Hi all, I was just wondering whether I was the only one who is experiencing better battery life with 10.4.6. My powerbook is two years old and had a battery life of about 2 hours on a full charge. Now with 10.4.6 it estimates 2 hours 45 minutes. I am letting it run down now at the moment but the estimate seems to be exact... If this is true this is a great present from apple!
