Optimus IV 15.6" vs 17.3"

[sirbb]

Apart from size, weight, screen size and webcam, as far as I can tell the Optimus IV 15.6" is the same as the Optimus 17.3". Would anyone know what the difference in battery life is between the two if they have the same processors, hard drive etc. etc. and are running the same tasks side by side?

Thank you!

Have seen some vids on youtube (at work so can't post links) that suggest the 15.6 (AKA Clevo W350ETQ) slightly out-performs its larger counterpart but the differences are marginal...
