Just updated my OS to Mojave this morning and brought my laptop to work. It was on full charge when I left home. 2hrs after using it, the battery percentage was down to 40% which never happened before during any of my regular use. Also, the texts on the screen are blurry.
MACBOOK AIR (13-INCH, 2017), macOS Mojave (10.14)
Ok, so i solved this problem on my MacBook Pro 13'' (Early 2015). It turned out that battery drain was caused by fully loaded CPU (almost 100%). So, you can check this out, just open Activity Monitor (Finder - Apps - Utilities) and then look up for CPU tab. And then just watch which apps and processes uses your CPU. You can also check out other tabs and overall system and CPU load.
So it turned out that my CPU was used by the process called "qemu system x86_64 mac" and this was the reason my MacBook Pro had zero battery after about 3 hours after full charge. If you have the same process, just google the name of it and then you'll find the link to the thread on Apple Community on how to delete it (it's not that simple tho).
It really worked for me so my macbook works fine right now.
i don't know if they will turn to banking or just become titanium card manufacturers..., but for the sake of Steve's 90-92 designed OSX masterpiece, the strong bonds with the millions of professionals that stood for them( and they stood back, "apple computers") for decades and the rest of "todays crowd" that can still tell the difference between style and pose, they have to do better.
I mean we are with Cook on the wheel, he was the "chosen", imagine what will happen when the next one turns up!!!
More than half the people i know use macs and iphone cause of fashion, they can't even understand what design(software and product) is. Are we left in such hands?
Folks,
An update, FWIW.
My new MacBook drained battery (when unplugged with lid closed) overnight maybe 1st and 3rd nights after first connecting to internet a few weeks ago. It has not drained since when left overnight without power.
Some of you report changes to battery rate-of-draining but I have not tested that; I'm rarely unplugged for more than an hour or two when working. If this becomes an issue, I will try some of the workarounds posted here (thank you).
In the meantime, I'll guess these were critical updates (Apple) or critical malware (China) that are triggered to install themselves on new systems and that Apple is too busy (or worse, cannot easily reproduce) to make transparent. Even if this is false, it makes for a great movie plot.
Also, has anyone checked the logs? I have not used Console app much but would think that any background updates would log something meaningful?
2c,

Hi Dan! Thanks. I don't know why but I believe that MBA and especially the 2017 version are not impacted by the battery drain issue. But checking the recent messages posted, I think I will hold back for a while more before taking the leap :-)
It's been too long since I updated to Mojave so I can't go back to HS or some things won't work properly (at least that's what Apple told me). I'm running 10.14.4 and I'm still having issues.
On another note ....my son just got a new MBP 2018 this past week and he said the battery doesn't last as long as his Late 2012 MBP which is running HS.
YES me too! I JUST got this new Macbook last week and I've spent the past 3 days with Apple Support trying everything under the sun. Nothing worked so I googled and found this thread. Clearly, it is a KNOWN ISSUE. This brand new laptop has the same battery power as my 5 year old Macbook.
Never had this issue before. Every 5 years my Macbook would die and I'd get a new one, seamless transition, no
issues. But now it's draining at 1/3 of the advertised rate of 10 hour battery life. And no one seems to know why.
Does anybody have a 2018 Macbook Air that doesn't have a bad battery? I've had to buy and return two so far and each one (brand new) had this issue. I'm about to try a 3rd one but I'm losing hope. Apparently Sierra OS does the trick but on the newest Macbooks you cannot downgrade from Mojave. Has anybody bought a 2018 version without the battery issue?
Spent over $4000 for my MacBook Pro to replace my 2015. Shipped with Mojave, last one had High Sierra. Battery drains 40%+ over night. Previous computer that had more background processes would lose less than 5%. This is ridiculous, Apple. Even Hibernate Mode 25 isn't helping. You need to patch Mojave, because that kind of drain will ruin my battery and turn my computer into an extremely expensive paper weight.
Any news on whether this has been solved? If this has beens solved by Apple? I have bought recently Macbook Pro 2019 13 inch - base model under Mojave. I'm monitoring my pro's battery life - it takes like only almost 6 hours of use - not the 10 hours as advertised. I'm only doing light web browsing, watching youtube at 40% brightness of monitor and totally turned off keyboard backlight.
I hope more and more people report this but I've seen like 4,000 Apple Forum comments and Apple uniformly denies anything is wrong. I would think 4 new products in a row with the exact same issue would indicate a serious issue...but they won't do anything about it.
wow! this is crazy. supposedly macbook air has the longer battery life than pro. I have the pro 13 inch 2019 and it only lasts 6 hours of normal use - which is crazy! Previously I had macbook air 2015 - it lasts for a day unless of course I'm playing civ 5.
I'm not sure how to report. I have never encountered this before with my macbook air. I just had a brand new pro and the battery is a disappointment! I had left it on standby from full charge of 100% when I came back - after 12 hours -it's now at 60!
Apple is recalling the batteries on old Macbook Pros -- when are they going to recall the defective 2018 Macbook Air batteries???
CUPERTINO (CBS SF / CNN) — Apple is doing a voluntary recall for
certain versions of its 15-inch MacBook Pro laptops due to batteries
that “may overheat and pose a safety risk.”
In a notice issued Thursday, the Cupertino-based tech giant
said the units were mostly sold between September 2015 and February
2017.

My 2018 Macbook Air battery also heats up dangerously hot just when I'm browing the internet. I know this battery (and the 3 batteries in the 3 previous new Macbooks I tried) all have the same issue.
They need to issue new Macbooks to people, not make them send them in and get new batteries and go without a computer for like a month. This is so wrong and frustrating.
Hey guys! I am still on HS on my MBA 2017.
Reading your comments I can see that for some of you the battery drain was related to certain apps that after update were not fully, lets say, optimised for Mojave.
Can it be that with only pre-installed apps one should not experience any battery drain?
Some of you said that the brand new MACs had the battery drain issue. Did you guys installed some new apps that might cause the problem right after getting the computers?
I do not plan to install apps on my MBA as I am only using it for internet browsing, nothing more.
Thanks!
Unfortunately apps was never the case for me. I have installed mojave 4 or 5 times on my MBA 2015. I tried both upgrading and clean installs. Autonomy was significantly pour all of the times. I stopped trying after 14.4. MBA is castrated without its "ridiculous" battery life and i am bored of trying. I am on HS and as far as i can see, apple won't be fixing this until Catalina(or may be not??). We are 4000 in this post and since apple is ignoring us... are there any you tubers among us...? we may be needing to start shouting about it!
I spent 20 hours troubleshooting with Apple Tech and 10 hours driving to get it looked at in the Genius Bar. So I exhausted every possible thing and no one found any reason for it. Nothing I had or did was anything my 2014 Macbook didn't handle without a problem.
