Different mobile phones run different FPS. Has anyone done anything in JS to detect the relative speed of the device? I have seem some JS which just loops for a few MS to see if its an iphone 3 (very slow)or iphone 4 for example.
Obviously I can use the System-> Is on mobile device, but this doesnt tell me if if Im running say ipad3 (which is very fast) or an ipad 1 (which I need to no do some animations etc.)
I could just do a loop a 100 times and see how long it took, but you never know what the phone is currently doing.
I use the browser string to see if its an iphone or ipad at least, but you cant do much more than that.
