MacBook Air 11 '' Early 2015: normal sleep/standby consumption?

Hello

I can't help thinking that the power consumption of my MacBook Air 11 '' (early 2015) while "asleep" has increased lately - battery loses about 20% in 24 hours of sleep. "

So, here's my question: is a loss of battery charge about 1% by standard time?

I should add that I can see log files that the appliance has been in "Deep sleep" during sleep, as you can see here:

05.01.16 21:15:34, 000 kernel [0]: ARPT: 7953.437734: IOPMPowerSource information: onWake, SleepType: deep Idle, "ExternalConnected": No, "TimeRemaining": 4370.

I've already changed parameter of power management that the device should enter mode standby after 4 minutes of sleep (see below), which he seems not to do (always).

In the terminal, the command of g - pmset we get the following results:

Active profile:

Battery - 1 power *.

Power supply - 1

In use:

standbydelay 240

Watch 1

halfdim 1

hibernatefile/var/vm/drag

PowerNap 0

gpuswitch 2

disksleep 10

sleep 2 (sleep prevented by AddressBookSourceSync)

autopoweroffdelay 14400

hibernatemode 3

autopoweroff 1

ttyskeepawake 1

displaysleep 2

acwake 0

lidwake 1

BTW: I do not think that the entry "prevented... sleep." "really means the unit can not sleep - he lay in mode 'deep sleep '.

Thanks for the ideas.

Thank you all for the many responses (SCNR)

Just to give me a follow-up (perhaps this helps someone in the future):

After a thorough analysis of the pmset g rawlog and console output that I discovered that my MacBook Air just don't go 'Deep rest' in mode 'Sleep' after the designated 'standbydelay'. Deleting the file drag (var/vm/drag) has not helped. What helped, however, was a reinstall of Mac OS X recovery (without removing the hard drive).

Since then, consumtion of power during the sleep returned to a much better behavior: during the first three hours of sleep, consumption is about 3%. Subsequently, the system performs a wake of maintenance for switch in the standby mode, and after that which consumes almost no more energy. So, after 24 hours, the overall loss of battery charge are still 3%.

I'm happy again.

    Hello everyone.

    I currently own a Chromebook, product that I hope, I sell to help me get the MacBook Air 13. The purpose of the switch is the requirement for me to have a computer (with an operating system in its own right) that I can use for computer science stuff. However, I'm worried about the MacBook Air 13 (Early 2015; the 8 GB of RAM, 128 GB SSD model) is how obsolete, and its durability. I not looking for a laptop that will last me a year and performance degradation that are present or any downgrade of the user experience. I expect a computer that will give me at least 3 years of service and still work without any problems (excluding the damage caused to the user, but assume that I am a responsible person).

    Any kind of help is appreciated.

    Thanks in advance,

    We have no way of knowing exactly what you have tried that doesn't work unless you tell us. A flashing question mark boot means that your Mac is unable to locate a startup disk to boot from.

    If you haven't tried... start your Mac holding the key Option. That should launch the boot window manager have been, you can select the startup disk, and then click on restart.

    If this does not help, you will need to take the Mac for the service.

  • Spots on the screen from macbook pro 13 early 2015

    I am from Nepal and bought Macbook pro 13 Futureworld last year. I noticed stains and spots on Macbook pro early 2015. Its the apple care warranty. I would like to know if it is covered by the apple care warranty or not. With this question, I also think questions of wifi signal that falls and has bad reception. Windows 10 Hp431 works very well, Iphone5 too connects well to the router and on speedtest shows better resistance than that of the macbook pro 13.

  • Bluetooth SPP very slow on the macbook 13 retina early 2015

    I use the Bluetooth SPP profile much download code the arduino-based robots in my classes. This used to work fine on a Macbook (13-inch late 2011) unibody + Yosemite, but since I have upgraded to a Macbook 13 beginning 2015 retina, transfers are > 20 x slower with Bluetooth Explorer showing many broadcasts, although the RSSI is very high, and both devices are close together.

    I have already filed a bug report to bugreport.apple.com (15 days ago), still no response whatsoever.

    It happens to someone else? That is to say is - this just my computer that is faulty? It would also be useful if the computer even with an older version of OS X (Yosemite) working for someone else.

    This is a screenshot of a transmission with the internal Bluetooth adapter to 115200 bps. Transfer rate should be, well... aound 11520 bytes/s. I get 550 B/s instead, a LOT of broadcasts:

    And an another screenshot using an external USB bluetooth adapter (noname brand) (~ 12 Kbps good speed and 0% retrasmissions).

    TL; DR: Flow slow Bluetooth SPP has been fixed in 10.11.4.

    Answer...

    I reported this through http://bugreport.apple.com/ jan-9, then the mar - 21, I was warned that the next version should fix. The same day, I upgraded to 10.11.4 and it is indeed fixed. I get normal speeds (12 KB/s for a 115,2 Kbps link), see screenshot.

    After a few months, I thought that this would never get the attention of Apple. Then... Thank you very much!!!

  • MacBook Pro battery (early 2015)

    Before you start - Yes, I already read the articles provided by Apple about how I should take care of the battery of my camera. My only concern is now is it nice to put on 100% standby and plugged? I don't use it much everyday, just minimum of probably around 2-3 hours and 5-6 vertices. What I'm doing lately is unplug the charger until I put on standby then plugged while waking up, I plugged it in while I use it then unplug the charger again before you put it to sleep and so on and so forth. Is it safe? I'm doing it correctly? Thank you.

    You can leave the MBP connected to the charger essentially all the time with damage to the battery, because OSX control the load and will not allow the battery to be overcharged.

    HOWEVER, at least once a month, use the MBP with battery only on 40% charge level.  Lithium-ion batteries require periodic "exercise" to maintain long battery life.

    The other fundamental rule is to avoid draining the battery until it stops the MBP.  That will shorten the battery life.

    Ciao.

  • Small vibrations cause damage to Macbook Air?

    MacBook Air 13 "early 2015. When I work on my mac on different tables, a small movement can cause a small table vibration that makes Macbook screen, shake (very little, but when even he shakes). It is not very noticeable, but I was wondering if these vibrations can damage the hinges of the Macbook and affect the ability to hold the screen in the future. I also noticed that the Macbook Pro hinges are more difficult, than Air (probably due to the fineness of the Air).

    Any movement causes stress and eventually lead to the failure of the given element.  It's a question of degree and frequency.  According to your description. continue to use your MBA and ignore this issue.  It is to small to worry.

  • Help! My Macbook Air has a high memory pressure.

    Product: Macbook Air in early 2015

    Plug-

    256 GB of flash storage

    1.6 GHz processor

    4 GB memory

    OS X Yosemite - Version 10.10.5

    A few weeks memory of my Macbook Air pressure continued to increase, most of the time he was in the green zone, but it has been several times that I had the pressure of memory to be in the yellow box with a few tabs in Google Chrome. In addition, the Kernel_Task continues to rise as it was around 380-390 MB a few weeks ago and now he's moved more than 500 MB. I tried to restart and stop the computer several times as an attempt to decrease the Kernel_Task and even thought that the memory pressure is high, the CPU doesn't have a lot of problems, because it is essentially inactive between 65 and 80 percent.

    What it looks like without all the eleven (shown) Google Chrome processes running? You should never see Swap used, and that tells me that you are using too many applications for your 4 GB memory available on your machine. With this RAM limited, you have to be very selective of what applications and browser tabs are open (you use) quit everything.
