Updated MacBook Pro to macOS Sonoma, now battery drains quickly

It's been several weeks and I still have my battery drain completely almost every time I leave my laptop closed for a few hours. I pull it out of its zippered case and find it hot with the fans running. If it was just indexing associated with the new install, it should have been done by now.

I've posted before that I saw improvements to battery drain like alperevren has seen. Checked to ensure no processes prevented sleep. All good, but then... One of my Intel MBP totally drained battery overnight again :-(.

So one cannot trust sleep for long periods of time otherwise it will cause issues with battery life. I have never had this issue with any previous OS on the many MPBs that I have owned. It totally renders this product as useless, because it cannot be relied upon when you need to work on battery power.

I would urge everyone to go to the support page and log the issue with them.

I pity anyone with a brand new M series machine that is seeing this poor performance. If I got s brand new machine and had battery discharge rates as described above I would be heading to the Genius Bar.

The thing is, when you upgrade, you should go through every section of the System Settings after the upgrade. Some new options could be added, some other options might be taken off. Also, if your Mac is near an electrical socket, it would be advisable to plug in the Mac, before putting it to sleep, with optimised charging mode enabled👌

Just turn on low power mode or redownload Mac Sonoma, or just downgrade to Mac os ventura.

Indeed, it can be quite frustrating. I've recently downgraded to macOS Venture, and I don't intend to update it again until the battery issue is resolved.

System Settings > Login Items > check if you have any app working in the background. Disable and delete anything there. Also, System Settings > Battery > Options >

Yes even I am facing the heat issues all of a sudden and faster battery drain after updating my macbook air m1 to Sonoma. I waited for somedays but now it has already been a week. I never faced any heat issues before this and the battery backup so good. Will there be any update coming in the future to get it fixed?

Experiencing the same thing. There is an x on my battery and it has been on 1% since last night.

I use the 2020 M1, and for the first time in 3 years, I hear the fan. The fan comes on as soon as I switch on the macbook

An "X" on the battery icon indicates a hardware issue of some sort with the laptop. Have Apple or an Apple Authorized Service Provider examine the laptop to provide you with a repair estimate.

My laptop battery also drain >10 times faster than before upgrading to Sonoma. Not only draining my battery but also heating my laptop in a temperature like "almost explode". All happened even in sleep mode!!!

Can Apple fix this as soon as possible?

Can't imagine this happen at the same time both on iOS17 and the Mac. What happened on your UAT?

I am so regret upgrading to this version. Not much useful improvement but took away what I used to have.

I also have a MacBookPro 2019. Wait a few days? For what? The situation has been going on for 5 days, I call my laptop every day for min 8 hours. And every day in the morning I open it with 1% battery - is it a joke? Everyone takes water in their mouths.

I understand your point of view, but not every mac has Sonoma installed. Not everyone knows this discussion board. Perhaps these 20 people in this discussion represent millions of mac user who don't know why their mac suddenly consumes more battery than before.

People go on a support page to ask about a problem they are experiencing, in hopes of receiving support with the problem they are experiencing. No one here is saying “everyone has this problem”; they are saying “I have this problem, are other people experiencing this problem, does anyone have ideas as to the causes or solutions?”

Your response is analogous to telling someone that shows up at the hospital with a broken foot that millions of people have feet that are not broken, so they should quit their whining and accept their lot with the broken foot minority.

Now past the three week mark and still the same issue, so it's definitely not the "just give it a few days to get through indexing" thing. Things that I have tried that have not had any effect:

• Restarting right before putting it in standby
• Deactivating discretionary background processes (e.g. autoupdaters, 1Password helper)
• Turning off location services

Typical drain is around 30% overnight in standby. Like others, Activity Monitor shows no screen time during that period. App Nap is set to run only when connected to power. Running a 2020 Intel MBA.

This looks very promising. I charged my 14" Macbook(M1) to 100% at 11pm, turned off wifi and put it into standby. Today at 6am it still shows 100%. Because i'm at work now, i'll look at the battery status again in the evening.
