Dumb batteries
There's something messed up with the battery calibration system in the Powerbooks. Yesterday, yanking the cord on a fully charged / calibrated battery give 3:12 remaining. I was up on battery power late last night, and when I recharged today, I got 2:41. That's definitely not right, and a far cry from the 4-4.5 hrs advertised. Apple really needs to get going on this, since the new Centrino laptops easily go for 5 hours on a charge, and some go longer (not to mention the fact that they are faster and cooler). I hope that they are doing some serious talking to IBM about power efficient 970's. Either that or Mac OS X on Intel. In the meantime, if there is anybody out there who knows how to whack Powerbook batteries, well, the comment form is below.

I get about 2.5/3 hours from my 12" PB and interestingly enough this has been much more consistent after installing Panther. iBooks report 4-5 hours, but I don't know anybody with a PowerBook that gets much more than 3. I've read on the Apple website that it's good to cycle the battery once a while (full charge to letting it drop to sleep with no juice left), for calibation purposes.

When on battery-power, turn the screen brightness as far down as you can. This can give you significantly more battery life.

Charles,
Thanks for the tip -- I'll turn the keyboard down/off too.
