Took 3-3.5 hours to run down a battery on a New iBook 14" two weeks ago running a DV the whole time to see how long it would last. New Powerbooks are supposed to have better batteries than the previous ones (from yesterday), but nothing to compare with. Will let you know when my new 15" is delivered in a few days.kimchimonkey said:I'm trying to decide between a ibook and a powerbook. I don't mind the price, but how do they compare in terms of battery life. Listing saids 5 for the powerbook 12" and 6 for ibook. Anyone with real world experience?
