Updated MacBook Pro to macOS Sonoma, now battery drains quickly

I have exactly the same experience with my MBP M1 Pro 2021. I would unplug my laptop from the charger and the next morning it would not turn on until I plug the charger. The battery is at 1%. This has never happened before.

I can't believe that Apple still haven't sorted this out!

Experiencing the same thing. There is an x on my battery and it has been on 1% since last night.

I use the 2020 M1, and for the first time in 3 years, I hear the fan. The fan comes on as soon as I switch on the macbook

An "X" on the battery icon indicates a hardware issue of some sort with the laptop. Have Apple or an Apple Authorized Service Provider examine the laptop to provide you with a repair estimate.

"Anyone else"?

Not us. Our 2020 MBP seems to have greater battery run time than with past OS versions.

We're really enjoying Sonoma's new features and responsiveness on our three Macs with Sonoma.

I wonder what the variable here is as it apparently made it past whatever (limited) testing/QA they do these days.

I initially thought it may have been an Intel vs M1 thing, but that appears to not be the case.

ALSO ME. Also M1 MacBook Air. Also well after a week.

Does this OS prioritize newer computers?

I'm having trouble even figuring out how fast this thing is draining - it seems to be every time I pick it up it needs to be put back on the charger. Unreal.

that is just the same line that get repeated every time somebody reports battery drain on their device, let it be a macbook/apple watch/iphone…

It is always because indexing has to work its way out because of an update or reinstallation, as if most people don’t comprehend such piece of knowledge. 😂

I had this problem and it's fixed by reinstalling Sonoma OS.

My battery consumption used to be 10% / hour pre Sonoma, and then 25% / hour with Sonoma. I reinstalled Sonoma as told by Apple genius and the problem is now fixed.

People asking if anyone has the same problem that he has. I also have the same problem. What should we do, wait and do nothing? You keep enjoying Sonoma features!!!

Anyway, I have the same problem despite this guy (ku4fx) doesn't have and enjoying his Sonoma. I checked the activity monitor and iPhone 15 Simulator was using lots of CPU percent. I closed it and then seem to go back to normal as per heat. But battery drain I haven't checked it yet. For my case probably Xcode is causing the problem. We will see.

I have the same problem. I have Macbook Air M1, and i have installed Sonoma for about 2 weeks. From the start i have noticed, that battery drain is much worse than before. Its like 3-4 time faster, and im still doing the same things on laptop, mostly browsing.

I'm not using Sonoma wallpaper, don't have Music of Timeface icons in dock and still have the problem. I think this will be some deeper issue. I have almost fresh macos install with only few basic apps and still have this problem with battery draining.

I have updated my MacBook Pro 14 inch (M2 Pro) and after updating it to MacOS Sonoma, the Battery Drain Speed has increased, like I use it for professional video editing using FCPX then also the battery drain is so much that I need to charge my mac Twice a day.

Is there any fix/workaround to slow down the battery drain ?

I have successfully resolved my issue by downgrading to macOS Venture. If you're looking to perform a similar downgrade, let me guide you through the process. If you already have a backup, you can skip the backup creation step. However, if you don't have a backup, you can use a USB pendrive or an external hard drive to create a backup using Time Machine in your system settings. Before you proceed, ensure that you format the pendrive or hard drive.

Here are the steps to downgrade to macOS Venture:

1. Download macOS Venture: Get the macOS Venture installation file from a reliable source.

2. Create a Bootable Drive: You'll need another pendrive to create a bootable drive for the previous macOS. You can find step-by-step instructions on how to do this on YouTube or other online resources.

3. Prepare Your Mac: Shut down your Mac and hold the power button for a few seconds until you see the boot options.

4. Access Disk Utility: In the boot options, choose "Disk Utility" and erase your Mac's hard drive entirely.

5. Install macOS Venture: After erasing the hard drive, hold down the power button again. You'll see various options, including the option to install macOS Venture. Insert the bootable pendrive you created earlier and select this option. Follow the on-screen instructions to install the previous macOS.

6. Restore Your Data: Once the installation is complete, your Mac will be in a fresh state. Open the "Migration Assistant" and insert the pendrive containing your backup. Follow the prompts to restore your settings and files. This will bring your Mac back to its previous state.

I hope this guide proves helpful to someone experiencing a similar issue.

same here. i'm chatting with support to see if they have any typa boot-time solutions. but i'm pretty sure this is probably something apple will need to release an update fix for. it's probably buried deep in the system code somewhere.

#Update:

they mentioned that after an update, there's a 4-day window where processes will drain batter faster. then, it should return to normal. but if it's been longer than that, it doesn't apply to u.

MacBook Air 2020 (Intel) here. Same problem. I upgraded 10 days ago.

The Mac was unplugged around 4 PM (and I closed the lid and stored it away), as can be seen in the attached graphic (plugged in battery, screen usage). I see there is a significant drain until 5 AM or so.

I can't seem to find the problem. Any thoughts?
