Incredible battery drain in new Ventura 13

I am also having the same issue. I basically tried every solution available online to fix it, including reboot smc and also checked activity monitor. Everything is useless, everyday I wake up my MacBook Air m2 on Ventura 13.2 is totally dead or only left a few percent of battery. Apple please fix this problem. I have no any other way to fix it and I rely on the MacBook so much for my work. I will try to turn off the bluetooth and put it to sleep tonight to see whether the issue can be solve or not. I haven't tried to contact the apple support team but I think I will soon. I hope this issue get fixed soon. APPLE PLEASE DO YOUR JOB!!!!!!!

How can Apple rollout an updated OS and not do adequate regression testing on all platforms to ensure that a MAJOR BUG like this doesn't get out to consumers? I'm really losing confidence in the Leadership Team at Apple at this point and I probably won't buy another laptop from them in the future. Come on Apple, wake up and fix this FUBAR problem that YOU HAVE CREATED and are obligated to correct!!!

I could fix it by disabling all apps in Settings → General → Login Items → Allow in Background.

I guess macOS now has an app API to wake up Apple silicon macs like iOS background refresh.

To remove apps altogether from this list, I ran Etrecheck to identify where they are located.

So wanted to let y'all know how I resolved it:

1. Bluetooth disabled upon sleep.
2. Found this by using a utility called 'Sleep Aid'. It allowed me to detect what was waking the machine in a visual form and then also reset the sleep settings to whatever I wanted, again, in a visual form. You can google 'sleep aid mac' and find it. The trial was adequate but I paid the developer for it just because it solved the problem.

Have had 0 issue since. 100% battery upon closing the laptop last night, 100% upon reopening it this morning.

Ventura 13.3. MacBook Pro M2 13".

Apple needs to ship a utility like this with the operating system.

How do you downgrade back to Monterey?

I had the same issue, draining battery in sleep mode, and I found that Google Updater background item was draining my battery. In case you also use Google Chrome then you have this item too. To disable it just search in spotlight for Login Items and from the settings page toggle off Google Updater. Please note that this will prevent Google Chrome to update automatically.

I thought they fixed it. But i still see significant battery drain during shutdown (~2.8% per hour). The computer shows 100% while charging. After 7 hours of shut down state, it only shows 78%.

Apple seriously needs to fix it pronto.

Apple M1 2020 13 inch MBP 16 GB RAM and 500 GB HDD, running OS 13.4.1 Ventura.

Apple 13 inch M1, 16 GB memory

2020 Model.

1. Downgraded to Monterey No effect
2. Upgraded to 13.3 still no effect

Losing charge approx. 3% per hour consistently. Bluesnooze installed. Manually disabling Wifi during sleep or shutdown.

Even when shut down i am losing battery charge.

Battery status shows normal.

Same issue here. Was using Ventura 13.1 on Macbook Pro M1 2021. Battery started draining at one point. Downgraded to Monterey and it was a better, but not perfect. When Ventura 13.2 came out I decided to give it a try, but now it is draining again - around 25% for less than 24 hours in sleep mode, closed lid. This is really annoying. I am thinking of giving back the laptop and use the warranty. Anyway, I am glad that there is a topic here that we can discuss about this issue, let's hope they fix this with an upgrade soon...

I have the same issue when I upgraded from my MacBook 2020 M1 chip with Monterey to my new MacBook M2 chip Ventura. Already had contact with several service agents from apple but they did not have a solution so far

Apple - do you have a solution??? Spent countless hours with your support team reinstalling the operating system etc etc.

I tested in sleep overnight - down from 100% to 70% with nothing attached. Something is terribly wrong with Ventura.

I have tried to reinstall it and all that jazz, no luck.

Will we really have to go back to Monterey???

I also have this issue. It's crazy. The laptop drains in 24-48 hours of not using it. M1 max 14" here. This didn't happen with Mac OS Monterey. It started happening after I updated to Mac OS Ventura. It was less noticeable on 13.0. It's wayyy worse on 13.1

Actually, I have switched off Bluetooth and left it off - I don't use it. But agree it's not a viable solution for those who do use Bluetooth - Apple need to update the behaviour of Bluetooth in OS Ventura.

Do you have screenshots for what the wake calls look like? I'm running 13.2.1 (22D68) and have had the battery drain during sleep resolved, but am now experiencing a much faster and consistent decrease battery during basic tasks (Pages, a couple Safari tabs, Spotify streaming) more similar to what I experienced running heavier tasks (Lightroom and Photoshop image editing, SketchUp model building, etc.) pre-Ventura.

Prior to updating, those basic tasks would sip on the battery life and I could go 2-ish hours with a 10% drain. Now it seems like battery is going down 1-2% every 5 minutes. Even now just writing this post with only 2 Safari tabs open down from 94 to 92%.

Marginal I know, but I'll need to work off a similar machine that's still on Monterey to confirm this drain.
