Battery Draining Fast since Tahoe upgrade

I updated my MBP (M3 max) a week ago my battery is draining crazy fast too, havent tried anything yet im sure it was right after the update.

Thanks. Think I might do the same.

I agree with your situation. My MacBook Pro M2 Max has just not been the same since 26 and subsequently 26.0.1 still doesn't improve the battery.

Wow, so I should wait for a day or two. I thought of returning my new MacBook because I can't use. Wanna purchase a 32gb flash and downgrade to 15.7 Seq.

Calling a MacBook “battery-capable” is a stretch. If 26.x made battery life this bad, that’s a bug. “Just plug it in” isn’t guidance, it’s avoidance. Help me find the cause.

yeah, this is heinous work. these past weeks went from 12+ battery life hours to 3 at best. It is absolutely insane. they just obliterated my battery performance

Yes and it is a real pain. 14 in M1 MacBook Pro. Very frustrating -- Apple seems to have left a lot of us in the lurch on this. Will try the adjustment you describe, go from there.

That should be expected while spotlight is indexing files in the background and optimizing object detection on your photo library after an update. Give it 3-4 days and leave the Mac plugged in when near a power source. Large Photo libraries may take a day or two longer.

It really should not take long to index files with the speed of the M4 as long as the computer is not shut off to prevent it from indexing.

"I have a 14-inch MacBook Pro with an M4 Pro chip, 24GB of RAM, and a 1TB SSD. Ever since I updated to macOS Tahoe, the battery has been draining incredibly fast.

And you know what? I've been leaving it constantly on, just putting it to sleep by closing the lid. The whole story about Spotlight indexing is nonsense. It's not indexing anything. The OS version is just raw and unpolished.

My MacBook only has 54 charge cycles, and it's already reporting 99% battery health after just one month of use. For comparison, my 2020 13-inch M1 MacBook Pro went down to 87% after five years of use. What are you even talking about? This is ridiculous.

I bought an external hard drive just to offload my terabyte of data and go back to the previous OS. This whole situation is absurd, and Apple support is no help at all. Today, I started working at 10:45 AM, and by 2:50 PM, the battery was already down to 17 percent. I was watching the percentage drop right before my eyes."

I have 26.1 and am still having the issue. 16-inch MacBook Pro M4 Max on Tahoe 26.1. Issue was bad with 26, but is pretty much the same on 26.1. I also have slack, which I'm going to try manually quitting next time I let it sleep unplugged. It goes from fully charged to zero overnight every night since Tahoe if it is not plugged in and also is getting exceptionally hot during charging sometimes. It's been on Tahoe for plenty of time to have completed all indexing.

I tested this theory and I was watching movies, for 30 mins it took a 7% battery.

After I closed slack, chrome, and VS code. for 1 hr it only took 6% battery.

Same here. The battery drain rate is unbelievable. How can one go back to the previous version OS?

Same thing. I found that “duetexpertd” was running between 80-150% CPU. I called Apple in November and they couldn’t figure it out, so I reinstalled Sonoma and all the problems went away.
