My HTML5 web application utilizes hardware acceleration through the CSS3 property translateZ(0).
Everything runs smoothly on my 4s device.
However, when I try the same application on an iPhone4, the performance drastically decreases and becomes almost unusable.

What are the key strategies for optimizing CSS3 transition performance on mobile devices?
Switching from using translateZ(0) with left:x to translate3d(x, y, z) significantly improved the smoothness of all transitions, even on older iPhone models.
