This is absolutely not the thing I want to find ))) in 8 min of video review took part only 2 min approx. and ... this is not this. (I must admit thar Macbook was 1.3 - that's the only bingo in this video)
Are you doing all the things that they tend to do in those battery tests, usually written in tiny fine print? Things like setting the display to around 75% brightness or less, turning off wifi and Bluetooth, turning off keyboard backlighting etc... For example, if you're working solidly using Lightroom and photoshop like you would do in a normal day's work, with the display at max brightness, then this is a very different use case to the advertised "9 hours of iTunes movie playback" or whatever it is. Any apps that regularly ask the CPU to ramp up will draw significantly more power than usage where the computer is next to idle, more or less. I've seen most people saying that if they use the machine at full tilt (pushing it with CPU intensive tasks with everything switched on and full screen brightness), they mostly report around 4 hours at best.
That said, I have read around the place that some people have been getting noticeably poor battery duration, even when testing out a very basic use scenario following all the low-consumption guidelines. I've also heard that laptop batteries these days have to "settle" after a few rounds of charges before they really deliver their peak performance. But if none of this is working for you, then maybe you got shipped a dud and you should see about getting a replacement. Let us know how you go and how helpful they are with recognising the problem if indeed it is a fault.. I really hope this doesn't happen to me when mine gets delivered, would hate to have to go through a return. Also I've found that the apple geniuses here in France can tend to give you a bit of attitude (basically acting like you don't know what you're talking about and if there's a problem, it's your fault), so I really really hope I won't have to deal with that particular nightmare! Good luck..
Thanks for the reply. Yeah i'm just talking about browsing and emails at 75% brightness. Not sure the exact tests apple does but id LOVE to try it on my computer. Last night I did an old school "calibration" hoping this would help. So many mixed reviews on proper battery maintenance (even from apple) that i wasn't sure. Last night was the first time i let the battery completely run down. I charged fully and now I am seeing a more promising battery "estimate" but still below the advertised 9-10 hours at 75% brightness and browsing. My estimate is 6.5hours. But it fluctuates. Not sure what people consider "light" usage? I am assuming it still involves actively using the computer for the entire time right?
As for "APPLE-TUDE" - the combination of French and Apple "genius" is truly a recipe for arrogant DOUCHiness. HAHAHA
To be fair to the OP, I think people might be misunderstanding what was meant by the use of the word "professional" in this context. English isn't the first language of everyone here, so sometimes subtleties of expression can be a bit off the mark. I think what was meant was that of all the "official" published reviews by all of the major tech press (be it blogs, magazines, tech/computing sites etc), they've almost always worked hands on with a base model machine and have made all of their meaningful assessments based on that. I think the OP was hoping for someone like Anandtech or Ars Technica perhaps, to actually put a 1.3 Ghz machine through its paces and give us the lowdown on what they think. As opposed to the only real opinion floating around on this model coming just from ostensibly more unbalanced sources, i.e., people who bought one..
