What is average battery life forAl PowerBook 15" 1.25GHz?

Message #1 - Posted 2003/12/15 - David R Underwood

Hi,
I'm thinking of buying a new PowerBook. I'm checking with everyone here to see if anyone can report their average battery life for a 15" 1.25GHz Aluminum PowerBook (the new model). I've heard people say they get 2-2.5 hours of battery life with OS 10.2.8 but I've also heard of problems with 10.2.8. I'm hoping someone with OS 10.3 (Panther) can give me their average battery life experience. I'm getting 3:20 on a Dell Inspiron 8600 with Speedstep off so I'm looking to get at least that much out of the PowerBook if I go with it. Thanks & have a Merry Christmas!

Panther - 15" PowerBook 1.25Ghz. 2 - 2.25 hours without trying to conserve and nearly 3 when I try to conserve energy

My battery-life isn't much different from 10.2.8 to 10.3. I got a bit over two hours each way. However, today Apple released a battery-updater utility which may improve this.

After upgrading my 1.25GHz Albook to 10.3.2 and the new battery software, I now get a solid 4.5 hours with every possible energy savings enabled (processor, HD, sound, Bluetooth and Airport disabled, screen on mimimum brightness). It's not exactly a realistic use of the Powerbook, but it does, for once, agree with Apple's claims on battery life. Ciao,

Renaud
