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.
Something new? Has anyone installed the MacOS Catalina beta? Maybe Catalina solutions this error, if this does not solve it, I will sell my Macbook 12inch and look for a touch screen notebook to install GNU / Linux.
I bought the MacBook because I thought that I will have no problems with the system, and each update will run smooth and without problems for a long time. Sadly I learn it's not the case anymore, which is unfortunate.
I am still with my HS on mine, and I might stick to it until it works because it works perfectly. Still disappointed that I can not enjoy at the same level the lates macOS.
I am so curious if Catalina 3rd or 4th update will manage to fix the problem (as far as I understood, from the 3rd version the macOS's latest updates are better optimised)
Thanks guys for keeping this thread alive and up to date!
These issue not happened my MacBook Air 13 inch 2015 (Mojave 10.14.5), but one of my friend saying this issue occurred in his MacBook.
I don't know whether I missed any software patches for battery life.
Actually there are 2 issues here.
I believe - correct me if i am wrong - our major issue the past months is the second.
And since i have a MacBook Air 2015 like yours i have to ask:
Are you referring to the first issue? Me i never had such problem.
If you are referring to the second issue, do you have actual memories (or even better saved stats or something) of your Air on High Sierra? Are you sure that it can hold up the same hours while in Mojave?
Same issue on my MacBook Pro 2015. Apple hasn't been super helpful in this situation. I went to the Apple Store and they essentially blamed my 'non authentic' hard drive as the issue (makes no sense as the drive is an actual Apple drive).
We shouldn't have to be messing with pmset values in terminal to fix Apple's battery issues in Mojave.
Such a shame when Mojave is clearly the issue here. Never had any issues with my laptop draining 20% over 7 hours in clamshell on older OSes...
@pixelalb, how did you reach to this conclusion? I think there were people posting here which had new Macs (2018) and older Macs and had the battery drain issue while in sleep mode.
While in use, both of your Macs work fine? no major battery drain on either of the models?
Thanks!
Thanks for your feedback! I am using a MBA 2017. So by your understanding I should be able to upgrade to Mojave and later Catalina without being worry that I might experience any battery drain during sleep mode?
Still it feels like a gable game. It's like back in the days when we "upgraded" our PCs to Windows Vista and were not sure what we will get besides the new cool look :)
Anyway, at this point I'll just wait for Catalina to be out officially and see after
Agree with you 100%. I went through over a month of tech support and tried 4 different brand new Macbooks with no resolution. I bought 4 brand new products and suffered like I was trying to save an old broken down 1995 computer. Unacceptable.
I am convinced that Apple is "cheapening down" as this 2018 Macbook is an inferior cousin to its 2014 predecessor. Even the charging cable is crap. I will be shocked if this Macbook lasts me 5 years (the average life of my previous Macbooks).
Hi guys,
Just purchased a brand new 2019 MacBook Pro (i7 9xxxx series) and yep... the battery management is aweful. I can't work more than 2 or 3 hours straight on it. While in sleep mode, it looses 15 % of battery...
My last Mac computer was an ibook of 2004, last me 6 years without any issues and managed to lose the same amount of battery power after a MONTH of sleep. What a disapointment to spend more than 2000 euros on a high end Apple product and having to suffer this kind of issue.
I'm just glad I'm not the only one and that all of this will be addressed very shortly by Apple with a software fix...
My brand new MBA 2019 with 10.14.5 is suddenly having invisible power use. I use top -o cpu and don't see any process using up CPU. Sometimes WindowServer shows up but usual it's just top itself using a few percent of one CPU. So no processes using up power, but yet, my powerpack (external battery) puts out 15W and I'm not able to charge the battery. Sleep mode (lid down) sometimes helps, sometimes does not. When I run Intel Power Gadget I see a CPU temperature from 50C to 60C That will drop to 40C after a while with the lid down, but that still seems a little warm.
Up until this morning I had no power problems. I did nothing special this morning. I have updates turned off. It would take forever to download the 3 GB of updates here at home so I can't do that right now.
What do you guys know about the new macOS Catalina, is the beta version ok? I saw only one post here and sadly it seems that the problem stays with the new update as well. What do you guys think/heard? Or is too soon to tell? Thanks!
I think this is my last apple laptop. After so many problems with the battery that prevented me from reaching the end of the day at work, I decided to install a Linux distro on it and I can assure you that everything is a software error. With Linux I have 11 hours of autonomy in my laptop again. I'm sorry for apple but we've been with this unsolved error for a year and it's going to be the last macbook I bought. In the meantime I will work with Linux to at least take advantage of the hardware.
Greetings to all.
What I tried so far:
sudo pmset -a standby 1
sudo pmset -b tcpkeepalive 0
sudo pmset -a hibernatemode 25
sudo pmset -a standbydelaylow 60
sudo pmset -a standbydelayhigh 60
I also discovered that Reminders wake up the Mac:
2019-11-14 07:45:04 +0100 IORegisterForSystemPower: ...HasPoweredOn...
Wake Reason = RTC
wakeType = Alarm
2019-11-14 07:45:04 +0100 IOPSNotificationCreateRunLoopSource
so I turned notification of Reminders completely off.
i am having the exact same issue, i've been holding off on updating my macbook because i have been busy working on it and decided to finally update last night. i've been using it in class all day today and my computer keeps turning off around 40-48 percent. i have never had this problem with my mac before until today. what can i do to stop this from happening i can not keep having my computer turn off on me while i do my work.
I'm having the same issue here! Battery will drain while the computer sleeps. It drains about 5% for every hour. Also the battery meter (menu bar) is wild. Started at 41% when I read this post, was at 33% when I started typing this reply, now is at 36%. I have a Macbook 12" Retina Early-2016, did a software update from High Sierra. Please someone help! PS: I already did some coding via Terminal to kill the Wi-Fi signal used for Find My Mac, but it didn't help.
