MacBook Air 11" Battery Problem

Just purchased the new MacBook Air 11" and only getting around 2 hours battery time as opposed to the 5 hours advertised.
I've had it about 2 weeks now and thought the battery might increase over the coarse of time, my main concern is I've only being using Firefox for browsing so nothing too CPU intensive and had hope to do some photoshop work on it at some stage.
Can anyone link me to any diagnostic tools to see if theres a problem with the machine. Activity monitor isn't showing anything unusual.

http://www.apple.com/macbookair/specs.html if you look at the bottom it notes the test was performed with just safari opened, and at 50% brightness. If you want similar battery life I would try setting the brightness lower; and make sure no other application is open. Also I would assume this test was done without flash installed.
Having flash installed will negatively effect battery life. http://www.geekosystem.com/flash-decreases-air-battery/ "reviews of the MacBook Air over at Ars Technica indicate that having Flash installed can cut the battery life by a third"
Apple actually posted a whole press statement why they chose not to include flash by default. http://www.apple.com/hotnews/thoughts-on-flash/

Macbook Air 2011 battery problem

Hello guys!
I bought Macbook Air mid 2011 11 inch model with 128 Gb and 4 Gb RAM. In last weeks I saw my MBA after full charge (all night) have 100%, but after two hours is 10%. Is it normal? I just worked with Google Chrome, Time Machine and maybe some video in HD in MPlayerX. What I can do?

Ah, I made a reply yesterday evening, it has disappeared.
I try to repeat it again:
Don't worry: you have the most beautiful and enviable MacbookAir! It's the latest version, and it's battery is also new. I guess there's nothing wrong with it. The only thing that is different with my MBP's is that there is 6,4 power usage (obviously with the charger in), could you check one thing for me:
Start Acitvity Monitor (in Utilities), and for <all processes>, click on the %CPU column, are there any processes that continiously use more than say 15%?
The battery values vary a bit, that's not abnormal (in my MBP they vary between 92-103%; 90 cycles, 28 months), they are absolutely not giving the impression that there is something wrong with the battery, it's life is not determined by what Coconutbattery says (a good utility btw), but by the number of cycles, read the pages I gave the links of.
Another thing: there is an EFI update, look in the Software Update (EFI is an hardware layer, compare bios in a PC):
http://support.apple.com/kb/DL1448.
If you do not have "problems", it is still good to update, because it may solve some issue that you have not encountered yet.
don't worry, have fun with your fantastic 13" MBA,
happy computing,
Lex

Macbook Air 2013 battery problem

Hi all,
I just got my brand new Macbook Air 2013 model today, I can't power it up until the AC Adapter is connected. When I finished all the setups, login into the system, I found out the battery shows 0%. This is my first Mac, would like to know if this is normal. Cause from my experience with windows laptop, they all comes with pre-charged battery. Thank you very much for your assistance in advance.

That's not normal, & if it doesn't begin to work as expected after say, 15 minutes, try
Intel-based Macs: Resetting the System Management Controller (SMC)
but it's likely that you have a faulty computer.

Macbook air Shut down problem

Hi everyone,
I used to have the shut down problem with my Macbook air. I have an 11" Later 2011 Macbook air.
The problem did not go away after updating to Mountain lion.
I just realized that although I was closing all programs, I was not ejecting my 3G modem/dongle.
Once I ejected it before commanding it to shut down, it did shut down properly.
I thought I should share it with you. May be there is a program that has not been closed or a devise that has not been unplugged/ejected properly and is restricting the shut down.
It worked for me. Hope it will work for you.
Enjoy your Mac.
J.

    Reset SMC.     http://support.apple.com/kb/HT3964
    Choose the method for:
    "Resetting SMC on portables with a battery you should not remove on your own".
     If this does not help, you may have to take the computer to the Apple store
     to have the battery checked out.
     Best,

Is there a way to create an AUDIO alert when my MacBook Air (Mavericks) battery runs low (say 10%)?

Is there a way to create an AUDIO alert when my MacBook Air (Mavericks) battery runs low (say 10%)? I often miss the visual power percentage in the top bar, so would like an audio alert as well.

For global alerts, yes:
There is no need to do anything before the alert appears, and the MBA will not lose data should it go to sleep. If it goes to sleep at 0% you still have several hours to plug it in before it shuts down.
I wouldn't even bother displaying the percentage value.

I have the Numbers-applications on both Mac mini and Macbook Air. My problem is that they don't sync so when I create a Numbers-file on the MacBook while travelling, it will not be on my Mac mini when I get home :(((

Hey iWeb plubishing problems,
I would first check to make sure that you meet the system requirements for OS X to support Documents in the Cloud. For that your Mac’s needs to be running at least OS X Lion 10.7.5 or later to make sure that everything syncs. Take a look at the article below for more information.

My MacBook Air's battery health is decreasing.

My Macbook Air's battery health is decreasing. I bought it around a year ago. Now it's battery health is 85%. However, it keeps changing. From 85% to 88% and sometimes it hit 90%. Is my macbook's battery healthy? And is it normal, because I bought it a year ago.
Here are my battery's properties:
Cycles ; 404
Health : 85%
Design Capacity: 6700 mAh
Current Capacity: 5703 mAh

i have to disagree with linc davis's reply.
system profiler, or what they call the system report will have your current battery health status. in power the system profiler will either display "excellent", "normal" or "check battery" the more charge cycles you have, (404 which you stated) the more the battery will loose some capacity. this is normal of lithium ion batteries
health 85 % is current capactiy (fully charged) divided by design capacity * 100 or
5703 / 6700 *100 = 85%
my mac book air, having it for a year states
cycle count 163
Condition : Normal
Charge remaining 4223
full charge capacity 4263
but system profiler, at least on my mac book air running osx 10.8.2 does not list design capacity. so i am wondering where you got that number. the mac book air i have is the mid 2011 11" model
if you feel after 400 cycles your battery diminished and you have apple care you can always ask them to replace the battery, but if you did not get apple care, then the year warranty would be up. a new mac book air battery outside of apple care or any warranties is $129 before tax at the apple store.
eventually the more cycles you have ( a cycle is being fully charged from being nearly discharged ) the more you are going to have to replace the battery. whenever you feel you are not getting the charge you used to get the discision to repalce that battery is your choice, but eventually you will have to replace it.
for example say the battery used to give you 3 hours amd now it only gives you 30 minutes, then yeah replace the battery. but if the time lost in capacity doesn't bother you that much, then don't replace the battery now

Mid-2013 Macbook Air drains battery at hibernate

I recently got a new Macbook Air:
MBA 13-inch, Mid 2013
Processor 1.7 GHz Intel Core i7
Memory 8 GB 1600 MHz DDR3
Graphics Intel HD Graphics 5000 1024 MB
Software OS X 10.8.4 (12E3067)
The issue I'm running into is essentially that I close the lid (unplugged from power and anything else) and overnight the entire battery drains. When looking into the system log, I noticed that the sleep seems to run OK but it's when it tries to hibernate that the issue comes up. It looks to me like it tries to hibernate and runs into an error, tries again, run into an erro, tries again, etc.

This all seems to loop until the battery drains completely. Any Thoughts?

I have the exact same problem. I just installed Mavericks three days ago and I'm having battery drain when the lid is closed.
Does anybody have a solution for this problem ?

Macbook Air Poor Battery Life

I have a mid-2012 Macbook air and I've noticed recently my battery life is horrible. I've read every single other thread about this issue but nothing really helped and even the most recent is from a couple of years ago. Obviously now it's 2015 and my macbook is running on Yosemite, so its not the battery issue that everyone seemed to have with Mavericks.
Just writing that small section I went from 73% to 68% and at the current 68% I only get an estimated 2 hours and 10 minutes remaining. I've also had only Safari running this whole time.
Option clicking the battery icon reveals that the condition is normal, as well as the power system report. It also has gone through only 441 cycles, no where near its 1000 cycle "limit" and its health is already down to 77%. While obviously the condition is normal and doesn't say I need to replace the battery I feel that I should, based off of everything else.

Have macbook air from mid 2012 - I installed Yosemite November 2014 and since then I'm having problem with my battery - it has been draining super fast - 4hrs battery life now compared to earlier 8hrs.
I reinstalled Yosemite, didn’t help and then made a clean reinstallation of Yosemite about 5 days ago and there is still the same drain issue.
Thank you in advance!

Macbook Air Terrible Battery Life

There are a series of threads on these forums regarding the rare case where Macbook Airs get terrible battery life on Mavericks, and some of them have numerous posts telling you to make a new thread about your specific issue. Here's mine.
The issues began when I did my initial Mavericks update. I had a series of really bad things happen, so I did a cmd+R reboot, and reinstalled the OS. It didn't help, so I scheduled a Genius appointment, and they wiped the drive and installed Mavericks clean.
All of the issues are gone now, except for one: my computer gets less than half the life it did on Mountain Lion. I used to get 14-16 hours of battery life on Mountain Lion when nothing was running. I just charged it to 100% and had just 6 hours of estimated life.
I've reset both the PRAM and the SMC, and neither helped. Might you have any further ideas on how to fix this?
Note: I know that Google Chrome is less energy efficient than other browsers. With that said, I used to still get well over 10 hours at 98-100% battery life on Mountain Lion with Chrome open. My usage of Google Chrome is a constant in this equation; this issue can't be so easily dismissed as being an issue with Chrome, I think.
Here's a screenshot showing a number of things (no apps being open, the poor battery life, and activity monitor)

This may be because Spotlight is indexing your harddrive, do not interrupt it before it's finished and then it'll be much faster and your battery while behave normally if not better !

Improving the 2013 Macbook Air i7 battery life

Hi
I've checked couple of topics related to this issue seems many people suffer from this problem, i7 8gb ram with 512gb ssd Macbook air has some issues with its battery life it reduced very quickly. I've applied some techniques -like smc reset,deleting launch daemons and agents- and have an improvement in battery performance. Now the point is, when i do the EtreCheck there are many kernel extensions displayed in the report. Is there any way to delete them and slightly improve the battery life?
Here is the output:

Is there any other suggestions that you may offer ? Many thanks

You can use the new Activity Monitor to determine a unitless "Energy Impact" value:
You can also click the battery icon in your Mac's menu to reveal significant energy hogs (UPS is shown below):
Whereas Apple recently updated their apps to take advantage of Mavericks' energy saving algorithms, few other vendors have. I surmise the prominent "Energy Impact" hall of shame addition to the new Activity Monitor is Apple's subtle way of nudging them into compliance.
Google's plethora of invasive OS X system modifications is a popular reason for excessive battery drain. Google has yet to demonstrate the ability to develop efficient OS X apps, and one can only surmise they are not interested in doing so. If you elect to use Google Chrome or any other poorly implemented OS X programs, you must accept the detrimental effect they will have on performance and battery life.
If you no longer use a Blackberry, uninstall RIM's software. Be sure to follow its uninstallation instructions.

2013 Macbook Air 13" battery life not as good as advertised

At full charge, the estimated battery life read a little over 17 hours. At 97%, it now reads 15:39. Like I get this is vastly better than the older Macbook Air, but it still falls quite short of the 24 hours advertised on the website. Currently, it is still at 97% but now the estimated battery running time reads 14:59. Is this normal? I accidentally drained my battery twice since I bought it at the beginning of August, and I understand that's not good for the newer batteries - could this be the reason? My screen brightness is at 50% and I have no movies or music playing. Safari is the only ap I have open.
I'd appreciate any ideas or help with this problem (that is, if it is one).
I just looked at the estimated time again, and while it is still at 97%, the estimated remaining time is at 13:48. It's taken me a little over a minute to type this.
I'm not very tech-savy - is there something wrong with the way I understood the advertised battery life?

The Air is nowhere advertised for 24 hrs. batt. life......... in any configuration.

MacBook Air 3D graphic problem

Hi,
I have MacBook Air 2010 (2.13GHz, 4GB, 256GB SSD, Geforce 320M).
I have strange thing with 3D games on my MacBook Air. I tried to play 3D games such as Resident Evil 5 on Windows 7 (bootcamp). I used Win7 PRO 64-bit.
When I played 3D games with battery, the games run smoothly without any lag. However, when I plugged the power adapter and play 3D games with AC power, the games were lagging noticably during gameplay. I am sure that games did not lag with battery power.
   Anyone got same problem and know how to solve it?
Thanks and best regards,
Thiha

Hi Zipplet,
   Thank you for your valuable answer. I agree with you. It must be heat issue and CPU was throttle back and therefore the game lagged during gameplay with AC adapter. Now, I know that battery charging increase the overall heat in the system.
   I also heard (not sure) that serious trottle back happens especially in 2.13GHz MacBoook Air and it did happen badly in 1.8 GHz model.

MacBook Air 2013 battery drains quickly while in sleep mode

I just purchased a 13" mid-2013 MacBook Air this week, and so far everything is working well - a remarkable improvement over my 2007 MacBook! But, I've noticed that the battery seems to drain very quickly while in sleep mode. For example, it drained 10% over five hours. I've turned off bluetooth and made sure that the PowerNap option is not selected under Energy Saver preferences. And the battery health/capacity seems to be good. Are there other things that I should turn off/check out? Has anyone else experienced this? Is this even abnormal for the battery to drain at this rate while in sleep mode? Thank you!!
