Most new devices need a few charge cycles before they reach maximum capacity..
Also, manufacturers like to exaggerate battery life.. Its probably 7 hours in test conditions
No with the batteries in the Macbooks the claims are just about spot on. All the reviews I have read say the 7 hours is achievable, with some reviews getting even more depending on usage.
yes 7 hours is meant to be achievable... The battery still lasts long enough though, about 4 and a half hours yesterday. I only got it yesterday, so ill see if it gets better after the first few charges
Depends on a few things - do you have WiFi on? Bluetooth on? keyboard backlight on?
All those things will seriously reduce the estimated battery life from the full 7 hours to around about 5 hours.
Try turning absolutely everything off and turn your brightness down to about 40% then you'll be seeing the type of battery life that Apple have claimed and it'll be the type of usage that they claim is required to achieve it too.

So I've had my laptop for about 5 days now, I haven't really been using it with the better battery life selected as I've been playing crysis while running windows. But a few days ago I got about 4 and a half hours with backlight about 70% and full keyboard brightness and wifi on, Bluetooth off
I get about 5 hours of solid usage with most things running like WiFi, full brightness (for around 75% of the time then i lower it), lots of applications and movies/music running. I get up to 7 hours if i limit what I do
