I actually replicated the CR Battery Test 4 separate times from full battery to shut off (using Battery Logger). I consistently got between 7 and 8 hours. So I doubt CR's claims. But how did you test? Have you at least tried your looping movie suggestion? What were your actual timings?
I haven't tested (waiting on a replacement). I was just pointing out that it seems like a big waste of time/energy for people to be reporting and complaining about non-standardized/non-scientific results.
One person reports they get 14hrs based on their usage pattern, and another person gets worked up and upset because they get 5hrs based on a totally different usage pattern.
You managed to replicate CR's tests? Did you have a local server cache some sites and then cycle through them or something to that effect?
IMHO, when it comes to web-browsing power usage the following variables probably matter:
-the browser
-the list of sites used to test
-the ads which show up on each
-whether or not an ad blocker is used
(Thats one reason I prefer the iTunes movie playback test as it's a bit more standard with minor variations depending on the codec,etc)
Cheers
ps>> i'D imagine that having FileVault, TimeMachine, etc...turned on would impact results.

"Might I suggest, for consistency, people try the looping iTunes movie test (with the configuration(wifi,brightness,etc) for said test, as listed on Apple's website)?
