macOS Mojave battery drain

I have done the same. now its fine. I think its time to wait for new update that apple fix this batter Drain problem. I don't think it will be wise again to go back Mojave as that drain much battery in sleep mode.. though I love the dark mode and stack very much.

I have the same issue. 2016 MacBook Pro 13", since updating to Mojave significant battery drain overnight. This happened when doing the update path and also with a fresh install.

Apple - whats the fix?

Thanks so much 'unilrn'. You are a genius after exhausting all other options and none working, you the hero came along and resolved my battery drain issue. Thanks so much for sharing and I hope you have a great day. 🙂

Hi JRC,

That's a good idea. I did that and it gave me the following response:

"sleep prevented by backupd, sharingd"

I removed the automatic time machine back up. But, what is sharingd? Does that mean that I have to disable AirDrop, Hand-off and anything related to sharing?

Same here, turning updates of didn't help.

Default settings overnight I lost 10% in just over 10 hours. Then turned updates off and left my MacBook through the day. In the next 10 hours I lost 40%. It may work for some but its certainly not a fix for all it would seem.

My 2015 mac was *perfectly* fine before this update. Now, I can't use my computer for more than 45 minutes-1 hour without worrying about battery life. Lagging is insane, battery life is almost non-existent, and there is very loud computer fan noise all the time now. Just typing this message in 2-3 minutes my battery life has drained from 10%-7%! I want this fixed promptly. I can not get through a school year with these persistent issues.

same here, battery drain is crazy and laptop is getting really hot like I am doing processor intensive stuff and all I am doing is email, also charging very slowly and battery percentage on the menu bar is all over the place, keeps changing up and down, its on charge and my battery level is STILL going down

I previously tried the tcpkeepalive 0 setting - seemed to be working at first but still lost 30% overnight. Hoping 14.1 will fix...

But, just updated my MBP to Mojave 14.1 (in the hope that it will fix the battery drain issue) and noticed that "About This Mac" no longer shows the version or Serial Number. I can get the S/N off the original invoice (luckily, I keep emailed invoices from 2014) or my iPhone - but it suggests something amiss.

I don't know if the loss followed the original update or just the latest. Anyone else notice this?

After 10.14.1 update, I left my MacBook Air to sleep at 11:00pm @ 100%, woke up at 9:00 am, the battery still has 97%. 3% drops during sleep seems more acceptable to me. Now need to observe the percentage drop during usage.

Didnt fix it for me. Came to find my 2016 touch-bar warm this morning. Battery down from 100% to 72% overnight after updating to 10.14.1. And had the random hang as well where nothing responds for a minute or two.

Having the same issue here. I have a MacBook Pro 13" retina, early 2015, with 500 or so battery cycles (so a normal battery) and battery life is not good after upgrading to Mojave. I also tried doing a factory reset, didn't help. A patch is needed urgently.

Solved my problem perfectly, changed the settings and my 2016 MacBook 12 inch had no power consumption during sleep. Went to bed at 100% at 10:00 pm, woke up at 7:00 am and still 100%.

Good Man @dinecko

Upgraded to 10.14.1 ent from 100% at 8pm and the next day at 4 pm it was down to 21%. I started to also notice the battery would actually from up and down. I saw it at 23 then 22 then 20 then 21 then 22 then 20.

I re-ran the tcpkeepalive command again to see. I dont show any processes causing sleep to fail. smh

It really seems fixed for me now.

Pretty sure I disabled it a few years ago, i'll double check when I get some.

But to recap so far:

SMC Reset didn't fix.

Reinstalling using the CMD R didn't fix.

Updating to 10.4.1 didn't fix.

I reset the Pram before I left for work today, will see if that did it.
