macOS Mojave battery drain

Same here. 2013 MBP Retina 13". Updated to Mojave yesterday and was fully charged when I closed the machine and took it home. Opened it this morning and the battery was completely drained.

Not sure why this is happening to some people.

I never shut my MBP down, always leaving it sleeping overnight and I have not experienced this.

The only possible explanation I can think of is if the mac for some reason failed to enter sleep mode.

The font will appear blurry on any pre-retina mac. Apple removed what they used to use for making the fonts look sharper. On retina displays it’s not as noticeable, if at all from normal viewing distance, but it doesn’t look so great on the lower res displays.

Hi From Belgium,

same for me , I upgraded a MAcbook12 2015 ,and battery drain very fast. After 10Hours in sleeping mode, battery totally empty!! Grrrrrrr Of course PRAM , etc... change nothing....

No software running, nothing.... it seems that the computer don't go in sleep mode....

GREAT APPLE! 100 000 ingenieurs to have this king of bug!! 'Chapeau'

I do not know how to downgrade to High Sierra, but I will tell how I did it.

I erased the whole SSD by accident. And I reboot my MacBook Pro 2018, found a global sign spinning there. I connected my Mac to wifi and it automatically download High Sierra for me, which was my open-box system. My hypothesis was that there may be some auto-recovery method out there in Apple's system which assists us to find out the original system installed in the macbook we use.

Anyway, that was how I got my High Sierra back, typing with High Sierra right now.

I updated MacBook Air to MacOS Mojave when it became available. In several days, my battery started die in 4-5 hours. Then, notification about battery health appeared(computer is pretty old so it is logical).

Now, it is alive only for 3 hours. Before new macOS, it was alive for at least 8 hours. Maximum capacity of the battery decreases rapidly. 2 days ago it was 4800 mAh, whereas now It is 4300 mAh.

Don’t want to become that Windows guy with charging cable tail...

I have the same problem too.. I have MacBook Pro 2017, just update to MOJAVE 3 days ago.. now my battery life only last 4 hour on my daily use, its so depressing i usually get 8 hour more..

I think I am going back to high sierra until apple release another os update with no one complain about this anymore..

cheers

For some people here resetting PRAM and SVC helps, but for me it did not, I am seriously considering my future when it comes to apple products, its unforgivable stab in the back. Huge productivity hit from a company that heralded productivity.

Apple are not monitoring this forum. I suggest everyone here to take the case to Twitter, mentioning @AppleSupport, at least they respond there. In short, they don't admit that there is any problem with Mojave and they say that its probably third party apps, which is a total ******** so it seems, judging by the comments in this forum.

I have the same issue. I haven't upgraded my MacBook Pro 2014 since Mavericks because I noticed that my Mac started to become sluggish and the battery drained a lot after going on Sierra. I have gone back to Mavericks after that since I get 8 hours usage out of my battery and everything is snappy on Mavericks. I have, however, decided to go on Mojave since I really like the new design and there are heaps of bug fixes and extra features compared to Mavericks. I must say that I was first pleasantly surprised that my MacBook is still extremely quick and snappy. I love the Dark Mode and there are heaps of new features that I love and haven't had on Mavericks. However, the battery life is terrible. The battery sometimes drains 25% overnight if I leave it on sleep mode. I didn't lose 1% with Mavericks for a whole week. I have noticed that that the battery drainage isn't too bad and lose about 1% overnight if I close all my applications. It's not a real solution since I like to have my programs open after waking up my Mac. Apple really has to sort this out and release an update. With normal usage I get half of my battery time compared to Mavericks. Around 4 hours. That's not good enough. I don't want to downgrade to Mavericks again since I really like Mojave, but the battery life is really a problem.

All these are background services which are meant to be terminated automatically when the lid is closed. but in Mojave it's not happening., these services prevents the system from sleep and it drains the battery. Apple needs to fix this but they are not ready to hear us.

Well, I am completely baffled now. Thought the pmset -g would sort it out as I was putting to sleep only when there was nothing showing next to the sleep column, BUT, I am still loosing way too much battery on sleep. 8% in 4hours this morning and my pmset -g is showing the following;

I am no longer going to use sleep and will be turning my MacBook off whenever I am not using it

Hi all,

I installed 10.14.1 developer beta yesterday, for me it looks a bit better there.

I have a mid 2015 pro and updated it last week from High Sierra. Went from 62% to 27 within a hour and a half. I was told by an advisor that the only way to revert it back to high Sierra is if you happen to back it up when it had that OS.

I had similar experience with a couple of the fixes that people have said worked for them. The drain seems inconsistent, I have seen drain over 10 hours range for 5-10% to as much as 50%. I have just installed the 10.14.1 update and performed an SMC reset. Lets see what happens overnight.

Mhm... thats really strange. https://www.imore.com/how-fix-missing-serial-number-macos this seems to be a way to fix this issue, but it sounds dangerous, I would prefer to take your device to apple or an apple service provider.
