macOS Mojave battery drain

can't you create a bootable USB with "install macOS High Sierra" file, boot from the flash drive and install HS? Don't tell me they don't permit HS installation on the latest macs???!!

Thank you! Waiting for others to test out the same thing to see if its just me.

Update on disabled content cache: 18hours since last charge and battery was 99% when i opened lid just now.

laptop ( battery) is 5 years old.

Y'all can check your battery status: (OPTION KEY + APPLE IN THE CORNER TOP -> SystemInformation (first option) -> battery (third option) ) check your mAh and post it?, look my cycles only 87 and i cant believe that i have about 2 hours of battery life, more than $2000usd in my loved one third world country for this???

Anybody has try the preview of 10.14.4?

BTW: i just test the next one, its so annoying but when i use the keyboard my battery life decrease, i dont know why, i read that the new mbp keyboard and the battery are together but it doesnt have any sense that improve when i click nothing but read a web for example.

I have tried everything: SMC reset, PRAM reset, clean install of Mojave, clean install of High Sierra... my MacBook Pro 15-inch 2018 won't actually "sleep" when I close the lid. It goes to sleep (and doesn't loose battery power) when I actually click "sleep" (or "shutdown") before closing the lid. This is odd and annoying.

Final update.....

New MBPro with Mojave native just as bad as new with HS and Mojave upgrade. Battery drain is so significant that AppleCare has concluded that I have tried and done everything possible. Therefore, I am returning today for a full refund. This 'tacit' understanding by Apple (Senior level) without even doing any diagnostics, confirms that Apple knows that there is no fix at this time. I will revert to my 2013 MacBook Air and suffer for a while with the slower processing of my photo editing software. When this is fixed, whether through software or new hardware; I'll return for another laptop.

For those of you who have purchased a new MacBookPro; there is no solution to this problem at this time. As much as I like the speed and performance with my applications; I refuse to accept this faulty equipment--even in running only HS. Therefore, if there is any possibility that you can return and get a refund; then do it asap. Otherwise, you will ultimately be part of a class action claim and resolution that will not return close to what you have spent; in time and money.

I am disappointed with Apple, but not abandoning them. I trust that a solution will be forthcoming.

Just do a backup of all files you may need and restore your mac to default OS. Than install high sierra (google install file) and stick with that ! everythin might take a while to complete but once you have done that youre all set BTW !!! IMPORTANT !!! do not install any new OS UPDATES I did that while ago and dont have a problem anymore (just keep a copy of your old OS on seperate drive and in case if you may need some of files just copy them over - at same time you wil free up alot of space on your drive)

I've read the entire thread and from my take from these 2 replies...

(@pduke 7 on 4/29/19 As far as i could understand the battery drain while sleep was fixed and we were left with a major general battery drain while using mojave. AND @ED in PA on 4/29/19 I believe you're right. The wake drain problem has never been solved by the thousands of people who visited this thread after Mojave hobbled their healthy batteries.)

the batteries were damaged/drained from a Mojave issue but the fix could NOT reverse the damage already inflicted. Therefore if you have a newer MBA , your battery was probably damaged but not to the extent that you cannot use your computer without it being plugged in so you wouldn't notice anything wrong. My MBA, which was about 3 years old at the time of the Mojave update and my mother's 2 year-old MBA were inflicted with enough damage to the battery that it now needs replacing.

Apple will not admit this. I've taken my computer into the store twice and have spoken over the phone with tech support hoping to get the battery replaced at a discounted cost considering the issue (going over both computer and their battery issues occurring within the same time frame). No luck!

@ Yunrazzy

A promising lead, but to no avail in my case. There is no process called "qemu system x86_64 mac" in my library or system. The CPU is not being overloaded by anything in particular, but still the battery drain (awake drain) issue persists on my MacBook Pro, and has continued since the day I installed Mojave.

Qemu has caused problems for users of Mac OS. It does hog almost 100% of the CPU for some people. For the curious, search the Apple discussions site for the term "qemu," but, a warning about searching for "qemu system x86_64 mac" on Google. It turns up very sketchy looking sites that may do more harm than good. QEMU (abbreviation for Quick Emulator) is an open source virtual machine hardware emulation hypervisor that performs hardware virtualization; that is, a Linux emulator used to create virtual machines. QEMU virtual machines emulate all devices needed to run a VM Guest.

I don't know how it ends up in unsuspecting users' systems but I'm glad it's not in mine.

Your MacOS has may have over heated or charged for to long, this can cause your battery to burn out or you charger to breake,

I recommend getting a new charger if that doesn't work change battery to a new one.

For a fact I know going back to Sierra solves all problems (and not the High Sierra)

Try disabling your Bluetooth this time I hope you could get back at me if you had any improvement (overnight time wise)

Yes, clean install of High Sierra. That solved my problems. :)

I didint have that app citrix that someone else up here pointed out but what I did is I went back to macOS Sierra – version 10.12, and that fixed my issue on one of computers and the other one is simply brand new and i dont have a time machine point I could use to go back!!! whats worst is my wireless devices completly stopped working now I need to have my mouse and track pad bplugged in at all times !! GO APPLE

Dear Apple community users,

FWIW, I am not a professional user of a MBP with Mojave 10.14.3 but I have the following experience (sorry for the log list J):

·      When I bought my Macbook Pro early 2015, it came with El Capitan installed.

·      I upgraded to Sierra without any performance problem.

·      When I upgraded to High Sierra I got a better performance but the battery drained 25% faster.

·      Upgrading to Mojave did not improve the battery drain.

·      I am only using Mail, Safari, and occasionally Word and Powerpoint.

·      I am not using iCloud, Bluetooth or any other extension to the system.

·      My storage usage is only 30GB from the 250GB available.

·      My battery cycle count is only 155.

·      None of all the suggestions for improvement that were made on this forum or others resulted in any improvement.

·      The only thing that changed with High Sierra is the file system that is now APFS !!

Can somebody of you, experienced user, who may have a good contact with the Apple development, get confirmation that this may be the reason for the higher battery drain ?

Or check that users with the old file system do not have the same bad experience ?

Should this be the case we can all stop nagging about it and only hope for an Apple fix in the future.

Or revert to Sierra, as was already suggested, and lose some of the nice new features in the new releases. 

Have been following this thread for sometime now and most people seem to feel it's a problem with Mojave and not the new ADFS hard drive format.

Are we all agreed ?

If so how does one go about a fool proof backwards update to High Sierra ?

If this would solve everyone's problems surely this is the way to move forward (by moving backwards ;-0 )

Then we can boycott Mojave until Apple sorts itself out.

I find it hard to understand why Apple has not chipped in and added something to this discussion.

Sadly I feel Apple have lost the plot and from being the world's leading computer innovator have slipped into producing expensive electronic jewellery.
