Last night, I've switched of my WiFi on my mac before I've put the mac in sleep mode. This resolved the problem of fast battery drain (only 2% during 10h of sleep mode). The log-file was still pretty messy, with a lot of activity. But the command (syslog |grep -i "Wake reason") gave this:

A RTC (alarm) every 2 hours. Please note that I've no wake-up schedule, wake from network is unchecked and powernap is also unchecked. I've also disabled any sharing service.

How can I resolve this problem? I want to use sleep mode without disabling WiFi and without losing 20% of battery over night...

EDIT: It seems to me that Apple has fixed the battery drain (in sleep mode) in macOS Sierra (10.12).

When I look in my logs, I can see that it connects to 17.143.161.166 on port 5223 and to 17.110.229.212 on port 5223. These are IP-addresses owend by Apple Inc. located in California (according to ipinfo.io). I don't know why this happens... – Kevin De Koninck Nov 29 '15 at 10:49

I didn't found the exact cause of the problem, but I did found a solution which will avoid massive battery drains in sleep mode. The solution was to disable Airport (WiFi) when the Macbook was sleeping.

I used SleepWatcher v2.2 (http://www.bernhard-baehr.de) to run 2 scripts at wake and sleep interrupts. When the macbook goes to sleep, I execute the following command to disable WiFi:

/usr/sbin/networksetup setairportpower en0 off

When the Macbook wakes up again, I enable WiFi again:

/usr/sbin/networksetup setairportpower en0 on

You can download a script that installs SleepWatcher and the scripts at https://github.com/Kevin-De-Koninck/PleaseSleep .

Please note that in the original question of mine I said that I didn't want to disable WiFi constantly when putting the Mac to sleep. This solution does the same, but automatically, which makes it a good solution for the battery drain.


The sleep script:

#! /bin/bash   
echo `date` "Sleeping" >> /tmp/sleep.log  
/usr/sbin/networksetup setairportpower en0 off  
echo `date` `/usr/sbin/networksetup getairportpower en0` >> /tmp/sleep.log  

The wake script:

#! /bin/bash    
echo `date` "Waking up" >> /tmp/sleep.log  
sleep 7  
/usr/sbin/networksetup setairportpower en0 on  
echo `date` `/usr/sbin/networksetup getairportpower en0` >> /tmp/sleep.log

I wonder, when Apple is going to fix that. I had the same problem since some update, your solution fixed it for me, thanks, but I'd love to be able to just pop my laptop open and start working, not wait a few seconds for WiFi to warm up. – dotz Jul 24 at 12:16
    
I changed the wake up time from 7 seconds to about 3 seconds. You can experiment with the time, maybe it isn't necessary, but I've included it just to be sure. I've also updated the sleep and wakeup scripts on my github (added intelligent switching). Personally I don't think Apple is going to fix this. I wonder if they even now about this bug... – Kevin De Koninck Jul 25 at 13:12
    
Sierra seems to fix this for me, past few hours I disabled your scripts and I still have some battery left. Sometimes I had useable (known) WiFi network in range, sometimes I didn't. What is your experience after upgrading to Sierra? – dotz Sep 22 at 12:11
    
I disabled my script yesterday and charged my macbook to 100% and then I disconnected the power cable. I've put it to sleep at 00:25 AM and at 4:45 PM, I started my macbook again and it still had 100% battery left... So yes, I think Sierra has fixed this for me too. Thanks for pointing out! – Kevin De Koninck Sep 25 at 14:47
    
Thanks for your scripts, which saved my ass for last 6 months or so. I suggest you update your original question somehow. There is almost no information on the net about this issue. Also... it may be re-introduced after some updates, because why not... – dotz Sep 25 at 19:33

Does your machine support Power Nap? As I understand, this function causes the computer to wake at certain intervals to do things like check email but still keeps power use to a minimum. I'm not sure if it uses an RTC alarm to do this or not. https://support.apple.com/en-us/HT204032

It does support Power Nap, but I've disabled it in Energy Saver Settings. When I look in my logs, I can see that it connects to 17.143.161.166 on port 5223. This is an IP-address owend by Apple Inc. located in California (according to ipinfo.io. – Kevin De Koninck Nov 29 '15 at 10:46

Here is a better way to toggle your wifi on/off with only one command

networksetup -getairportpower en0 | grep "On" && networksetup -setairportpower en0 off || networksetup -setairportpower en0 on

And you can also create a shortcut to running the command

1. Start Automator, and create a new Service.

2. Set "Service receives selected: to "no input" in "any application".

3. Add an action named "Run Shell Script". It's in the Utilities section of the Actions Library.

4. Insert the bash command you want into the text box and test run it  using the Run button (top right). It should do whatever the script does (off, on or toggle), and there should be green ticks below the Action.

5. Save it, giving it a service name you can remember.

6. Go to System Preferences -> Keyboard, and go to the Shortcuts tab

7. Go to the Services section, and scroll down to General - you should find your service there. If you select the line, you can click "add shortcut" and give it a keyboard shortcut.
