I've got the newest 15 inch mpb. On a full charge I only get about 3-4 hours of battery life when simply browsing the web, sometimes even less! Is this normal? I recall reading that these models should get around 7 hours...I wish!
 
it depends on the brightness of your screen and whether the sites you visit use a lot of Flash.

I have a 13. With brightness at 30% and not a lot of flash I get 5.30-6.00 hours of browsing - chatting

So when apple gives statistics for the battery life are they assuming you have brightness lowered?

Well...yes, probably. Is that really unreasonable? They say up to 7 hours, not 'up to 7 hours at full tilt'.

They also assume you aren't running the CPU at 100% all the time, but you wouldn't complain about that, would you?
 
Yeah I have a mbp 13 and I maybe get around 3 hrs whn browsing at about 60% brightness. The whole 7 hour batter life is bs when u have to have te screen at 10% brightness and no backlit keyboard

I really dont know how. My late 2007 BlackBook can still get over 5 hours on around 40% brightness.

Heh, fair enough.

If you have a dig around on the Apple site, there's some small print saying something along the lines of browsing and using office applications with wireless networking turned on and the screen set to 50% brightness.
 
If you are on websites with flash (most sites got some sort of flash-ad) the battery will die pretty quick. Try downloading "Clicktoflash" for safari. It's gold when surfing around. Plus that it will allow you to watch youtube in h264 with quicktime instead of flash ;)
 
Thanks guys! I was I was gullible to believe that when they said 7 hours it meant with with my keyboard bright, running programs, and with the keyboard lit ha. I guess it makes sense that this isnt the case. Thanks for the clarifications.

Yea, I figured a 7 hour battery was too good to be true. I was a bit aggravated when I found that my battery didn't last more than 5 hours (80% brightness and no bluetooth).
