New MacBook Air 11 inch Battery Problems

I just got my new mac book air home and ran a full charge into the battery.  Once i disconnected it from the power adapter i noticed the battery was still only showing around 4 hours of life.  Nothing was running on the matchine at the time, other than a wifi connection.
As I started to use the machine (writing an email in a single browser window) the batter indicator began to jump in a seemingly iratic way.  After 30 mins of use, the batter indicator was showing less than 2 1/2 hours life remaining.
I've run the latest software updates and the same issue persists.  My machine is an 11 inch 1.6GHz model running the i5 processor.  I can see a few people have had issues in the past with eratic battery indicator behaviour but cant see any difinitive solution?

There is no definitive solution.  The time remaining indicator provides an estimate only based on the current load on your system.  When you first start using it, there will be more activity than normal as your system is set up and Spotlight indexes your files.
Think of your computer as being a car.  If you're going along a flat road, you can keep the gas at a steady level.  At that rate, maybe you can get 100 miles out of the gas you have remaining.  Now, if you suddenly go up a steep hill, you're going to have to use lots more fuel and all of a sudden, you may only get 50 miles out of the gas you have remaining.... but if you get to the top of that hill and then start coasting down, you might be able to get 200 miles out of the gas you have remaining.  How many miles you can get out of the gas you have remaining will always change if you measure it by what your car is doing "now".  However, if you look at the gas gauge instead, it will not fluctuate that way... it will always show you how much gas you have remaining.
To get the same accurate "gas gauge" reading, you should view your battery by the percentage remaining vs. the time remaining.   The percentage remaining is the "actual" percentage of your charge remaining.  The time remaining is only an estimate based on your current usage and it can fluctuate wildly depending on what your system is doing.

  • 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 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.

  • New Macbook Air 13" battery questions?

    I just got my new Macbook Air 13" i7,8gb Ram/512GB SSD last December 25. I just came to notice after fully charging and using it (straight usage, no powering off doing installing, learning, etc... beacause I'm new to Mac  ), It doesn't reach 12 hours, maybe it took 6 hours Max to recharge again on 10%.
    Is it normal for a newbie? or it should be really 12 hours usage in reality?
    Please advice.
    Thanks in Advance..

    12 hours quoted is the result of testing the battery under lab conditions.
    Battery runtime will be lower  when battery is under real life conditions.

  • 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

  • New Macbook Air - Possible Battery Issues?

    Is it normal for my new 2013 macbook air to lose a tremendous amount of power overnight when it is sleeping? When I put it to sleep at night with over 50% remaining on the battery, the charge is usually about 10% in the morning. Sometimes the device is extrememly warm as well.
    I did change the sleep settings so that it does not save the info on my RAM to my SSD and locked the sleep image file to prevent the computer from using it. Is that a possible reason for the battery issues?

    I "fixed" it by reverting my sleep settings back to default hibernate mode 3, which means that every time I put the computer to sleep it will save my RAM to the SSD via the sleepimage file.
    As of changing that setting back, my Air has been been sleeping properly (I think).
    I didn't find a solution where I could prevent the sleepimage file from being created/used every time I put the computer to sleep and still get the Air to sleep properly.
    I think what was originally happening was that because I locked the sleepimage file, the computer spent the entire time it was suppose to be sleeping trying to access the sleepimage file - causing an enormous amount of battery drainage over time.

  • New MacBook Air 13´´ - battery drains really fast

    So I bought yesterday MacBook Air 13´´. I assumed it was going to be fully or half charged but the battery was dead when I opened the computer. Then I put it on charge and it took about 2-3 hours to fully charge it. After that the battery started to drain really fast, and I didn't expect that. I supposed MacBook 13´´has a battery which could last for about 13 hours, but this is to strange. I don´t have experience with Mac, this is my first Mac, so any suggestions would be appreciated.
    P.S. I updated OS X cause App Store said there's an available update. Don´t know if that has anything to do with it.

    I´m currently in Germany and I´m flying back to Croatia tomorrow. So I won´t be able to do that. :/
    I´ll try to drain battery to 0%, then recharge it again. I read somewhere that could help for first time charging and recharging.
    Don´t know is it normal for Mac to come with drained battery?

  • New MacBook Air Photoshop CC Problems

    I recently bought a 2014 Macbook Air. I own a Mac Pro which I generally use for Adobe CC, but I wanted something I could do light work on portably. As soon as I started working on Photoshop things were going crazy. The images started distorting, backgrounds would show my computer background instead of the default white background on photoshop, and the paint brush tools were pixelated. I don't know what is going on, and any help would be appreciated, as I have never had these kind of problems on my mac pro.

    Go through the GPU troubleshooting steps in this document.
    Photoshop CC and CC 2014 GPU FAQ
    My thought is that the GPU shares the main memory and I'm thinking 4 GB is very sparse. Can you at least bump it up to 8 or 16 GB?

  • New Macbook Air - wifi connectivity problems

    Well some of you got the problem solved, but for me who has purchased my first apple device besides an Ipad, this is ridiculous.
    It has been more than a month and have received 3 updates, 1st was seed update , then the new version and then a software update.
    What is ironical is that none of the updates fixed the issue. The internet doesnot connect whenever you wake up your MBA after the 3rd update, earlier it used to just drop in between. Now have started seeing the browser in a Hung mode. The page would not load at all. The only way one can make the thing work is to restart it.
    I would definitely want some permanent fix to see my hard earned money not just going down the drain in an Apple.
    <Edited By Host>

    Why all these questions about routers and so on?
    Apple is delivering a defective product, no more no less! The fault is with some ( or all?) 2013 MBAs and Apple is really not handling this in a way that can be expected.

  • The NEW MACBOOK AIR ***** PLZ SOMEONE HELP ME GET THIS ACROSS TO SOMEONE AT APPLE

    Hi,
    My Name is Essa and i live in Bahrain. I fell in love wih apple ever since i bought a macbook in 2005. The laptop (which im using now) has been with me for over 6 years. Not only i was happy with my product, i purchased more products, such as 3 iphones, all for me, a ipod nano the new one with the touch screen and the first edition of the iPad. I have never had a problem and everytime i would tell my friends if they needed a laptop to get a mac and be safe with it. I decided in august to get the new macbook air. The problem after a few months of using it, it started to act up. By act up i mean everytime i start it up the computer would freeze on the welcome screen and the arrow would be stuck in the top corner, and after several times of trying to start it up it just kept giving me that (PING) sound and would not load. I took it to the sale agent here in bahrain. They are called Apple Center. They were extremly nice, and worked on my laptop and they came back to me and said that there was an error with your logic board and it will take 4 weeks to fix it, as they had to recieve the parts form the states. I gladly gave them my laptop and waited for 4 weeks, keep in mind that i still used my old macbook in 2005 and it was stable as the day i bought it. After 4 weeks of waiting they said we have fixed the problem, and he showed me that the laptop was working fine. I closed the top keeping it on sleep mode. When i got home i realized that the same problem exisited that when the operating system loads up the cursor is stuck in the top left corner and mouse pad and keyboard were not working. After several times of shutting down the laptop and starting it up again i ended up with the same result. It kept giving me that (PING) sound and wouldnt load. I will be taking my laptop in on monday morning again and im assuming i will be waiting for another 4 weeks maybe more. Could you please explain to me what happened to Apple? What has made your company start producing laptop that were as crappy a windows based computers. The reason i switched over is because i found the stability is outstanding and nothing could go wrong. Plus the old laptop which im sending the messege from is my old macbook. It is still good, and doesnt crash. So why did i just spend over 1,500 dollars for a laptop that died after 3 months of purchase? I dont know how well apple takes care of their international customers, but to be honest i am fairly dissapointed with this product, and i wish that i didnt buy the new macbook air and just stuck with the old one. Please if anyone reads this msg and is able to help me in anyway to send it across i would greatly appreciate it. I will be posting my phone number at the bottom hopping for a call from apple.
    For those who read this and help i owe you a lot, if I dont get any replies or a responce from them im sure that i am screaming into a black hole and that apple really do not care about their customers and instead of winning i would just choose a different product from now on.
    Regards,
    Essa Al Alawi
    Hoping for someone to answer me back

    Don't take your laptop back. Find out the number for Apple Care in your part of the world and call them. Tell your story to them. If the person on the phone can't help you, ask for their supervisor. Keep asking for supervisors until you get exactly what you want to get. If that mean you want to get the problem fixed without having the computer gone for four weeks, then keep asking for supervisors till you get someone who can do that for you.
    Be prepared to be on the phone for a while, so arrange a speaker phone, water to hand etc. Be patient.
    As for "crappy computers"--my MBA has worked flawlessly since the day I got it. As good if not better than any Apple laptop I've ever had, and I've had several.This is the thing though, there is a percentage of failure rate that occurs in electronics. It occurs whether we're talking about televison sets or toasters. If it's electric, it has that failure rate. Now sometimes a thing will be bad and in that case the word gets out and everyone knows that particular electronic has surpassed the normal failure percentage. The Airs, however, have not done that. Their reputation, so far, has been incredibly solid and good. So you can assume that you, unfortunately, got one out of that small percentage of electronics that have an issue.
    Laptops, let us remember, are doing a lot in a very small area. A lot can go wrong, and it's pretty amazing how many don't, especially given how many are made and sold. Sometimes we get the bad apple in the barrel, it doesn' t mean that the company making it has gone down hill. We hope the manager of the store, or the company, or someone will do right by us. If they don't, then we need to make sure they do. Keep asking for upper management till you get what you want.

  • Adaptive charging in "new" macbook air?

    Hi,
    I've seen many peoples wondering about the new macbook air's battery.
    But didn't clear me up.
    So I'm still wondering about the adaptive charging used in the macbook pro's.
    Does the new macbook air have adaptive charging or not?
    and if so, are they functioning as the macbook pro?
    Because in one of those topics someone asked the same stuff, and the answer was: "type=yes, Size=no"
    So the new macbook air series are will adaptive charging chip, but are they functioning with 1000 charging cycles?
    I'd understand that the mba won't last for 7 hours or anything like that as the macbook pro, because its not a battery with the same quantity cells, cuz the mba uses a lil bit smaller battery.
    Anyways, I just want to know if the new macbook air series are built-in with adaptive charging, and if they are functioning.
    Thanks

    I cannot be absolutely sure - except that when the latest revision of the MBA was released - Apple never announced that feature in the battery - and - they really made a big deal of it last fall when they released them with the MBP.
    So - I think they didn't mention it because that technology is NOT in the MBA.
    If it was they would flaunt it to sell more MBA's.

  • Calibrate new macbook air

    H guys
    I just bought my new macbook air 2013, Do I need to calibrate my new macbook air's battery after unboxing it?

    No, as per Apple, current Lipo batteries in the Air do NOT need calibration
    How to TREAT your new Air batteries:
    Keep it plugged in when near a socket so you keep the charging cycles DOWN on your LiPo (lithium polymer) cells / battery.
    *Contrary to some myths out there, there is protection circuitry in your macbook and therefore you cannot 'overcharge' it when plugged in and already fully charged
    If you leave your macbook plugged in all the time, take it off charge and drain the battery down to 15 or 20% every couple of weeks or so.
    LiPo (lithium polymer, same as in your macbook) batteries do not need conditioning. However...
    LiPo batteries do NOT like to be dropped down to 15% or so often,....key word being "often"
    A lot of battery experts call the use of LiPo cells the "80% Rule" ....meaning use 80% of the charge or so,.. then recharge them for longer overall life.
    Never let your Macbook die from power, you can corrupt files that way, and the batteries do not like it.
    The only quantified abuse seen to LiPo cells is instances when  often the cells are repeatedly drained very low.
    Contrary to what some might say, LIPo batteries have an "ideal" break in period. First ten cycles or so, don't discharge down past 40% of the battery's capacity.
    Same way you dont take a new car out and speed and rev the engine hard first 100 or so miles.
    *Also, if youre going to store your macbook away for a few weeks or more,... make sure it has at least a 50% or so charge.
    *Cycle count / use/ lifespan is one thing that cant be countered.
    Proper treatment is another thing. Just because LiPo batteries dont need conditioning in general,.. does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesnt need conditioning.
    Just use and enjoy your new macbook, 
    From Apple on batteries:
    http://www.apple.com/batteries/notebooks.html
    http://support.apple.com/kb/HT1446
    but really all you would keep in mind is --"consider 20% is the same as 0% and recharge it"
    and best "tip" is if its near a socket, .....plug it in as long as you can (especially at home) since cycle count on the battery are the "miles that wear out the tires (battery)"

  • New MacBook Air arrived with low battery; is this a problem?

    Hi,
    I ordered a new MacBook Air 11.6 (2014) model from Staples and when it arrived, the battery had only about 1.5 hours left on it.  I understood that the MacBook Air shipped with a fully charged battery; this is also noted in Apple's 'welcome' guide with the computer. 
    Should I be concerned about future battery life with this computer?  If this is not normal I still have time to return/replace it.
    Thanks for your input/assistance. 

    MacBooks leave the factory charged to about 50% but the battery will slowly discharge even if it is off. Staple's probably doesn't have a really fast product turnover when it comes to Apple notebooks so it wouldn't surprise me if its been on the shelf for a while. As Oglethorpe said, charge it up, use it on battery after you've charged it and repeat several more times. If you are still worried about battery life contact AppleCare.

  • New Macbook Air with bad battery life

    I've got a new Macbook Air (2013, 11-inch) and I upgraded the RAM and the processor. I'm only getting 6 hours max from the battery, which is disappointing because I wanted to be able to do a day's work without a charger. I've already sent one back and had it replaced, but the new one has the same problem. I've done a call with Apple Support, where they directed me to the help article I'd already read. I've checked Activity Monitor and killed everything I can. I've turned off Bluetooth as well. I use Chrome a lot, Tweetdeck is running, but neither of these things I'd expect to result in a 6 hour battery at 100%.
    Does this sound like normal performance? If it's the processor speed, I'd be tempted to return this one and downgrade the processor as battery life is more important to me than speed (my work is mostly online anyway).

    Quit Chrome and try Safari for a while. See whether there's an improvement.

  • I have a brand new MacBook Air 11 inch, 4gb RAM and 256 gb SSD where the screen flickered abnormally and got dead all of a sudden while uploading a photograph in FB. Can anybody help?

    I have a new MacBook Air 11 inch, 4gb RAM, 256 SSD and use Mavericks OS. It is still under waranty period.
    Just few days ago while I was uploading a photograph in facebook, the screen started flickering abnoromally. I tried using the escape button but nothing was working so switched off by pressing the power button.
    After few minutes I tried to switch it on but my system never waked up. Called up the Apple Support, did SMC and PRAM but nothing worked. Then I was advised to take it to Apple's authorised service centre.
    At the service centre the engineers diagnoised and then said that the MLB/mother board needs to be replaced. Had waited for six-long days and today they had replaced the MLB/mother board. Now, the system came to life but nothing has booted. The screen goes white and a '?' question mark icon keeps on flickering.
    After thoroughly diagnoising it the engineer said that now the problem is with the SSD and the worse thing is all my important documents and photographs etc are no more there. And I don't have a backup of the same!
    While Apple Support contact centre is assuring they would replace any other parts if found faulty, but I feel differently. First, the MLB/mother board was changed now they say it is SSD problem - so if the SSD too is replaced there are possibilities of more faults coming up. All I can see and feel that this particular machine has turned out to be architectually deffective that calls for immediate replacement.
    Right now I am using a friend's windows pc to write this mail.
    Feeling completely miserable - all my expectatations gone after investing in such an expensive machine, loss of all my data, wastage of time and energy and to top it all affecting my daily work.
    Can anybody please advise what shall I do?

    Take the system to an Apple store to be fixed or replaced as the one you have has defective hardware.
