macOS Mojave battery drain

Well I thought my issue was fixed after 10.14.1, but now it appears that it is not. After working on my MacBook for a bit this morning, I put it to sleep mode. Three hours later I opened it and the battery drained by 10%. This is very frustrating.

Update: battery still drains overnight, but just a few percent. Looks like there are several things that have been triggered by Mojave - so, probably, no single solution. It's now manageable for me, though I'd like to return to just a couple percent overnight.

Just updating anyone interested... this worked for me and my battery is not losing any charge when in sleep mode:

- disabled TCP in sleep mode with this command: sudo pmset -b tcpkeepalive 0.

- changed the hibernation mode with this command: sudo pmset -a hibernatemode 25 (the default is 3).

- disabled unlocking of my MacBook Pro with my iWatch (I read somewhere that was causing issues.).

- disabled transparency in Accessibility.

- turned off Dynamic Desktop.

My battery is back to normal (maybe even better) operation.

Same here MacBook Pro not using dark mode but on Mojave and battery life drain is ridiculous even when hibernating is this another case of Apple forcing everyone to replace there MacBooks like they do with the iPhone battery scandal

Over the last weeks I have tried several things to get rid of the sleep battery drain. Sometimes I thought it was fixed and then I would have another night where there was big drain.

Latest thing I tried is changing the hibernate mode setting to 25. Yes, it means there is a little lag in opening up the lid and getting going but overnight drain seems to be under control (I say seems to be - I need to give a few more days to see what happens). Tentatively optimistic, but I am disappointed in Apple and their response to this. I have never had an issue upgrading before but this time seems to have brought several problems.

Hi all,

please contact Apple support like I did. They need more information about this issue. As far as I know, apple is not monitoring this boards. As the name says, it’s an user community! I contacted apple support via twitter and after some chat session I got called from a really good senior advisor. So please please get in touch with Apple Support to let them know there is a real issue!

Best,

Ole

Hi berk136. Very interesting. I would be interested in learning more about this from your source. Could you link to where you found out about this as a 2012 issue?

To others, if anyone else has tried this and can verify that it works, please let me know.

Hi berk136, thank you. I found this file only in one user (I have 4 users in my MBP). Not sure why this file created in the first place. Very interesting.

Correction, the file name is com.apple.desktop.plist instead.

Yes, of course!
Here is the link:

You can see how people went crazy on the comments at that time. For some it improves 2-3 hours, for some it doubles the battery life, depending on the model I guess.

I can not find this file.

I have already done all the "solutions" presented and continued without being able to solve the problem.

Sometimes it seems that everything is solved, however one day the problem comes back.

This is the correct file name, i hope it works for you as well

You are still missing a letter "t": it is

com.apple.desktop.plist

Just to clarify, having this file is perfectly normal; everybody should have it.

However, it is possible that for at least some of the people affected, this file is somehow corrupted and therefore is causing the problem.

I would be interested to hear whether or not deleting this helps people.

Sorry for the double trouble, I was writing in haste while I was working meanwhile.

So as I understand, this file might be corrupted and that’s why some users have battery drain problems, while others have improved battery life?

Also just curious, when I deleted the file, did osx automatically replaced the file? Or how come osx still works without this file?

Sorry if I ask too much, again I’m just interested to learn about it

Mine MBP was also facing this issue after Mojave update. I was waiting since 15 days or so hoping this issue will be fixed automatically. But today I did following things and now it seems issue is resolved:

1. clean reinstallation of mojave

2. added Sd card to privacy to avoid indexing of it by spotlight. Also unchecked Film, Movie and Image option from spotlight indexing

3. Uses the following two commands as suggested in the link https://www.youtube.com/watch?v=ghtjOat0tKQ

The Commands for Terminal are

sudo pmset -b tcpkeepalive 0

sudo pmset hibernatemode 25

Now my MBP battery back is back to normal -around 9-10 hours.

I am using MBP 13" retina early 2015.

Oh well, thought that this would solve my battery draining problem (losing through sleep seems to have levelled out) but turns out I don't even have com.apple.desktop.plist to even delete in the first place 😟
