14" v. 15" battery life?

[Kenn]

Any noticeable differences? I don't mind going 15" for the robust construction, extra readability, and IPS display, but if it takes more than 10-20 minutes off of a 4hr charge I might swing back to the 14" instead.

The 15" display does draw more power than the 14.1". Exact specs are on several older threads.

I get 3.5 hours out of my 15" UXGA with contrast on low and aggressive power saving on (but with wireless on as well). I think the norm for 14" is a little over 4 hours.

Thanks! Could I trouble you to point me to the thread (or give me an indication of what terms I should search for)?
