As far as I am concerned the Mac Genius (??) is merely spouting the company line. I am not using heavy graphics. That's a far cry from the promised 8-9 hours, and the excuses sound like weasel-wording to me. I have been cheated, and so have you who sit back and accept the excuses. Promises were not kept. Either that, or Apple is guilty of false advertising. All 1--800-SOSAPPLE to complain loud and long.

The tech said that my 17" i5 was running perfectly but that the 8-9 hour battery life is based on the monitor at half brightness and 1 or 2 simple tasks, such as emailing. That probably does't include Safari. Sucks!!! Ain't that speciall?!!!!!. EEEeeeeeeeerrrrRRRRRRRRR!!! Just got back from the 'genius bar' at the Apple store.

I own a 17" uMBP with 7200rpm HHD. The computer was manufactured in November 2009, and I have gotten a few minutes over 9 hours out of the battery life, after a full calibration, running 50-75% brightness on the screen, depending on the light around me. I also ran the keyboard between 25-50% brightness. I was doing little more than websurfing (wireless), text editing, and organizing folders, and transferring some items to and from my other computers (wireless). <br>With my average use, I usually get 4-5 hours out of the battery, but that includes playing online games and editing photos & video.

In addition to safari being open, I also had photoshop (small screen rez file) and dreamweaver open. I am a bit disappointed but not surprised. Glad to see that I am not the only person with the same issue. The battery's red warning light on my 17″ i5 popped on after surfing the internet after only 4 hours at most.

When running on the integrated graphics, I'm easily seeing 6 to 9 hours (and even saw 11.5 hours when running just Safari) on my 15″ i7 MacBook Pro.
