MacBook M3 battery drains significantly after shutdown following OS update to version 27.0

Since updating my MacBook M3 to OS version 27.0, the battery level drops to just 60% by the time I arrive at work the next day, even after shutting it down before bed. The casing also feels slightly warm to the touch (suggesting that processes are continuing to run in the background even after the OS has been shut down). I am wondering how to resolve this issue.

Are you sure the laptop actually powered off? Many times some app or process can prevent actual power off leaving the computer running.

Also, even if the laptop powered completely off......pressing any key or even the Trackpad can cause the laptop to wake up or power on. And connecting/disconnecting external devices may do so as well.

I personally like to press the Caps Lock key so its LED lights up so when I power off the laptop I know it is completely powered off when the Caps Lock LED goes dark. Of course if you accidentally power on the laptop by pressing a key or Trackpad, then it doesn't matter.

You can use the following Terminal command to see whether the laptop was actually fully powered off during that time, or whether it was still powered on. You will need to copy & paste this command since the spacing in the filter section is critical for getting the correct minimal results:

pmset  -g  log  |  grep  -E  'Sleep  |Wake  |Start  |ShutdownCause  |Notification  '

Pay attention to the date & time stamps. If the battery has a problem, then the system may not log all of the information.

As @Grant mentions, leave the laptop connected to power whenever you can.

When you set it down in one place, or set it down for the night, Plug it in. Then you won’t CARE whether it would drain the battery. 

當你把它放在一個地方，或是晚上放下時，再插上電源。這樣你就不會在意會不會耗盡電池了。

Since the OS of MAC Book M3 rose to 27.0, it shut down before going to bed at night, but the company's power was only 60% the next day, and the shell was slightly warm (it felt like there was a program on the ground floor that was still running after turning off the OS). I don't know how to solve this problem. problem?
