with pan gesture there is a huge delay in their movement.

I have set the frame rate to 60 FPS and also the timestep accordingly to .016

Still no improvements. Can any one suggest?

If I make a iOS build with target resolution in 320p (iPhone) there is a huge improvement in the game, but still not comparable to android. I also tried turning on the interpolation for my player and ball as I read on one forum, still nothing!

Please help me out!

Thanks

Are the actual framerates different between them, or is it just input lag?

Also, what actual devices are you using? If you comparing a Galaxy S5 to an iPhone 4, of course the iOS is going to be much slower…

The device I am using is S2 and iPhone4s. The frame rendering is slow, the game is slow as well as the their is 0.5 sec input lag when I move my players.

Can you please suggest what should I check? The difference in performance is huge, the game is not playable on iPhone.

Thanks

Any othrer plugins you using here ? Ads trying to load in the backround ? Video ads caching ?

No, I am not using any other external plugins.
