So, I got a refurbished MacBook Air a little bit ago and I like it overall, but the battery seems to die really fast. I had thought Macs were supposed to have very good battery life and I can't remember specific numbers for the air, but I thought it was pretty sizeable, but my battery lasts about four hours tops. Is this standard and is there any way to maximize battery life?

I would assume that Apple would have put a new battery in the MBA. You can check the # of battery cycles. IIRC, the MBA battery is good for ~1000 cycles.

People average different life reports because of different usage.

User 1: With news.yahoo.com opened, a text document, and Google Chat up will probably get 8+ hours of usage.

User 2: With youtube running, iTunes playing music, Skype video chat, and a game minimized will probably get a lot less, 3-4 depending on how intense the game is.

I can even get 12 hours showing with minimum brightness and a text pad opened :). lol. But my average use is 7 hours with RDP and light web usage.

Also, is it an Air 11 inch or 13 inch?

@simsaladimbamba: thanks, reading that now

@TheRealDamager: Okay, maybe I should change my brightness then.

@Stchman: how would I go about checking that?

@BigMcGuire: that makes sense, its a thirteen inch. I usually just use internet and itunes

Advertised battery life is under ideal conditions, in reality it varies depending on what each user is using it for, whether it is very CPU/GPU intensive and certainly screen brightness is a big factor as well.

For simple web browsing, at 50% brightness I ususally get sligthly over 4hrs.

2010 13" MBAir here and I use mine while at work. I have even left my charger at home a couple times. Even if I start at ~98% battery charge once I first open it up at work, I can run iMessage, Mail and iTunes all day. Now on the couple days that I didn't have my charger, when I closed the Air to leave work it was at like 7-12% but it does in fact last me all day(8hrs).

I've been having huge battery issues with Mountain Lion, damn. I went from 6-7 on my normal use to around 3. I keep it on 25-35% ish brightness, light browsing, with music in the background and occasional TV shows in VLC. I really hope Apple does something about this since I don't appear to be the only one having battery issues.

It's perfectly normal. I have a MacBook Air, and after listening to iTunes in just a few minutes, I already drained 7% of my battery life. Editing in FCP X takes 1 hour, Intense games 1 hour, surfing the web is 4 hours.

This MacBook Air is just 2 Months old. And it's perfectly normal in health.

One thing that is somewhat overlooked or underestimated is tweaking your screen brightness. The brightness affects battery life just as much as the tasks you do on it.

Whenever you are running on the battery, you should lower the brightness completely down, than raise it till you find the brightness acceptable, and leave it there.

And if you are using it outdoors and must have the brightness cranked, dont be surprised when the battery life is cut in half.

I'm pretty sure Mountain Lion has something to do with this. Hopefully 10.8.1 will fix the battery issues.
I keep telling myself, unless it's broken don't upgrade but I don't listen.

Battery & Network is affected. :( Patiently waiting for an update.

I was getting around 2-3 hours of my MBA 11 2012 to start with and i wasnt very impressed, until i realised i had dropbox & wunderlist running in the background, so i closed them down when i didnt need them and reduced the brightness a little bit (checking the battery life estimate everytime to see what it said) now im getting around 6-7 hours which i consider very good.

Is it an 11" or 13"? If it's an 11", then 4 hours sounds about right.

I'm going to try quitting dropbox when I don't need to update my files and see how my battery life is.
