13-Inch 2013 MacBook Air Gets Up to 15 Hours of Battery Life With Mavericks

15 Hours?! Well, in my real life test of my battery on a macbook air 2013 i7 8meg 500gb hd, I managed to get just little over 9 hours doing:

1. Heavy text editing
2. email
3. texting through messages.
4. converted about 3 gigs of video. Did not really want to do that, I just opened some video files that required some converting by quick time since I upgraded.
5. Web surfing, flash installed but disabled using an extension.
6. voice dictation for about 20 minutes.
7. accessed iPhoto few times: imported photos, deleted and organized photos for about 30 minutes total.
8. used iMovie 6.x to export a short video clip. (5 minutes)

Given the way I use my computer, I really have not noticed a huge or any difference between 10.8 and 10.9, nevertheless, I love the new OS and I believe that my computer is actually faster now. It feels as if apple designed MBA 2013 to work with 10.9 and not it's predecessor.
 
My first cycle after the update on a 2013 MBA was a little worse at first - obviously doing a lot of re-indexing, etc. By the last 25%, it was already showing improvement over ML. The second cycle literally showed 20 hours remaining for for the first five minutes or so while browsing in Chrome. Never thought I'd see that on a laptop...

I read his comment, which is why I posted the comment in the first place. Obviously you didnt. His comment was as much of a calculation as any other claim of battery life on fon a forum.

If you read this original article, they are using a script to test the battery life. This guy just woke up, upgraded his OS, scratched his head and looked at the top right corner of his screen. In what cave are these two comparable in accuracy?

Quality of his method, or comparability of his method to the test utilized in the original article has little to do with it.

robanybody commented "So it looks like far from battery life improving, it's got worse" and using his "real life" subjective values in showing this.

you corrected his values with the commentary

"Before : 8 hours
Now : 9 Hours
= it's got worse "

You used his subjective "never had more than" 8hours figure, and combined with the "In consequence I expect I'll be extremely lucky if I get more than" 9hour figure.

That 9hour figure was not his subjective measure, so you make reliability of his subjective evidence even worse.

Comparing apples with oranges.

my reply to you simply corrected the values you used, with the actual claim that robanybody made.

Comparing apples with apples.

They may be worthless apples, but that's a different discussion that you appear to be trying to shift the goalpost towards.
 
I was just gifted this laptop today. Sweet! Finally, I'm at the leading edge rather than always taking hand-me-downs or buying used equipment. 15 hours on this sweet machine is going to be a huge change from what I was suffering from before, lugging around a power adapter and external hard drive with my 2007 MacBook Pro. Hello portability! :)

Preview is completely broken. On both of my machines I had Mavericks on, had to go back to ML to get any work done.

Broken how?
 
Same fab battery life here

The jump in battery life is fantastic - I love it!
Light web browsing will get you around 15 hrs, but obviously pushing it hard will drop that significantly. But with the latest MBA, you get the combination of great battery and serious grunt if you want it. Never seen this on any Windows laptop.
It also runs really cool too - can't feel any heat from the bottom in normal use.

Idle power usage appears around 2.6W, constantly loading web pages uses around 7.8W.
My battery reports a full capacity of 52W.

A truly quality product worth every penny - you get what you pay for in laptops.
