Updated MacBook Pro to macOS Sonoma, now battery drains quickly

I have exact same problem. Can you advice if downgrading OS or wiping out everything can help? Because it's really frustrating, I loose like 1% every 5mins of just browsing(compared to past I had like -1% in an 40-50mins maybe)

Your response is pretty generic, and not specific to Sonoma 14.x. After upgrading to 14.1.1, I see a significant drain in battery power, and it also messed up my system clock!! It would not let me update the system clock, nor sync with a new time server (time.nist.org), even after I su as root.

Moreover, I was doing whatever I was doing prior to the upgrade and less, so your response about battery drain doesn't make any sense. Can you give a good technical reason why the battery drain in temporary...why only a couple of days? I upgraded to 14.1.1 when it was out on 11/07, and I see these issues (battery drain/system clock) since yesterday! Apple, do you copy?

Thanks for the reply, but I don't think so. Look at the sheer number of people who are having this same issue--suddenlty. My battery was NORMAL before Sonoma. I'm not going to put any money into this until the next update.

Also, why would it indicate right when it wakes up that the battery is at zero and then when I plug it in, the battery percentage indicator jumps up to where it should be albeit 30, 60,80 or 90%. I have had it do it at various charged levels.

When I unplug it, it holds a charge while I am using it. The only problem is while it's sleeping and then waking up.

Because of this issue Apple owes me a new sofa, LOL. Here's why. I left my laptop on my leather sofa and covered it with a blanket accidentally and next morning my laptop was glued to the sofa leather because of the heat. More heat got trapped because of the blanket. I can see the discoloration on the sofa where the laptop was lying overnight. Kinda ruined my sofa.

I would resist suggestions, even coming from Apple, to do clean wipes and resets of your devices. Apple recommended I do this when my iPhone was suddenly hanging up calls. I asked for alternatives. The Apple Store Genius Bar didn't have one, so I came home and searched and searched on Communities and found how someone noted by turning off Siri's ability to hang up calls in accessibilities, it solved the problem. It took several days of looking.

Same thing here. Keep looking at people's suggestions before performing a dangerous maneuver like erasing a Mac and starting over.

I agree however, I just noticed Sonoma 14.1. Does this update do any difference? It doesnt say anything in the release notes as in: lets just quietly add a fix for the battery while addressing a bunch of other stuff.

I can confirm this has nothing to do with any background process. I have left my Mac on for days just to make sure it finished whatever it needed. I can watch my batter drop 1% every 5 minutes or so. With zero activity.

I further made another update to 14.2 , and WOW, Battery from 100% plugged went to 80% in less than 30min, yes you saw this right, I lost 20% of my battery while its plugged already while I'm just coding using two monitors:D

Is anyone from apple could just say anything?

That's exactly what it is, optimised charging mode. You should be happy that that mode is working in your Mac. Your Mac/macOS is doing its best. to save your battery while plugged in all the time. 👌

I also feel battery drain faster in my MacBook Air m1 after upgrading to macOS Sonoma earlier when I use safari for 2 hours for video playback it drain only 4 to 5 % battery but now every hours drain almost 8 to 9% battery

why is it?

100% agree. Sonoma is garbage code. Whatever they are TRYING to do with it, they need to STOP and give us our battery life back. Losing 30% of the battery (from 94% to 64%) in 22 hrs of sleep mode is NOT acceptable. The whole reason I switched from a windows laptop was because of battery life. If you can't fix the code so that the battery doesn't drain, I may as well switch back to cheaper windows laptops. Spend some of those billions you guys are making on better code!

Same here, running hot, draining battery extreemely fast. I am running 14.1.2 and no better for the upgrade to Sonoma. I used to be able to run on a charge for at least twice as long. It even drains with nothing running and with the screen closed. Come on Apple, enough is enough.

Updated to macOS Sonoma 14.2.1 few days ago, and I too am experiencing a massive battery drain on my new M3Max 14" Macbook Pro. I think the battery shouldn't be draining this fast with only few applications open. Apple technicians need to review this issue, and a fix patch should be given right away. This may ruin current users' investments in the long run.

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 came here to complain about the exact same thing... updated yesterday while it was on charge and 100%, when it completed it said my battery was then 1% after I removed the charger. I charged it and then turned it off (not sleep) and just opened it today to work and again my battery is 1%!! And it also needs a servicing?! How good of apple to then suggest its nearby shop locations so far away.
