    I'm running with about 75% brightness and a little keyboard backlit and I'm only getting around 8 hours of battery life.

    The only programs i'm actually running is Google Chrome and Skype, possibly off and on with steam, nothing too major and getting 7-8 hours battery....What am I doing wrong?

    Using Chrome instead of Safari.

    I like safari but whenever I use the back button, safari will reload the page which will take around 3-5 seconds when chrome seems to save it. Weird is there any way to enable cache?

    Give it a couple of charge cycles to see if it makes a difference.

    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 for more information."

    I use Chrome and get the estimated battery life.

    There's your problem.

    I normally get 12 hours battery life, however, if I start running iPhoto movie mode and a few other intense applications, my estimates will drop down to 7 or 8 hrs. When I stop running those apps my estimate will increase. So keep track of what you are using and how much and how often. Some apps will eat up more battery life.

    Sounds unbelievable as 11'i5 starts crying at 5 hours and 13 minutes on using VMware, flash, regular surfin, word processing :(

    Other than having unrealistic expectations, you're doing nothing wrong.

    Is this really a fair point? They're not unrealistic expectations, they're what Apple said.

    Apple also defined how they came up with these estimates. The OP isn't matching them. So, yes, it is a fair point.

    Swipe instead of Back Button

    Tehsprayer - not in reference to your original battery question, but in your second post you mentioned how Safari reloads each page when you use the back button. Instead of using the back button, just do a 2 finger swipe (to the right) - that will instantly take you back to your previous Safari page - quick and easy, with no page reload.

    P.S. I am getting a regular 12 hours (or so) with light usage - the one thing I found that impoacts that is Flash, and now that I have clicktoflash installed, I am amazed at how widespread the use of Flash is in browsers - many of hte pop-up adds are Flash based, so one even pages that might seem static, Flash is running and consuming more battery and CPU cycles than necessary.

    Both Skype and steam are resource-intensive apps and can drain a battery faster than many other apps. In addition, it's possible you may have other processes running that are contributing to shorter battery life. There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.
    The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

    IOW, the OP was not replicating the same conditions under which Apple developed their battery estimates.

    What is it that people find so hard to understand about this and then assume their MBA has a hardware/battery problem? :confused:

    For basic tasks the MBA definitely gets 13 hours, when you start doing anything CPU Intensive it drops down, that's expected.

    I am gesturing to go back and it reloads the page, that's why I'm sticking to chrome.

    And I don't think leaving Skype on will drain the battery by 4 hours and I hardly go on steam.

    It would help people answer your question(s) if you mentioned what model Mac you had including screen size and year.

    Chrome has flash included. Those random flash ads run a lot of cpu. Safari doesn't have flash included. As long as you don't install flash Safari will be better for your battery

    pretty sure he's talking about the 2013 13" given the fact that he's "complaining" about only getting 8 hours.

    You would assume that, but to assume makes an ass of u and me. For all we know the OP has the 11" and is confusing the battery life with a 13".
