Battery Life Issue After macOS Sequoia Update

Hi Mac mates, I have the same problem here, so sad!!!! I have a MacBook Pro M3; before updating to Sequoia, the battery lasted more than 8 hours without plugging in the power. Now it lasts 4 hours, more or less. Also, before updating to Sequoia, the laptop didn't take battery when suspended, but now I put the Mac in my backpack, go to work, and surprisingly, I find the battery down. WHAT IS HAPPENING??????

I have the same problem on a new 15" M2 Macbook Air bought in July of this year, it has barely 10 charge cycles and before the update to Sequoia 15 it consumed 2% in 2 to 3 hours of light use, now it drops 2% every 30 min! This is unacceptable

I have already followed the recommendations described here such as checking that there are no high consumption programs or leaving it on connected so that it can reindex after the **** update and still nothing.

The battery is consumed even when suspended and stored in its case, so I have chosen to turn it off completely between each use.

I experiencing the same issue for my MBP 15 2018. Shut down laptop with fully charged battery, but when i turn on the day after, the battery only left 5% and after charge for 5 minutes it is become 77% charged. Important battery issue (Battery service recommended)also appears on system setting.

I have the same issue. I turned off the computer yesterday at 8pm with 100% battery. I turned it on the next day at 1pm and it had 5% battery. Once I plugged it in the charger, it went to 57% instantly.

The same problem on my m3 pro. I noticed that my laptop often turns on the screen at night, maybe this affects

The same issue on my MBP 13" Intel 2018. Battery level drops by 2% every 15 min. Ventura doesn't have such an issue. The issue appears on clean Mac OS Sequoia installation thus it is not 3rd party problem. I have reset SMC and PRAM also. Nothing changed.

May be some incompatible service is causing the issue. I had the same issue with my M1 Macbook air after the Sequoia update. For me, it was an old (not fully compatible with the latest OS I guess) web cam utility that was causing the issue. Uninstalled it and looks like it's back to normal.

Open Activity Monitor > Energy Tab. Sort by Energy Impact.

Stop/Uninstall the one that's impacting (highest number) the most.

So this is the situation:

1. Sequoia 15.1 drains the battery
2. Sequoia 15.2 preview does not address this fundamental issue, pushing "intelligence" related features instead (more drainage ahead)
3. Apple does not even seem to acknowledge the issue

Sorry, I need battery life more than "intelligence".

"Downgrading" to Sonoma now. In fact I'll call it an upgrade. I'll further use sequoia on the other, desktop Mac (which is on AC all the time) and see if and when Apple comes to sense.

Okay, first off I’m glad others have reported this issue. Have a MB Pro 13” 2020 Intel i5; been working phenomenally for last 4 years, until recently - now my situation’s a bit unique, dropped a few drops of water near the right charging port but before liquid could penetrate wiped thoroughly, Mac’s been working fine since, ports as well, but since I was being overtly observant, I spotted the fast battery drainage issue (2% every 15 to 20 min). Ran an Apple diagnostics, all clear. Was wondering if I should reset SMC / NVRAM? I had updated to Sequoia few days prior btw.

Would appreciate some input my fellow Mac-ers 🙏🏼

It is. I just did that, as announced earlier.

1. I'll tell you if the draining rate has improved after the downgrade (in a few days), confirming or not that Sequoia is a battery drain
2. downgrading will only work if you do a fresh reinstall, using a bootable device loaded with Sonoma install app.
3. If you try using a Time Machine, you'll get an error message telling, in substance: "impossible to downgrade from this version [Sequoia]". The Time Machine will only allow you to restore your apps and date.

The procedure takes some time and manipulations - backing up, erasing and reformatting your hard disk, downloading Sonoma installer from the App Store (free), retrieving your wifi password (wifi is required to register your machine again), apple account password and machine password - but otherwise simple and uneventful.

Most likely, there is some 3rd party system modification software that is incompatible and causing too much energy and CPU usage.

Facing the same issue. After sequoia update my Mac lost 2% in its battery life and it's not even 5 months old yet. Apple didnt help me a lot with this. It's a very concerning issue because Mac batteries are supposed to last a long time. I am down only 30 cycles and life is already at 98%.
