macOS Mojave battery drain

The instructions you sent may resolve the power management issues, but what about the rapid draining of the systems when in use? My 2015 MacBook Pro drains to 13% within three hours; I never tested it but it usually lasts throughout the day. It is also noticeably warmer. Is there a procedure to revert to the previous version?

Do you have solutions with problem macbook air 2017 like me? My battery have a bad condition: replace now. Because im upgrade to MacOs mojave. And im new use my macbook 3 months. That hurt me. I feel bad for upgrade mojave. Help me

Since updating to MacOS Mojave on my Macbook Air, I am too having a battery consumption issue.

When closing the lid, I am losing about 20% battery capacity overnight (8 hours).

This was not an issue for me before the Mojave update.

Apple, please fix. Thanks.

I too am having an issues with massive battery drain on my 2015 Macbook Pro (15" i7). Battery cycles are under 200 and on High Sierra I could usually get 5-6hrs with moderate workload. Now my battery drains within 1-2 hours using only email and web browsing. On top of this the Macbook Pro is running extremely hot and the fans are running almost consistently at full speed.

Borderline unusable in this condition unless I dock the machine and only use it as a desktop.

Same here. Battery life is terrible now. I can barely get two hours out of it and it shuts off when it gets to 35%. Start up is wonky, too. Two thirds of the way through the progress bar of start-up the screen goes black and I get the dreaded beachball for about 20 seconds before the desktop launches. Then, it reverts my desktop image to an older one. Weird. NONE of these problems occurred before the Mojave install.

I tried resetting PRAM and the SCM, both. Neither process fixed the issue.

Me too. 2015 13" MBP, Charged 100% last night. This morning I opened the lid to find I only have 60% battery after 8 hours. Never happened before. Similarly, I have wifi issues connecting (or not) to different networks after upgrading - but I'l post that comment in the wifi discussions.

Apple - we need a patch for wifi and battery drain please.

I have the same exact issue. I have a MacBook Pro 2016 13 inch with Touch Bar. Computer was completely charged last night. When I opened it about 10 minutes ago, the battery had drained down to 55%. This needs to be fixed ASAP!

I too have the same problem with my 13 inch macbook pro retina early 2015 edition. Battery drains multiple times faster than that was with High Sierra. My battery is healthy still only 130 cycles old.

Hi,

I have exactly the same issue with my Macbook 12".

I charged it full yesterday evening but this morning i had approx. 45% left of battery time!

This issue has never happen before upgrading to Mojave!!!

Please help with this issue!!!

2015 MacBook air same issue...

I was on Sierra 10.12.6 before updating and I would get a few days of light usage!

Battery is halved now, or even less. Drains heaps during sleep each night, I've even turned wifi off some nights.

Same issue here, MacBook Pro 13`, 2016. It drives me crazy, 30% gone after 1.5 hours of usage. Started right after migrating to Mojave. Still an issue after one week of using it (so its not background indexing).

Same here, just updated from El Capitan (Macbook air mid 2014) , and the battery percentage is getting down so fast compared to El Capitan, please, fix this, thanks god i did clone the whole disk (bit to bit).

Wow this seems to be a genuine and huge bug in Mojave. I ran the update last night and today closed my MacBook for 3 hours only to find I’d lost 30% in that time. I’ve had to switch computers to get my work done now 😡. Under high Sierra this wouldn’t have happened.

Same here... reset both.

I was on Sierra before and my Air would last a few days with light use. Now I'll only get a few hours and have to charge it each day.

Very frustrating as Apple should finish testing everything before releases

Apple DOES NOT monitor these forums.

Apple hasn't said *anything* about any bugs in Mojave that they haven't already fixed. This is standard procedure for Apple unless it's a really bad thing that they issue a press release about.

The only way to get Apple's support on anything is to file a Radar (Apple's in-house bug tracking system) and I haven't done that in years so I don't know how one would do it when you're not a developer. In any case, what usually happens is that if it doesn't get marked as a duplicate you can assume it will be ignored because nobody else has complained, or if it IS marked as a duplicate they obviously know about it so you have a slightly-better chance of getting it fixed.

Generally, a problem like this is some driver somewhere that's leaving something turned on when they shouldn't (which will eventually be found and stomped) or some new behavior (like indexing a filesystem, or your pictures, or something like that, which happens when you reinstall the OS) which is expected behavior and will just suck power for a while until the job is done.

In any case, my guess is that it will get better over the next few releases as they find bugs and stomp them.

THIS IS WHY YOU NEVER INSTALL THE NEW OS UNTIL IT HAS BEEN AROUND A WHILE. Let someone ELSE do the testing for Apple.
