Over Achiever

macrumors 68000
Over Achiever. On a daily basis I use it just for typing documents and sending email. So when I have just Microsoft Office 2011 and Apple Mail open, it lasts me for 12 hours. That is without dimming the brightness of the screen or anything. I do enjoy it!

A full brightness screen will deplete the battery much quicker. I get over 6 hours of usable battery life with 2-4 bars brightness, any more and I can't maintain 6 hours. This is after nearly 80 cycles of battery use now, and multiple calibrations. I feel like I know what I'm doing ...

12 hours?

That's what I'm thinking Bella. I can't wait! I used to get 3 years off a single charge on my old white Macbook.

Now you're just trolling.

Looking through your other posts and threads though I can't say I'm surprised. Quite a few of his threads are in the Wasteland.

He was recently in Time-Out due to the below threads [and a few others] so take what he says with a grain of salt.

How do you conduct yourself during that moment when you're in a cafe or other public place and you whip out your 11-INCHES and slap it on the table and all eyes are on you?

it wasn't anything to get too excited about really was it?

I meant I smell AN anticlimax

This thread is a gem too. Read the second post.

Now to stay on topic- I've never gotten more than 5 and a half hours from my 11" Air after 13 loadcycles (just one week old atm) with wifi off and brightness two bars above minimum.

That is ridiculous - you will only get the incredibly naive to believe this. I have a MBA 11 and a 13 - I know better.

Listen to yourself - you sound like this:

I put this additive in my gas tank and now my car gets 75 MPG!!

I lost 20 pounds in only one week eating only MacDonalds, donuts and chocolate shakes!!

I bought a MBA 11 inch just a few days ago. Since installing Click To Flash I am now getting 12 hours use out of it per battery charge. This machine is a monster!:D

I made a similar topic. You do get 8-9 hours with basic 11" if you just use Word with 3bar-brightness and WiFi off.

My MacBook Air didn't have flash installed out of the box, and it didn't get anything close to 12 hrs out of the box--I went a few weeks to see if I could go without flash like I do on my iPad. About five plus hours is what I got. When I installed flash, and click to flash, I also didn't gain anything (obviously). 12 hours seems unrealistic, even for just minor tasks.

Course ya did. ;-)

I got 19 hours out of my macbook air earlier on one charge.

Is it sitting there, not being used with the screen off? I don't see how you can get 19 hows on a machine with a 3-5 hour rated battery life. I call shenanigans.

Flash isn't installed on shipping MacBook Airs. Obviously, you would have had to first reduce your battery life by installing Flash and then increase it again by installing Click-to-Flash.

The obvious answer to this is why install Click-to-Flash at all, just don't install Flash. ;)

And of course, you'll have to be precise what you mean by "12 hours". This is not continuous use for sure because even at a brightness of 1 and with every app closed that is simply impossible.

4 hours' difference is a lot. No way OP got anywhere near 12 hours, unless he kept it in deep sleep.

In which case I get 30 days out of mine :p

So much exaggeration going on in this thread...

I use my MBA '11 as a glorified typewriter. Typical writing session:
1) WiFi/Bluetooth off
2) Brightness @ 50% (often less, if I am in a brightly lit room)
3) only (repeat only) program I run is Word

The best I've managed is about 10-10.5 hours.

Even that I find quite dubious.

In a most minimal, do nothing state I can barely get the machine to crack the ten hour mark by calculated drain. That is on the first tick of brightness, machine on with no apps loaded, confirmed less than 1% of CPU by any background processes, me _not touching it_ for at least a minute. My battery is well calibrated at 98%. If you somehow got a well above spec battery, possibly, but I think you're adding an extra hour minimum into your estimate.

WTF, you guys got a monster MBA or mines's just a ****** MBA.

MBA 13"
1,86 GHz, 4 GB

Battery lasts for almost 2 hours watching 1080p MKV video, brightness + audio both set to max values, Wi-Fi off, Bluetooth off.

You guys kidding me?

...my whitebook's battery exceeds its normal capacity as I only charge and calibrate the battery where I live off base in Japan so the power is 100/50hz.

The slower/lower you charge a battery the more full it gets (to over simplify it).

Brightness + audio are two of the most battery draining settings. Playing 1080p videos is a great deal more taxing then a word document... If you drive a car like a sports car you can't expect to get the rated MPG.

You guys kidding me?
Yes, yes they are.

12 hours?!!! Not possible even if you use Coolbook. That value is not possible for a continuous use of the machine. [PERIOD]

This made me lol.

This thread is full of bs. If you're sending emails, it means you're on wifi, and the screen is on. With only those 2 things on, it's not possible to get 12 hours of battery so thanks for wasting everybody's time.

Minimum Power Drain

While 12 hours does seem like a slight exaggeration, I can get close to 10 hours on my 11.6" MBA if I am just writing reports at minimal brightness with every thing turned off (wifi, etc). In normal use, where I write software, compile it, and test it, I can easily get 8-hours on low brightness because most of time is spent studying the code/results, and looking for bugs.

I have been very impressed with the 11.6" MBA's battery life (and low heat generation). It blows my original MBA away!

I think the Sandy Bridge model will be even better. I look forward to the upgrade (assuming I can stomach the GPU).

Well.. You might be right, but how can you explain this?

Brightness set to 1 bar, and just wirelessly browsing I can only get 6:30 hours, sometimes even less if I start to see a lot of images. Apple says it should last for 7 hours with 50% brightness and 30 pages on Safari. Too much marketing Apple?
