Using lower precision for some operations can speed up the math involved (at the cost of, of course, less precision).

This is rarely needed in the vertex shader (where full precision is needed most of the time), but often needed in the fragment one.

Please read the relevant documentation on the target architecture to find out more. In all honesty though, mobile drivers are really buggy
|

so just stay out of trouble and make simple shaders without specifying precission unless you *really* need to.
