MacBook 2016 Battery Concerns...

    I have been on the official forum for MacBook over at apple communities and there isn't anyone that can answer this question OR doesn't really monitor that forum, so let me try it here.

    I have a MacBook (Retina, 12-inch, Early 2016),
    1.2 GHz Intel Core m5

    In the past, I've owned a MacAir, the last one was 2014 model. I used to close that machine and 12 hours later, sometimes 24 hours later, I would come back and lose no battery or maybe 1% battery over that time period.

    With this machine, it is the opposite.

    I close ALL my programs, close the lid, and 12 hours later, I go from 100% to 89% battery. I am lost. I do not know why this is continuing to happen to my machine.

    The ONLY applications I have added to it are:

    Microsoft Office

    But I have disabled all auto start ups for all of these add ons. I have also run an EtreCheck on my machine and will attach to this post. Any comments or suggestions on what is happening here? Something tells me it is Chrome or Office, but I am not 100% sure at this point.

    Thank you

    Is PowerNap enabled? Put hard disks to sleep where possible enabled? Do you have any peripherals plugged in whilst it's on sleep mode?

    It sounds like something is preventing it from entering Standby Mode.

    If you have any external devices attached it can prevent your Mac from entering Standby Mode and the battery will drain faster while asleep. Try the steps at the bottom of this link.

    PowerNap is off..I turned all options off that would allow it to wake up periodically

    Forgive me for my ignorance...I am fairly new at this on Apple...Can you describe how I go about running that? Thanks
    --- Post Merged, Jul 21, 2016 ---
    Well the only thing I have that might continually wake up my Mac is notifications. So I did the Do Not Disturb option for when I am normally home to see if that works.

    Outside of that I don't have any external devices at all attached.

    Somehow I think this has to do with my home wifi network affecting this. Either via a router issue or the fact I have to wifi network...regular and 5G..wondering if it is constantly polling between the 2?

    Ok...I have confirmed what I thought.

    I turned my Wifi Off, closed lid, and in the AM, 11 hours later, my MacBook lost 0% battery...still had 100%

    2 Nights ago, I left Wifi ON, and as it always has done, it dropped 11% in 10 hours, again.

    Additionally, I does NOT do this when I travel away from home. Now I am wondering if this is my home network or router? It is a new Wifi Router provided by Verizon FIOS that supports regular and 5G wifi. Both appear on the list every time I boot up.

    Question now is, where do I go from here and has anyone else had this issue with a router?

    So it is 100% the Wifi. Having turned WIFI off for 4 consecutive nights, ZERO battery drain overnight when Mac is sleeping. When on the road, I have left Wifi ON and again, no battery drain.

    So this most likely points to a router router works fine, but perhaps something is causing it to wake up and connect and disconnect?

    I also have regular wifi and 5g wifi, both have the same passwords (they have to).

    It's Verizon FIOS 100mbps and wifi extender as well.

    Any suggestions? Anyone else have the same issue with router? I have researched it and cannot find anything definitive on the subject.

    I have a Verizon FIOS Router and it hated my stuff (iPads, iPhones, Macbooks) so I got a Netgear N600 and have been happy with it ever since (5 years now). I turned off WiFi for the FIOS router and use it as a go-in-between to the FIOS box. I have no battery usage overnight for my devices (macbook air).

    Could it be power nap? Try disabling that one.

    When I first bought my 2015 MB, I was having the same issues. This was the thread that solved the problem for me:

    I set my computer to only wait 5 minutes before entering standby. There is a slightly longer delay to wake when I open the lid but barely any battery drain when closed. When I upgraded to El Capitan, I had the same issue again and had to apply the terminal command once more. Perhaps it will work for you?

    I disabled that a while back with no change
    --- Post Merged, Jul 29, 2016 ---
    So you used this:

    sudo pmset -b standby delay 3600

  12. bluewooster macrumors member

    Jul 18, 2007
    Yes - I actually set my timeout for 5 minutes (sudo pmset -b standby delay 300) but 1 hour (3600) is probably helpful as well. Like I say, there is a slightly longer delay when opening the lid but not unreasonable by any means and my battery drain when the lid is shut (with the wifi still on) is very negligible.

    Well, I set it as well, unplugged at 100%, opened 11 hours later, and I'm down another 9% in 11 hours!!! So, I guess that isn;t the issue. I would have to guess that it's something to do with my router. I mean, I shut off wifi and do the test and there's zero drop in battery life. When I travel, and leave wifi on, same thing, no drop in battery overnight.

    Try turning off your home router. Than connect to your phones hotspot via wifi before going to bed. If the prob persists than its not your home wifi.
