Mojave: HUGE battery drain during sleep

Okay ... I watched the issue a bit longer and I searched a lot of newsgroup all across the internet.

I also scanned my powerlog and saw that the machine regularly wakes and does quite a lot where after every wake the battery percentage goes down about 2% (sometimes even 4%). I decided to set the hibernate mode to 25 via pmset command and now the battery loss is much much lower. For me a valuable change that extends battery life to a longer time.

For me it works now much better although it is not perfect ... I still received no help from Apple on this and helped myself with this workaround ... not perfect, but better.

I'm also have this exact same problem.

Contacted apple support twice, and after all the usual resets I waited for 3 days to test the procedures and nothing has changed.

Left laptop last night with 100% charge, disconnected the power and put it to sleep. Woke up this morning with 65% charge.

Contacted apple support again and after a bunch of nonsense standard procedures, they are pushing for me to send my laptop for a service centre (at a cost) as they have "diagnosed" out of nowhere that there's a hardware problem with my MacBook pro.

Useless trying to explain that this was not happening last week whilst still running on High Sierra, and for the record has never happened at all.

Apple is refusing to look into this problem even with all the complains al over the internet.

Some people have had this problem, but most people don't.

I can't remember the details, but there are solutions for those afflicted, that have been offered on other threads.

Turning off power nap is the first and obvious thing to do, but it is not enough.

AFAICR, there were some processes that prevented some macs to sleep properly - because, let's face it, if the macs were indeed sleeping they would not waste away that much power.

In reality it is NOT accurate to say that the affected macs drain battery during sleep, but rather that something wakes then up and this drains the battery.

I think it is Mojave but with a brand new MacBook I don't have the option to downgrade to Sierra. My MacBook Air 2014 is on Sierra and did not have any problems. (Although it is dying now after 5 years which is why I am buying a new one.)

Please report this as bug to Apple. The more of us, is better.

Did anyone installed macOS Catalina Beta? Maybe in Catalina it is fixed. I reported a bug with huge battery drain but they did not respond.

Ehh...I am going to ping them until they will fix it.

I tried with sudo pmset hibernatemode 25 but the MacBook still wakes up from sleep. Last night it woke 10 times over a 16 hour period. So for me it's not solved by setting hibernatemode to 25 and it seems to influence how connected USB drives are handled when going to sleep. Before hibernatemode 25 I didn't have any issues closing my MacBook with a connected USB drive. But now when I open the MacBook I get the "Disk not ejected properly" warning.

I'll try also with sudo pmset -b tcpkeepalive 0 but I don't think it's going to solve my issue. I just want the MacBook to stay asleep as long as the lid is closed.

Turns out I didn't set "Run this task when the system next wakes" in the CCC schedule configuration (unique to each task, not global via preferences). Had it set to "Wake the system" before, so with this change I expect the MacBook will stay asleep.

I've noticed my macbook is logging several "DarkWake from Standby [CDN] due to ARPT/Network: Using BATT" activities. I'm also getting several logs of "driver is slow".

Does anyone have any ideas?

After another 8 hours, from 75% -> 43%. Huge Battery drain.

Tonight I will disable BT.

Same on my end.

Battery of new Mac Book Air 2018 is draining 5-10% overnight.

Observed right from beginning.

Logging Timestamps since Dec 17th now. Absolutely no improvement on draining issues. Every night 5-10% battery drain.

Apple Support contacted and they told me to go to Genius Bar - but in Munich I am not able to get any free slot at Apple since weeks. That is really a annoying support for a 1.500 €/$ device ...

I've got the same problem.

Since I clean updated from Yosemite to Mojave, battery loses about 5% during night. This doesn't happen always, at times there is no battery drain at all. Other times I lost about 20% in an hour of sleep. Deactivating WIFI and bluetooth doesn't solve the problem.

Also the media keys (play/pause, next, previous) don't work anymore since the update if I'm playing music via bluetooth. Furthermore, the iTunes player in the sidebar doesn't function properly any longer.

I feel like Apple isn't testing its software updates thoroughly enough before releasing them.

It doesn't look like they invest much time into taking care that everything works on older models, too (MacBook 13" mid 2014 in my case).

No one at Apple will admit to this problem. I just upgraded my 2017 MacBook air to Mojave and battery drain makes it impossible to use it for more than four hours. Same with a brand new MacBook. Some people will try to blame Chrome and other software but even using just Firefox browser and eliminating Chrome related stuff, Mojave drains the battery. As usual Apple will keep mum and eventually provide a solution I guess. Don't expect a straight answer. Apple is perfect so it must be fault of other programs or our fault!

This discussion is about battery drain during sleep. If I could use my machine for 4 hours, I would not complain. Sometime I can only get an hour out of it. It all depends what you are doing.

If you go to Activity monitor one of the tabs will tell you which apps are using energy. On this web site Safari uses 1% energy but on other with all the adverts flashing and rolling it uses a huge amount of power.

What would I know! I am just a guy with ten plus apple products. I decided not to upgrade to the fancy new system on two of my MacBook Air that are older. The new one cannot be used at work so I use it at home.
