After I updating my macOS from Monterey to Ventura I am struggling with an incredible battery drain in sleep mode. I've already tried to change many options and even closed all my apps before entering a sleep mode. What I noticed in Activity Monitor is the fact that both kernel_task and WindowServer use a lot of CPU % and make a lot of wake-ups, but I suppose it is ok. Do you have the same issue with a new system?
MacBook Pro 13″, macOS 13.0
So wanted to let y'all know how I resolved it:
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.
I think apple resolve it, I upgraded to Ventura 13.2.1 then the battery drain overnight problem is gone
Just turn off the Wifi before you close the lid and you should be good.
Please update to venture out 13.2 and let me know if that changes anything, I went back to Monterey.
hi, is the battery drain gone after you switch the bluetooth off? or is the issue still a problem but just less significant with the battery drain?
thanks for the help
m1 mbp 14 inch. i turned off "handoff" and gonna try tonight to see if it makes a difference
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.
For months since Ventura update, i was facing incredible battery drain (see my posts in the same thread). I have kept the mac connected to power supply as removing it drains to dangerously low battery (2% or less). Some times it becomes so low over two days that it wont power up even after connecting to power supply. My usual battery drain rate was 3.3% per hour. so i lost around 50% to 60% over 18 hours time.
After updating to 13.4 i still faced the same issue. So kept the power supply connected day and night for several days. Never disconnected. I started observing that the mac started to feel warm (in shut down mode) even when power is connected. This was new. Earlier it used to feel warm when power supply disconnected (in shut down mode). So i decided to test and disconnect power supply after shutting down.
Today first time in several months my M1 mac book pro battery drain is less than 20% even after more than 18 hours. I think apple has fixed it. I am closely monitoring my M1 if it is a one day phenomenon or it is going to hold.
Apple menu -> About this mac -> System report -> Hardware tab
Unfortunately, Apple remote service is a kind of drama. I do not know... they are even worse than Manta service or similar ****. Those people there are really a joke. I've been fighting with them for over two months now. I do not even want to think what kind of support I can get in case of a serious problem. I am already tired with Apple. I think this is my last Apple device :( Never ever...
We had many contacts agreed last weeks and nobody called me so far... not even once. The only thing they can say when I call them is "We are sorry, we are doing our best" or "Our service technician will call you tomorrow, day after tomorrow ble ble ble" and of course all those promises were just ********.
Already do not know what to do... I cannot pass my Mac to stationary serve as I need it for work.
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
I took it to an authorized apple support in my city. Spent 5 days there and they said the problem couldn't be detected during their tests. Result: Back home with the same problem. I tried to show the employee the battery data in settings, so he can see the battery drain in sleep mode. He said he was going to talk to his superiors and call me when he finds out something. He didn't know what to do.

I found this...If any one has tried, let me know if it works. I am going ahead with this for now. will post here if it works and prevents battery drain.
Apple 13 inch M1, 16 GB memory
2020 Model.
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.
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.

Incredible battery drain in new Ventura 13
