Android samsung s4 framerate issues

I’ve created a empty JSB application with nothing but a scene and the framerate moves from 55fps-60fps with nothing on the screen… I’ve tested on other devices an they are a little better in terms of steady framerate(even older devices). I’ve even seen the framerate drop to 40 frames randomly. I’ll take a video if requested but this makes no sense. Is there something wrong with the way I’m building the file? I’ve done it in debug and release mode and it has the same issue. This also happens when I’m running my game and is causing jerky movement of sprites.

some advices for you aimed at improving game performance:

Use SpriteBatchNode if possible,
Review your code, pay special attention to while loop, for… and actions… sprite animation.
Use cc.pool
