Post your manufacturer estimated battery life here

And also say whether it does meet the specs or not during normal use.

My MacBook Air, for example, is rated for 5 hours at 50% brightness under OS X.

Usually, when I use the machine in Windows 7, with brightness set to 6/15 (about equivalent to 70%), it lasts around 3.5 to 4 hours.

What about yours?

Dell says I should be getting up to 5 hours and 15 minutes.

If I try to conserve my battery I can maybe get 3 hours and 15 minutes, otherwise it's usually around 2:45.

edit: It's also amusing what they say about it.

"Increase your mobility with the optional nine-cell battery, with up to 10 hours and 24 minutes of battery life, or choose the standard six-cell battery for up to five hours and 15 minutes of power."

Yeah, like the nine-cell battery will get you ten and a half hours of battery life.

OK, I've done some further testing on my laptop, and it seems that, on 3/15 brightness in Windows 7, with power-saving mode activated on the display (but not on the computer itself), I get 3 hours and 20 minutes before the battery hit 3%. Pretty awful, no?

I've always wondered why no one else seems to be bothered with their laptop battery stats.

Umm... My HP Pavilion fancinessIforgetNames has an estimated battery life of 10 hours, and it lasts that long if you don't do much on it. (like, just playing music from the computer)

My Toshiba Satellite L550-113 should get around 3 hours, but I'm lucky to get over an hour on it. It used to be top-of-the-range... ):

My Toshiba Satellite L750/L755 SHOULD get 3:15 hours. I get around 20 minutes, and that was when it was new
