macOS Mojave battery drain

had the same problem. then I downgrade to high Sierra. now everything perfect. waiting for new update. may be that update fix this drastic battery drain. until that I am on high Sierra.

Just wondering: do you have Power Nap turned on while on battery power?

Try turning off automatic updates. Worked for me. It’s enabled by default.

I disabled automatic updates ( a new feature) which sorted it for me.

Hi there!

Battery drain is common for time periods up to a few days after installing an update. This is because the system is still optimizing itself after updating.

Hope this helps!

Post the report in your reply so we can examine the reporter for suspicious 3rd party software that could be contributing to the problem.

Disabling content caching fixed it for me. Standby barely touches the batt.

Who else has tried that?

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???!!

Same problem. Battery drastically drains after the update, in particular while the Mac is closed/sleeping.
For the moment, I'll downgrade to High Sierra and wait for further patches, hoping to get back original juice performances... I was really enjoying the new features and the overall behaviour of Mojave in my machine.

Thanks a lot for your findings and hints. I don't know why "standbydelayhigh" was set to the equivalent of 24 hrs on my Macbook after the update. It's no wonder that the battery drains super-fast with this configuration. After doing the needful (set to 60 Seconds), my MB12 appears to conserve way more battery then after the Mojave update - likely to be back to normal. Will keep an eye on over next days...

Indeed, the Activity Monitor isn't of any help here. It's useless!

What's your Terminal > pmset -g > standbydelayhigh current value?

Hey Steve,

could you attach a screenshot? My MBP shows the right stuff at "About This Mac". Please have a look if your S/N is shown in "About This Mac" -> System Report -> Hardware. Did you already try a reboot?

best,

S/N issue fixed quickly by Genius. It was something he expected to see with logic board replacements and hadn't seen it caused by software - but same fix (which took about 5 minutes) worked.

Battery didn't drop at all last night, so 10.14.1 fixed whatever was causing the battery drain with mine.

"sharingd is sharing daemon that enables AirDrop, Handoff, Instant Hotspot, Shared Computers, and Remote Disc in the Finder."

My Macbook 12 (2017) shows sharingd and backupd prevented sleep… this after 10.14.1 Mojave updated….

Still waiting for a solution from Apple…. the only one i found is shutdown instead sleep during the night...

Hello all, I have the same problem with my macbook pro. I have a MacBook Pro (Retina, 15-inch, Late 2013). After installing Mojave a few days ago I noticed that the laptop's battery has been raining faster than usual. I timed it and the battery drops about 1% every 4 or 5 minutes. That was not the case before the update to Mojave. As an example. I turned the laptop on at 09:00AM with the battery at 100%. It's now 9:25AM the battery is at 94%.

The work load has not changed. I'm using the same apps I normally use: Chrome, PS, LR, Skype. Nothing out of the ordinary.

My girlfriend has the same exact laptop running Mac OS Sierra, with the very similar work load and she doesn't have this problem.

My guess is that Mojave's got a bug that's causing the battery to drain faster than usual. Hopefully the Engineers at Apple with hear about this problem and release a patch soon.

As it's now I can't use my laptop without plugging it up to electricity. This is very frustrating.

Thanks.

ps. If Apple need I'm willing to share usage and system reports to help debug this thing.
