MacBook Air 2012 Severe Battery Drains While Sleeping

Hi there,
This isn't any new but I've looked through all posts I could.
I got a refurbished MacBook Air 2012 in July. In the first 2 weeks it worked fine (or I was noticed).
Then I noticed the battery drains fast while the system sleeps.
I have done tests in the past weeks; almost 20% of battery drain after slept a day.
I have tried everything I could: turn off PowerNap, no wake from BT devices, erase and reinstall OS
None of above helped.
I have tried to modify hibernatemode to 25 and it worked ok; 2% of battery dropped after 12 hours.
I took this to Apple in Taiwan and they told me they couldn't do anything about it because they think it's software conflicts which does't really have a solution but wait for OS updates. They did run a diagnostic and everything turns out to be fine.
I just did reinstall the OS again and I'll see whats going on tomorrow morning.
If still not getting better I will just use hibernatemode 25.
Anything recommandation is more than welcome.
Thanks.
My OS version is 10.8.3.

Tried hibernatemode to 25 and still not helpful at all.
Battery drained 8% after 10 hours of sleep while mode 25 should put my macbook air into deep sleep and consume very minimal power.

Battery drains while sleeping after RAM upgrade

Installed 16 GB of RAM and a Hybrid/SSD 1 TB internal HD on MacBook Pro 15" mid 2012 and now the battery drains while the computer is in sleep mode, about 1-3 % per hour. Before the RAM upgrade (stock 4 GB of RAM) there was no noticeable battery drain, so I assume it has to do with the upgrade. I read that it takes more power to maintain 16 GB of RAM during sleep, so my questions are as follows:
Is 1-3% per hour normal?
Will resetting the SMC help the issue?
Does the Hybrid HD have anything to do with this?
I am not too happy about the battery drain as it happens that I don't use my laptop for some time and prior to the upgrade the loss of battery charge was not an issue at all. Is this the price I have to pay for maxing out my RAM or is there a way (resets, settings, etc) to reduce the amount of battery loss
Thanks for your input.

Hi everybody. I have the same question. I have a macbook unibody late 2008. I have recently upgraded the OS to Yosemite. In order to have a smoother functioning of the system I have immediately replaced my original 2Gb (1+1) RAM with 8 Gb (4+4). Since then, I have noticed a dramatic reduction of my battery charge during sleep mode. Now after 8 hours of sleep it goes from 100% to around 65% (before it was 95%). Is it a natural consequence of having installed a larger RAM or there could be anything wrong with my settings?
I have read a couple of articles about standby mode and standbydelay setting but this does not apply to my model of macbook.
Here is my pmset -g result:
Active Profiles:
Battery Power        -1*
AC Power        -1
Currently in use:

Thanks a lot for any comment / suggestion /hint.

MacBook Air Mid-2013 Battery Draining FAST (about 5-6 hours at best)

I have been having problems with my Mac's battery draining very fast even on light usage. Simply using Safari will drain my battery in 5 to 6 hours, when my laptop would last the stated 12+ hours before when browsing the internet. I followed these steps yesterday...
Reset com.apple.finder.plist, com.apple.sidebarlists.plist and com.apple.desktop.plist
- Open a new finder window
- Choose Go > Go to folder. Your destination is ~/Library/Preferences
- Locate com.apple.finder.plist and rename it to com.apple.finder_backup.plist
- Locate com.apple.sidebarlists.plist and rename it tocom.apple.sidebarlists_backup.plist
- Do the same for com.apple.desktop.plist. Note: This file was missing in my folder. If so: nevermind.
- Open Terminal and type: killall Dock
Reset your SMC:
- shut down your system
- plug in the magsafe
- hold down shift+ctrl+alt+power for a second, then release. Your magsafe should blink
- do this three times
Reset PRAM:
- turn on your mbp and hold down alt+cmd+p+r immediately
- hold down the keys until you hear the startup sound the second time
- release the keys and let the MBP boot.
Give your system some time to adjust to the changes: after a while it should show you a much increased battery time.
...but to no avail, it didn't have any effect on my machine. I'm not sure what to do. :'( Activity monitor shows Safari as having a "10.7 average energy impact" (I don't know what that means in all honesty) and is the highest consumer on the list, with Dropbox being number two on the list saying the average is 1.9 at the moment. I quit background applications so I know that's not an issue — I don't know where to go from here. Also, my battery max/health is 6909 at 97% health, so I do know it's getting a near-full charge. I miss having 12+ hours of battery as that's what I bought this for. Should I go to the Genius Bar and see what they can do?

Hi hawknelson24,
It sounds like you have been on the right track. If you are looking for more options for troubleshooting your battery issue before potentially taking your Air in for service, you may find the following article helpful:

Automatically sleeping a MacBook Air prior to battery reaching zero..?

Hi, does anyone know if there is a way to automatically 'sleep' a MacBook Air before the battery runs out?
I'm usually pretty good at plugging it back into the mains before it 'dies' but twice recently I have missed the warning for a low battery and it has 'died'.
There must be a setting or an app out there that will 'sleep' the laptop when the battery gets to a specified battery percentage or time remaining.
Btw, I have a late 2010 13" MacBook Air running Snow Leopard.

Tried hibernatemode to 25 and still not helpful at all.
Battery drained 8% after 10 hours of sleep while mode 25 should put my macbook air into deep sleep and consume very minimal power.

Macbook air energy usage - battery runs down whilst sleeping

I have a July 2013 Macbook Air and the battery seems to be running down quickly (more so while it is sleeping, the usage when awake seems to go down at expected rate).
I have taken it to apple genius bar who said the battery was fine and did a fresh install of 10.9.2 (I then restored my time machine backup). They ran a diagnostic and said battery was fine.
There are no big active processes under activity monitor and power nap functionalies are disabled.
The battery runs down over the course of one day if asleep and just now it dropped by 10% in an hour while asleep (closing the lid or going to apple and then sleep makes no difference).
It did seem to start suspicously around the time I upgraded to Mavericks so I feel it's a software issue....
Any ideas?!
Thanks so much
Alexis

Tami ...
I turned off any automatic updating, stopped Sophos Antivirus from on-demand scanning.
Regardless of turning off updating ..... a/v software on Mac can cause a litany of problems.
Uninstall the Sophos a/v software > Removing Sophos Anti-Virus for Mac OS
Then restart your Mac to see if it makes a difference.

Does leaving macbook air on all the time (while plugged in) to download torrents degrade battery life?

Does leaving macbook air on all the time (while plugged in) to download torrents degrade battery life?

You have a lot of things going on here...you are keeping the Air plugged in all the time, you should run on the battery periodically to give it some exercise, you are keeping it on all the time which may be keeping it under constant or near constant load, and you are doing all of that to download pirated content, for which you will get no help on here.

Pricing starts at US$999 at the Apple Store:
Current retail cost is $950 on same.
And if shes a student, she gets a big discount, POSSIBLY making the cost difference 0 $
That choice is a subjective one. However since the 11" base AIR is only $950, youre talking $110
For a $110 difference, the answer is absolutely unquestionably YES.
For $110 youre getting an awfully lot more,...... faster,... MUCH longer batt. life,... 802ac wifi,.. cooler running.
$110 cant buy that kind of "upgrade" anywhere, making the cost difference absolutely worth it.
Again, your choice.

Severe battery drain with iOS 8.1.2

I am having severe battery drain issues with iOS 8.1.2 with all my iOS devices (iPhone 6, iPhone 5s, iPad Mini Retina, iPad Air). I can have my device in DND mode overnight with 100% battery, then the following morning I will wake up to find my device down to 20%. The battery usage graph shows nothing abnormal, just very rapid battery drain. What gives?! I saw a couple other threads mentioning this issue. I have attempted Network Reset and verifying Bluetooth is off, but this is just crazy. Anyone else get a resolution on this or experience this after iOS 8.1.2?

tldr; Check the secd process on your Mac. If it is consuming greater than 50MB of memory...turn off Keychain sync on ALL your devices.
The Full Story
The last few months I've had instances where my iPhone would start getting really hot in my pocket, and the battery would drain at 3x the speed. After much research I also discovered that a process on my Mac (secd) had a vicious memory leak and that single process was consuming 13GB of memory and paging thousands of console messages. After discovering that the process was related to Keychain sync, I disabled keychain sync across all 5 of my devices. Immediately, the battery life on my iPhone was restored to normal.
After I reenabled Keychain sync across all my devices, everything would run fine for a while, but after a few weeks, the problem would resurface. And I would repeat the process of turning it off on all my devices, to effectively reset the iCloud keychain data.
Anyway, Apple does need to fix this, as it affects performance on both OSX and iOS.

Macbook air 2012 Shutdown problem!!

Hi all! I have a problem with my Macbook air 2012. OS 10.9.5.
This morning my sound were not working so i rebooted my machine. And here the problems start. My macbook now goes into sleep mode after 5 Seconds! And when it does so, i have to unplug/plug magsafe to get it back on. Then another 5 seconds before it shuts down again. I have tried SMC and PRAM resets. I am not able to do a erase+reinstall because the Internett is lost every 5 seconds due to the black screen. However when i pressed OPTION+ON button to get into the reboot menu the screen didnt shut down. Until I clicked on Recovery, then it started again. So, has anyone had the same problem? Any solutions? Is there a connection to the no-working sound? Help is extremely appriciated! :-)
I can still charge my phone while the screen goes black, if thats helpful for you guys.

It will be longer for the first shutdown, but should be faster thereafter. But then how much longer is it? I have a couple systems where it takes at least 15 seconds to shutdown.

Macbook Pro running slow/battery drains when closed

Hi!
I have a Macbook Pro 13-inch, mid-2012 running OS X 10.9. It recently started running extremley slow and the spinning ball pops up all the time when I try to do basically anything, but mostly when I try to do more than one thing at a time. Sometimes it will run normal, but then slow up. The spinning ball also pops up basically everytime that I try to play a video or anything like that. The adobe flash plugin also seems to crash a lot.
Also, when it is closed, it becomes very warm and the battery drains while it is closed. It seems like it doesn't really turn off when it closes.
Anyone know what could be causing this?
Thanks!

I ended up having to take it in. Turned out there was a connection to the hard drive that was loose or something. I took it to a store in my city that specializes in macs so I didn't have to spend a fortune. Otherwise, I had someone else look at it and they said that it could have been from when I updated my computer, that something didn't download properly- which has been an issue in some computers.

Problems with my external USB 3.0 (Toshiba) hard drive and Macbook Air 2012

I can't seem to get any help on this from Apple and I am tired of ti I have a new Macbook Air 2012 model and have several Toshiba external USB 3.0 drives. I did the Mountain Lion App Store 10.8.2 update and all of a sudden non of my drives are mountable or accessible. I've been in IT 16 years and have never seen anything like this. The drives are physically fine and I can see the mapped partitions on a Windows 7 machine just fine and even use HFS Explorer to view the directory structures. The data on these drives is extremely important to not only me, but also the DoD who I am working with on a major project. Now I can't get to my documents to edit them or pull down the virtual machines I setup for my labs.
I've done all sorts of research and googled myself to death. I even foudn the "missing because Apple pulled" 2.0 update to try and fix this issue. Whatever was done with ML 10.8.2 on these notebooks renders the USB ports useless. Does anyone have a solution to getting these drives to mount?

I have the same issue.
I have two disks HDTC720XK3C1 (Portable Toshiba Hard Disk, USB 3.0 + 2.0, 2.0 TB). Purchased on the same date and same model. One inexplicably stopped working.
When i connect the drive, the systems show an message that say:
"You need format the drive <x> before can you use it
Do you want to format it"
I attach the two pictures with the screen error and disk managment.
Question for the group: These devices seem not very reliable ? this type of error the warranty covers? Sugestions ?
i think, that a backup tool should be secure. This is the 7th time I use it and the data is completely lost. Opinions?

I'm looking for a laptop that will last me a couple of years which is why I'm upgrading to SSD without losing performance. I usually game on my Mac so I want a laptop to handle that, handle programs in the background and writing or reading without losing speed, I also need a laptop that has fast boot time.
I will be using the laptop mainly for school and running programs such as iWork and mircrosoft office as well as websurfing and video streaming thanks for any advice.

I hope others pipe in with their comments, but the first suggestion is to visit your local Apple Store and try out the units. Trying them out can make a difference in your decision.
This is how I'd try to make sense of this:
MBP 13 2012:
Solid all-purpose portable at a decent price, and even has a 240GB SSD. If you don't load it with tons to videos, this will more than fit your needs as a student and websurfer. A little heavier than the others here, but it's a solid package that's stable. Great if you need to use the CD/DVD.
MBA 13 2012:
Also good, similar specs, notably lighter. Notes are easy to take, and easier to carry on long campus treks. If you're not near a power source, the battery life may be a concern. If you need a CD/DVD, you can connect it when you need it - but it's extra. Servicing a MBA is more difficult.
MBR 15 2012:
Beautiful display, packed with performance. No DVD/CD drive, NVIDIA performance is unproven, kind of pricey, the first generation of a device; it's going to get better over time. Can't be serviced in any way by the user; the Apple Store is your only option. Now's not the best time to get the MBR.
MBR 13 2012:
Same comments.
I'd say the MBA is a good pick. Few moving parts, therefore more reliability. Low heat. You can always attach a CD/DVD drive via USB. Intel Graphics is solid; no problems there. Plenty of capacity for your needs. And the display is bright. MBA 13 or 11, IMO.

Does the MacBook Air 2012 supports SDXC Cards?

Does the MacBook Air 2012 supports SDXC Cards?
Thx

Hi! How are you? The reason why I'm here is to find out more about SDXC support/compatibility info on the macbook air 2012 and how to fix this nagging issue if it's fixable.
I had just bought a Sandisk extreme pro 64GB rated at 95mb/s for my Nikon DSLR. Unfortunately, MBA struggles to detect or mount my card, after a few sweats, it would mount, but then very slow to process and preview the images as "Thumbnail preview". Then, after a few more sweats, you can scroll through the thumbnails smoothly.
Streaming HD videos straight from the SD Slot is butcher chopping the beef. Video lags, stutters, chops, in otherwords, USELESS and a pain in the neck. So you just want to copy all the files to your macbook, and play from there. Copying files from SDXC to my macbook takes forever; writing is also another issue that take much more than forever!
I have a top of the line macbook air 2012 (i7, 8GB, 512) and I always thought it's a versatile reliable computer but now I'm very disappointed. On the other hand, doing the same things on my macbook pro 2010 is seamless. I also tested on my windows 8 desktop to be flawless as well.
Therefore, the memory card is not the problem. It's macbook air's sd slot that's a failure. I never thought spending $2,199 for a super computer would make me stress like this. In addition, the magsafe 2 is another failure in design. It always disconnects just by moving my macbook air from one spot of the table to another. Having it charged while on my lap gets on my nerves when it keeps getting disconnected! I hate Apple for doing this. If only there was a Windows notebook that surpasses Apple's design, I would never EVER buy Apple products EVER again.
