What does coconutBattery report in specific regards to Designed Capacity versus Actual Capacity of the Battery ?

Hi guys, I have this macbook pro 2020, m1 13". Eversince I got the mac os sequoia, my mac has been heating up terribly and the battery runs down so fast. Today I fully charged it and just left it open although it was asleep and now that I want to work, it's indicating that the battery is low. This sucks. Also while charging it and working on a word document it heated up so bad it felt like I was rendering a 6hr video. I miss big sur

Now avalible Macos 15.4 RC 24E246

Critically, something still hasn't been fixed:

the battery in sleep mode simply drops 5-10% overnight. It's a tin can. I install Sonoma - and the battery does not go away there, 0%. Sequoia 5-10% drop per night. This is a big expense in sleep mode. The graph shows that the mac does not go into sleep mode normally. It urgently needs to be fixed.

I have a stock system, without third-party software.

Is Apple serious? 15.4 and it's not fixed? Finally do something about it.

Hi. My MacBook Pro 2019 have a same problem after sequoia update. Battery drain after shutdown. During sleep have a same situation. Etrecheck report is here; Please help me. Sorry, my English is weak.

Once it cools down & charges up, try one of these two..

Are you running any VPN, Anti-Virus, or Cleaning apps?

We need to see what all is running, a report from this will not display any personal info...

Or as a test... Safe Boot...

Start with this of M1 or M2 Mac...

On your Mac, choose Apple menu  > Shut Down.

Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.

Press and hold the power button on your Mac until “Loading startup options” appears.

Select a volume.

Press and hold the Shift key, then click Continue in Safe Mode.

The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.

Restart normally.

Start with this if IntelMac...

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

To find out if it's system wide or user specific, try this...

Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

Does it work in the new account?

Hello everyone,

I wanted to share the steps I followed after contacting support to address the rapid battery drain issue, which worked well for me.

1. Restart your MacBook in Safe Mode.
2. Create a new user account on your MacBook.

• • Skip any non-essential setup steps and let the system load to the standard desktop.
  • Do not connect Apple ID

1. Restart the system and log in to the newly created account.
2. Shut down the MacBook again.
3. Connect the charger and charge to 100%.
4. Start up the MacBook and check the battery life in the Activity Monitor to see if the issue is resolved.

Cheers!

I always take care for the macbook charging system and the used programs for optimisation.

I'am really sad because it is a spectacular changes and not the good way.

It sounds like you try to take good care of your computer, which is good. I think Etresoft and PRP have the best perspective on this and possible solutions; downloading and running Etrecheck and posting its report as a reply here will likely reveal some possible causes and fixes.

Here are some things that can consume battery quickly. Sometimes they are "ok" with an older version of the MacOS but then start using inordinate resources after an update or upgrade, for reasons that Etresoft mentioned. I don't know if you have these things running, however:

• Anti-virus or similar "security" tools: these run in the background, even when the Mac is sleeping, not only do they use energy and resources checking every single byte of data that is moving through your Mac, but they run scans overnight and in the background. My employer requires a specific anti-virus tool to be installed in all its Macs and PCs and at times the fans pick up because it is scanning and that can use a lot of energy (battery), especially if it is not well adapted to Sequoia.
• Internet or network security apps -- also running all the time in the background, some even when Mac is sleeping, they inspect every bit of network traffic, sometimes writing logs or whatnot.
• Cleaning or optimizing apps, same problem as above, checking things in the background
• If programs are left open (running) when you put your Mac to sleep, it may wake for network access. Software like Microsoft often check with the home server for updates; especially suspect are browsers, which may have web sites open that are actually running videos, animated ads, etc. These can consume large amounts of energy and Mac resources, especially if many tabs or windows are open. It may be that some of these browsers run differently under the more recent versions of the MacOS.

You might get some clues from Activity Monitor, maybe shut down and restart your Mac right before putting it to sleep, then next day when you wake it up, look to see which processes were using energy, disk activity, memory, cpu time, etc. during the time you thought it was sleeping.

As Etresoft indicated, some software may run differently under Sequoia than they did under earlier MacOS versions. I think that responsibility lies with the vendor of the software, to make sure it is compatible with MacOS.

Same here, my M2 draining faster after updating

Same case with me and my 2017 Mac is working better as it cannnot be upgraded further than my latest 2021 Mac.

I have a work Macbook M1 and the battery that used to last around 5 hours or more now lasts 3 hours or less it's so frustrating and annoying

This is universal problem which doesn’t have solution as of now!
