What is the difference in battery life between 14 and 15 inch laptops?

[Bruno Vincent]

I searched all over the internet, but can't find any research on that....

Many notebooks have 2 identical models, same specs but one is 14 and one is 15, same battery also, same w/hour, cpu, ram, all of it.

What percentage difference will there be between 14 and 15.6 , same usage, same benchmarks.

There MUST be some research and benchmarks on this?

Should not be too much difference if the only thing different is screen size. The extra inch or so of backlight won't use that much power. You can pick a faster car that can hit 150 vs 145 mph for another one, but really that difference is nothing if you are giving up something like a back seat some other nice feature.
