MacBook Air 2014 battery drain OSX 10.9.5

Health Information:
  Cycle Count: 62
Seeing the sudden battery drain after the upgrade to 10.9.5, any suggestions?
Thanks!

Hi pandu9,
Thanks for visiting Apple Support Communities.
If the battery runtime on your MacBook Air is unexpectedly low, start with these troubleshooting tips:
Built-In Diagnostic Tools
A great place to start when troubleshooting battery issues is the built-in diagnostics that are available on your Mac notebook. Review the following articles for more information on using diagnostics.
Using Apple Diagnostics
Using Apple Hardware Test
Note: The additional troubleshooting recommended below assumes you have run the above diagnostic appropriate for your computer and that no issues were found.
My battery runtime is low
Identify what the battery life should be for the product you are troubleshooting.
The Tech Specs site provides Apple's battery life expectations for battery usage. The specifics for wireless web usage and standby time are included in the Tech Specs article for each product.
There are several common causes battery drain that you can minimize.
Take steps to optimize your battery life per the Optimizing Battery Life section earlier in this article.
A common cause of decreased battery life is a "runaway process." Make sure to check Activity Monitor for any runaway processes, especially after installing software updates or a new operating system. Installing updates is important to ensure optimal performance for all applications.
If you are still having battery runtime issues after optimizing your computer's performance and checking for runaway processes, test in Safe Mode. Safe Mode limits the active items on the system and allows testing in a more minimal environment. If the battery life is better in Safe Mode, you may need to do further software isolation for the items disabled by Safe Mode to determine what the power draw is while not operating in Safe Mode.

  • 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!!

    You can return a new Mac within 14 days of purchase.
    A new Mac is in warranty for 1 year from the date of purchase.

  • 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?

  • MacBook Air 2009 battery draining rapidly.

    The charge on my MacBook Air 2009 has been draining rapidly, last night I charged it overnight and this morning when I turned it on the MacBook is only charged to 11%. Any idea what is causing this? My MacBook says that the battery condition is 'Normal' and the MacBook was off whilst it was charging.
    I've literally only just had a new HardDrive installed so I'd really hate to have to have a new battery as well.

    Follow these steps to see the battery cycle count:
    http://support.apple.com/kb/HT1519
    Then look at the table below to see the maximum number of cycles your Mac is rated before the battery is considered spent and needs t be replaced.
    For your MacBook Air 2009 it is likely 500 cycles.

  • Too depressed to macbook air 2014 ( Battery, Hinges loose )

    Dear All,
    Please help me about battery macbook air Early 2014, currently only use 7 hour for web .

    Hey Hien Duong,
    Thanks for the question. You MacBook Air can have up to 12 hours of battery life. However, please keep in mind that this testing was performed with the following conditions:
    Testing conducted by Apple in March 2014 using preproduction 1.4GHz dual-core Intel Core i5–based 13-inch MacBook Air units and preproduction 1.4GHz dual-core Intel Core i5–based 11-inch MacBook Air units. The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 12 clicks from bottom or 75%. The HD movie playback test measures battery life by playing back HD 720p content with display brightness set to 12 clicks from bottom or 75%. The standby test measures battery life by allowing a system, connected to a wireless network and signed into an iCloud account, to enter standby mode with Safari and Mail applications launched and all system settings left at default. Battery life varies by use and configuration. See www.apple.com/batteries for more information.
    via Apple - MacBook Air - Technical Specifications
    http://www.apple.com/macbook-air/specs.html
    If your display brightness is set higher than 75%, or you are running additional applications (for example, GarageBand, Flash Player, etc in your screenshot) your battery performance may be affected. For more information on maximizing performance, see the following resource:

  • Macbook Air 2014 13" Battery Question

    Can continuously charging overcharge the battery of my Macbook Air and does it count as a cycle? I've heard that the Macbook Air has 1000 cycles. Currently I have done 10 cycles. So what's better?
    - Charging it to 100% and unplugging it until it goes down to 20-30%
    or
    - Leaving it plugged in all the time?
    I searched everywhere but I wasn't able to get the answer I was searching for?

  • Macbook Air 2014 hinges loose

    Dear Everyone,
    The first i want said sorry about my english is not good
    I just bought a 13" MBA a 20 days  ago, after 2 weeks of usage, i noticed the hinge were kind of loose whenever i lift the MBA up, the screen/display will tilt backwards easily. Thus i call to the service centre to ask about it issue , the technician mentioned that he will tighten the hinge and do not worry but But I think a new product within 20 days of purchase, but must go to a service center, it is so bad
    Anybody encounter the same issue as well? Should i go to the service centre for repair it ? Actually if not better more and do not want use apple computer anymore, default i love machine and OS software and even used over 3 years from the macbook pro, Retina and now macbook air 2014. The first is battery and now hinges is loose.
    Regards,

    It's under warranty. Take it in for service.

  • 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

  • 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.

    My macbook air 2014, running on yosemite has been having sound fluctuations in particular during video playback. Both on quicktime and VLC. Fluctuations happen even when I have my headsets plugged in.
    Anyone able to assist?

  • Macbook Air 2014 is very slow after waking from sleep

    Constantly, when using my Macbook Air 2014 without power cord (which I am required to do at College), when my laptop goes to sleep, and I then immediately click to wake it up, it takes at least 20 seconds before the log on screen will come up.  The machine has also crashed twice in the past week.  Is there a solution for this? 

    You posted in the iPad forum instead of the Mac Book Air forum. To get answers to your question, next time post in the proper forum. See https://discussions.apple.com/welcome I'll request that Apple relocate your post.

  • USB 3.0 external drive extremely slow on Macbook Air 2014

    Dear Apple Support Team & Folks in Apple Community,
    Seriously, I have a problem with my new Macbook Air 2014 which has equipped with USB 3.0 port. I read through the forum and hardly find a solution for this.
    Recently, I plugged in my USB 3.0 external drive and expect that it would reach the same file transfer speed as that on my PC. Instead of 625 MB/s (5 Gbit/s), it was hardly reaching 60 MB/s (480 Mbit/s) to my surprise! Sounds like Macbook Air doesn't recognize USB 3.0 device properly. I have tried Western Digital and Seagate devices but failed to get reasonable transfer speed on my Macbook Air.
    I tried it again with my USB 2.0 external drive on Macbook Air and only got the transfer speed around 15 - 20 MB/s which is disappointing.
    Any patches or Firmware updates would be appreciate!
    I have OS X 10.9.3 already with EFI and SMC update patched by App Store.

    I would be interested to know which consumer grade non-raid external harddisk that could reach 6xx mb/sec.
    The speed you mentioned should be normal, since most of these are 5400rpm drives (asumming it is 2.5 inch).

    Hi there, I have MacBook Air (Mid 2012) with OSX 10.8.2. I want to update to latest OSX but it is saying that I need to first install MBA Flash Firmware Update 1.1.

    If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
    If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault boot volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main screen.
    There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode.
    *The linked support article refers to OS X 10.9 ("Mavericks"), but the procedure is the same for OS X 10.7 ("Lion") and later.
