For those with macbook air 13" i5, how much are you getting from your battery? I just did a calibration on mine but so far I am only getting 8hours under medium load. Is this about right. Does anyone actually get 12 hours? How is this achieved?
 
From the Apple site.

Testing conducted by Apple in May 2013 using preproduction 1.3GHz dual-core Intel Core i5-based 13-inch MacBook Air units and preproduction 1.3GHz dual-core Intel Core i5-based 11-inch MacBook Air units. The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 12 clicks from bottom or 75%. The HD movie playback test measures battery life by playing back HD 720p content with display brightness set to 12 clicks from bottom or 75%. The standby test measures battery life by allowing a system, connected to a wireless network, to enter standby mode with Safari and Mail applications launched and all system settings left at default. Battery life varies by use and configuration. See www.apple.com/batteries for more information.

What are you running? Screen brightness level?
 
Basic stuff, internet, and some videos and music here and there.
 
Im getting 13 hours with Skype, safari, and Xcode running and occasional iTunes radio listening with headphones. Display brightness set to 12.5%:eek:. I've gotten used to the dark brightness over the years. Always had my hp at 0% brightness. I'm also running mavericks. you do get a large amount of power savings and a decent performance boost.
