Power drain due to wifi while sleep

Power drain due to wifi while sleep

Hi guys,

My macbook is draining too much over night (about 6 percent) compared to my mid-2014 macbook airs (about 1 percent over night).

Checking my router's log the macbook stays connected all the time. Powernap is off. Besides turning off wifi manually every time before I go to sleep, is there a way to restrict this?

Here are my pmset settings:

Active Profiles:

Battery Power -1*

AC Power 2

Currently in use:

standbydelay 10800

standby 1

halfdim 1

hibernatefile /var/vm/sleepimage

darkwakes 0

gpuswitch 2

disksleep 10

sleep 15

autopoweroffdelay 14400

hibernatemode 3

autopoweroff 1

ttyskeepawake 1

displaysleep 15

acwake 0

lidwake 1

MacBook, OS X Yosemite (10.10.3)

just talked to apple support, even had the tier 2 guy calling me.

it basically boils down to this:

it may be a bug, or not. no one at apple support seems to know. there may be a fix in a future update, or not. the tier 2 support did not seem to care at all but oh well. I am used to Microsoft customer support so his attitude doesn't impress me. I'll be returning it.

The wifi is turned off during sleep. This would be actual sleep and not just display sleep.

When you wake it up, you should be able to see the wifi reconnecting for a second or two.

Have you updated to 10.10.4, your status shows 10.10.3?

hi lanny, I can confirm wifi is not off while sleeping. I can see it constantly connected on my router display. I am on 10.10.4.

I know what you mean, my macbook air behaves this way. Obviously I like that. And, I can not see my air while it is in sleep mode on my router interface.

Okay, I see what you mean. I also have a new 12" MacBook, it replaced a MacBook Air that died from a coffee spill.

Also tried SMC resetting.

It may be only applicable to 12" Retina MacBooks. Could be kind of a clumsy fix to the problem of not reliably reconnecting to wifi after coming out of sleep, don't disconnect.

sorry to hear about your coffee accident!

thanks for sharing your pmset settings. Don't see any difference that could explain any of this.

That was the PMset for the MacBook, the MacBook Air is no longer available and was running Snow Leopard.
