Macbook Air 11" mid 2013 battery

My macbook air 11" mid 2013 serial # C02KTARJF5N8 is showing only 4:30 hrs on the battery meter at the top on a full charge and is advertized to last for 9 hr

I would suggest going into the apple logo, selecting about this mac, more info, then system rpoert, from there you will see power. Click on this and It will show a charge remaining and cycle count, ring apple with this info and they will tell you if theres a problem straight away. It will alsow show the condition and you will find out more info there. Also if your running RAM heavy apps this will effect battery life, but if theres a fault you will see it there. Any issues ring apple and they will tell you if theres an issue hope this helps

Can I use my Macbook Air 13" mid 2013 with plugging charger even at 100 % battery full charge?

I can't decide whether using My Macbook Air 13" mid 2013 with charging power adapter connected even though it is fully charged Or using Macbook Air with unplugging charger after fully charged. Please advice me to maintain my Macbook's battery at good condition.

It will not hurt it as long as you do not leave it on the charger for an extensive period of time (say, days).

Macbook Air 11" (Mid 2013) takes time to become active after being inactive for a while

I've got Macbook Air 11" (Mid 2013). But it has an issue of taking up some time to be active after it has been inactive for a while (like when i dont use it for a while the macbook autosleeps and then when i want to work on it and try to get it active the screen only shows mouse pointer in a black screen and then the other components like the small window where you enter password and other takes time to appear...)
plz help...I've been facing this problem for 2 weeks now...and wanna fix it as soon as possible....plz help...

Hope this helps.

How come my Macbook Air 11inch mid 2013 is running very slow?

I recently bought it new, then couple months later, the fan would play very loudly, and everything went slow and laggy. I checked activity monitor and it says kernel_task is taking up a lot. Please let me know if there are any ways to make my macbook run back to normal, thank you!

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or low voltage readings from the battery of a MacBook, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on AC power, charging is causing the machine to heat up. That behavior may be normal for some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

My Macbook Air 11" (mid 2013 upgraded with Yosemite 10.10.1) freezes at 30% or 50% when booting.

I have tried SMC and PRAM resets at boot up but still have the problem.
I can start in safe mode OK.
Any ideas welcome.
Thanks

MacBook Air 13" Mid 2013 Display go Blank

I have set my MacBook Air Energy Saver setting to its default settings...
When its go on standby mode then i click/swipe on trackpad immidiately , Display going blank but keyboard Is working.
And if i wait 10 to 15 sec after standby then there is no issue.
Please Advice me how to fix it

If you take a look at these (very lengthy) threads, you will see this is a widely reported problem, for which Apple have yet to produce a solution. It is said that they are working on a firmware update that will address it but this has been talked about for a long time and still no update.
https://discussions.apple.com/thread/5118135?start=0&tstart=0
https://discussions.apple.com/thread/5475679?start=0&tstart=0
https://discussions.apple.com/thread/5495588?start=0&tstart=0
The current "solution" (which is not a solution) given by Apple is to set sleep mode to 'never', or to wait a few secconds after sleep before waking the MBA, or install the free App 'Caffeine" which allows you to manually activate sleep and wake.
Some persons have claimed a "bare metal restore" of the operating system resolved the problem but others have tried this without success.

Macbook Air 11'' (mid 2013) My display isn't running as smooth as it was before, especially when using multi-gesture commands

Hello, the major issue is that when I use a multi-gesture command like 2 finger swipe to check out my notifications or when I use 4 finger swipe to switch between apps, the edges of the app or window kind of get cut. Ignore the ghost effect in the picture. That's just because of the camera. Anyway, so you see that some widgets and the window on the right are like cut. Also when I do 4 finger swipe up or down, the windows don't move smooth at all. It looks more like a horribly done stop motion movie. An other thing is that when I hover over the dock, the magnifying effect vibrates for an instant before it fully magnifies and also when I'm hovering away it vibrates before it returns to its normal size. Also when I move the cursor quickly from one side to an other within the dock, sometimes the dock also gets cut. I started to notice these issues a little while after the update for issues with WiFi and Photoshop, maybe it has something to do with that. Any help is welcome.

Mid-2013 Macbook Air: question about the battery life

First of all, I'm sorry if these questions have been already asked, I've looked around and I've seen some answers, but none that fit my specific case.
I have had this computer since December (Macbook Air, 13'', Mid-2013), I've been using it for a month now. At the beginning, I used to use it until my battery was low (between 10 and 20%) and then charge it. Then I learnt that it's better to keep it plugged as much as possible (I have read this in other discussions and on the Apple page). The problem is that my battery is no longer a 100% of its capacity according to Cococnut Battery. It started with 99%, then back to 100%, then 98, 97... and now it varies from 97 to 98 (right now it says that my computer's current capacity is 6948 mAH). I don't know if this is normal, or if this is caused by the use I used to give to my macbook air at the beginning or by any other thing. I also have 19 loadcycles already. Besides, I have noticed that sometimes it jumps form 100% to 99% of battery pretty fast when I don't have it plugged, and I'm not sure if that happened before.
This is my first time dealing with a macbook and I don't know how these things are supposed to work, and I'm worried my battery might have any kind of problem and that's why itdoesn't have full capacity anymore, since I've been using it for only a month.
Also, sometimes it takes a little while to shut down. It usually takes 2 seconds, but sometimes it takes longer, maybe 20 seconds (first the screen turn white, then the loading icon appears and then it finally shuts down). Is this normal too for macbook airs?
Thanks for the help!

Those are only averages, for purposes of the battery 97 98 99 and 100 are the 'same thing'........theyre all estimates.
Normal on shut down, sometimes you can see a few seconds, sometimes 10, 15 seconds shut down.....depends on what and HOW much its shutting down before poweroff.   Normal.
ON BATTERY USE:
Keep it plugged in when near a socket so you keep the charging cycles down on your LiPo (lithium polymer) cells / battery, but not plugged in all the time. When not being used for several hours, turn it off.
http://www.apple.com/batteries/notebooks.html
"Apple does not recommend leaving your portable plugged in all the time."
General rule to remember of Lithium batteries is:
Never drain them LOW & dont always/often store them HIGH
While cycle count is commonly seen to be the “miles” on your Lithium Ion pack cell in your Macbook, which they are, this distinction is not a fine line at all, and it is a big misconception to “count charge cycles”
*A person who has, for example, 300 charge cycles on their battery and is recharging at say 50-60% remaining of a 100% charge has better battery usage and care than another person who has 300 charge cycles at say 15% remaining on a 100% charge.
DoD (depth of discharge) is far more important on the wear and tear on your Macbook battery than any mere charge cycle count. *There is no set “mile” or wear from a charge cycle in general OR in specific.    As such, contrary to popular conception, counting cycles is not conclusive whatsoever, rather the amount of deep DoD on an averaged scale of its use and charging conditions.
                          (as a very rough analogy would be 20,000 hard miles put on a car vs. 80,000 good miles being something similar)
*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
*However if you don’t plan on using it for a few hours, turn it OFF (plugged in or otherwise) ..*You don’t want your Macbook both always plugged in AND in sleep mode       (When portable devices are charging and in the on or sleep position, the current that is drawn through the device is called the parasitic load and will alter the dynamics of charge cycle. Battery manufacturers advise against parasitic loading because it induces mini-cycles.)
Keeping batteries connected to a charger ensures that periodic "top-ups" do very minor but continuous damage to individual cells, hence Apples recommendation above:   “Apple does not recommend leaving your portable plugged in all the time”, …this is because “Li-ion degrades fastest at high state-of-charge”.
                    This is also the same reason new Apple notebooks are packaged with 50% charges and not 100%.
LiPo (lithium polymer, same as in your Macbook) batteries do not need conditioning. However...
A lot of battery experts call the use of Lithium cells the "80% Rule" ...meaning use 80% of the charge or so, then recharge them for longer overall life.
Never let your Macbook go into shutdown and safe mode from loss of power, you can corrupt files that way, and the batteries do not like it.
The only quantified abuse seen to Lithium cells are instances when often the cells are repeatedly drained very low…. key word being "often"
Contrary to what some might say, Lithium 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 don’t take a new car out and speed and rev the engine hard first 100 or so miles.
Proper treatment is still important. Just because LiPo batteries don’t need conditioning in general, does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesn’t need conditioning.
From Apple on batteries:
http://support.apple.com/kb/HT1446
http://www.apple.com/batteries/
Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace

Macbook air 2014 is 2013 mid?

I bought macbook air in russian apple online store 1 month ago. Now I open settings and see that macbook air is mid 2013...
Why is that?
Is it normal?
< Personal Infromation Edited By Host >

Weird - I thought I posted an answer to this already. The i7 model wasn't updated, just the core i5 model so it is indeed a mid 2013 computer.
It's a bad idea to include personal information - like a computer serial number - in your post. I've asked a moderator to edit the post to remove it.

MacBook Pro 15-inch Early 2011 vs MacBook Air 13-inch 2013

Hello. I currently own a MacBook Pro 15-inch, early 2011 model. It has 8 GB of RAM, a quad-core, 2.3 GHz i7 processor, hi-res, anti-glare display, an AMD 6750m and Intel HD 3000. I bought it off of an Apple product store on Ebay about 3 and a half months ago. It was 1,350$. It was in perfect condition when I bought it, and it still is. I'm really into producing music, and I use Reason 6.5. I also do some other small things on my laptop, like word-processing, web-browsing and I bring it to school everyday. I was wandering if I should sell this laptop on Ebay, and buy a brand-new Macbook Air, 13-inch, 2013 model. The laptop is a little thick and heavy, and its battery-life is nothing compared to the MacBook Air. I really value battery-life I would probably upgrade the RAM to 8 gigs, and maybe upgrade the processor to 1.7 GHz, maybe upgrade the SSD to 256, but I might not. I was wandering if this would be a good idea. How much would I be able to sell this laptop for on Ebay? Is the MacBook Air weaker or stronger than the laptop I am using now? Screen real estate is something that matters a lot when using a music program, which is why I initially went for this laptop. Now, since the MacBook Air is smaller, I know that it displays just as much as this laptop does, so I don't think that the screen size would be that big of a problem. I am thinking about saving up for a 27-inch iMac, which would then be my primary machine, but if I were able to buy one, it wouldn't be for awhile. Anyways, Thanks to anybody who can help me!

Is the MacBook Air weaker or stronger than the laptop I am using now
Its stronger in alloy form factor, slim design with only ONE moving part, no HD to crash from mechanical failure of impact etc.
Ive got an Imac and current Air, and owned several Air, the air is the hands down choice for myself and I wouldnt part with it for any amount of money. Also own a couple macbook Pro, new and older one i rebuilt.
Here is an excellent video comparison between the 11” I5 vs. I7 2013 Macbook Air.

Macbook Air:
Only one moving part, ultrafast boot time SSD, the full power of laptop with the weight of an Ipad (close).
Air is the only Mac that has Haswell, 802ac wifi, and incredible 12hr. batt life in 13" I5. HOWEVER NOW the new Pro have 802ac wifi
Recommend buying the Air with 8gig Ram.
Pack around a regular laptop around about 20 days, then an Air, .....after that the standard laptops stays at home.
Only one moving part, the fan. No moving HD heads to crash or moving platters. Runs a LOT cooler than anything else out there (which = durability). Heater is a killer on a scale of 10X over that of accidents.
Also the AIR has far fewer parts to fail inside than a standard laptop. Really only a few replacement parts
The speakers on the Air, contrary to what most people would assume, are much louder than on the macbook Pro.
The Air in general is faster due to the SSD, also if you have a 802ac Router (i.e. Airport Extreme) then the Air over wifi is a LOT faster.
If youre going to be dragging a notebook around campus all the time, the Air makes things a lot more lovely.
The FINAL consideration of course is your application USE, and needs regarding same (see specs and video above)
The new Air, NOW with Mavericks is just 'king of the hill'. Nothing touches it

Screen real estate is something that matters a lot when using a music program, which is why I initially went for this laptop. Now, since the MacBook Air is smaller, I know that it displays just as much as this laptop does, so I don't think that the screen size would be that big of a problem. I am thinking about saving up for a 27-inch iMac, which would then be my primary machine, but if I were able to buy one, it wouldn't be for awhile. Anyways, Thanks to anybody who can help me!

Nice to see you again.
The macbook Air is 'stronger' than the Pro only in terms of containing MUCH fewer parts, far less to fault, easier to repair
both have unibody aluminum alloy frames.

New MacBook Air 11 inch, 2013, Kernal_task running 300% constantly

I have just purchased a brand new MacBook Air 11 inch, 2013.
I noticed that the fan was running constantly when I booted up and have tracked it through the activity monitor to the Kernal_task which is eating up 300% on the CPU. I have no thrid party software or apps installed. It's brand new out of the box and the only thing that has been done is install the Mavericks updates as instructed by the apple update software.
And yet the Kernal_task still runs at 300% and the fan grinds on constantly regardless?!?
Is there anyway to fix this? Or have I got a dud model. It seems to be very strange for a brand new Mac to be like this. The fan and the Kernal_task as chewing through the battery and making the whole point of purching this Macbook Air a bit pointless.
Is there anyway to kill the Kernal_task without bricking my Mac?
Cheers,
S

Take it back for replacement since it's in warranty.
