Using a larger size print will mean more page turns so the battery will be used up a bit faster as well.
I'd never thought of this one. Mine is certainly on the large size. My battery also on my 2 month old Kindle 3G seems to drop much more rapidly than I would expect. This week, I purposely turned off wireless except for a once-a-day download, and I have not used the browser at all. I'm on day 9, and the battery is quite low. I imagine a charge will be necessary today. I have probably averaged only about an hour of reading each day. I'm not especially worried about it since I'm never away from electricity for long periods of time. I just miss out on the boasting factor.
