Updated MacBook Pro to macOS Sonoma, now battery drains quickly

Battery drain. UNPLUD EVERYTHING FROM THE MACBOOK, external screens, even the power cord! I have a 2018 MacBook Pro with original battery. Loses 1% only over night. UNPLUD every cable in and out of the computer.

i also downgraded to mac os Ventura and everything went back to normal.

This needs to be fixed. Should have just stayed with Ventura ....

I think I may have solved the battery drain issue on my two Intel based MacBook Pros. Both MacBooks are no longer warm when sleeping which was never observed with previous OS versions. The sleep battery drain seems to be acceptable now as well.

Here is what I did:

1 - updated to Sonoma 14.1.1

2 - disable Bluetooth

3 - disable power nap

4 - disable Wake for network access

5 - in terminal use: pmset -g | grep -w sleep

This command will let you know if any processes are running that prevents sleep. In activity monitor I stopped the suspicious looking ones. There was one in particular that was always running even after reboot. If you just turned the power on, you will need to wait for the startup processes to finish.

6 - By repeating the pmset -g | grep -w sleep command you will see that eventually there will be no processes blocking sleep.

7 - To test if it is working, go to Apple and click on sleep. Come back a couple of hours later and check your battery level status chart in the System settings. It should show a very shallow slope on the discharge curve:

I did a full disk wipe, and reinstalled Sonoma from a USB boot drive and my battery is still markedly worse then Ventura

I would agree with the statement of a complete wipe not solving battery drain. Performed a complete wipe on two machines both of which exhibited high battery drain even after.

Ok, my battery is officially done. It wont start without being plugged it and dies as soon as I unplug the usb-c/unplug it from the wall.

No doubht that this is a Sonoma issue.

Is your conclusion that wireless connection could be the culprit Or is it the power nap/wake for network?

Not for me it didn’t.

No the new version makes the problem even worst.

@apple Can you please fix the issue?

Brand new 16" MacBook Pro M3 Max (running Sonoma 14.1.2 out of the box) - unboxed 3 days ago.

Had below battery drain kick me in the nuts this morning. Went from ~90% to <10% in around 1.5 hours. Nothing significant running at the time.

Assume I had put on max load graphic/computation (again, which I did not have at the time): brand new (and pretty much fully charged) battery should still have longer runway and this (right?)

mine is a mess too, just turned mine back on and the battery went from 35% to 1% and died in 2 minutes, I plugged it in, it woke up and now the battery says 40%, makes no sense at all

Battery drain is a real problem and it's really surprising that Apple had done nothing about this. What's also surprising is the lack of research that goes into releasing new software and updates.

After a number of weeks since posting and upgrading to 14.2.1 the battery drain seemed to have gone away. But then the other morning it was at 2%. Looking at the battery log showed that something during the middle of the nigh came on and drained the battery much faster than I would have expected. :-(

Bit the bullet and did reformat and installed Ventura. All issues of battery consumption are gone and it is working as we all expected from the product. Here is the amazing log that puts Sonoma to shame:

This is the very common issue that every third is facing in the world. The battery backup is sinking slowly by slowly without any use. I can't get solutions till right now.
