View Full Version : Macbook Air (2010) 13inch battery life

Feb 2, 2011, 02:40 AM
Just got my macbook air in late December. I have been using it for a month now. I love everything about it except the battery life. I feel like I have a defected battery in my air. It only gets around 4 hours of battery after fully charged. I even dimmed my screen down to one or two bar and I turned off the bluetooth and the battery life still says its getting 4 hours. I don't know what to do.

Should I call Apple and say they should replace it?

How long does your battery last in your macbook air?

does it actually shut down in 4 hours?

my experience with mine is that the time shown fluctuates a lot...sometimes up to 14 hours, sometimes down to 5 (when there's still about 80-90% left in the battery). Try just showing the percentage instead of the time remaining if it's stressing you out.

Or if you're actually only getting 4 hours, maybe it's the programs/tasks you're running. streaming on youtube or something?

if you're running light tasks and still only getting 4 hours of actual usage time, then yes, i'd go see a genius about that.

Have you calibrated it yet?
And how long does it really last, despite what the Menu Bar battery item says?

What is the brightness set to?

Are you using flash intensive websites?

Are you using intensive apps in general?

Sometimes turning the brightness all the way day to the least(1 notch above zero) will save you some battery life.

Disable flash - It does make a difference. I use Opera where it's built-in (Quick Preferences -> Disable Plugins), but there are plugins for most browsers so you can disable it. And sometimes they allow you an easy click when do want to watch it, as below:

I get about 7 hours on light browsing. With wifi off I get about 11.

That reminded me. Turn off bluetooth as well when not in use
