Has anyone else had this strange problem with their MacBook Pro not going to sleep when closing the screen since updating to macOS 10.15.4? Since the update I have noticed that overnight the battery would drain 25-30% with the screen closed, where prior to the update, there would be little to no battery drain. I have rebooted and also did a SMC reset and no change. I’ve tried selecting sleep prior to closing the screen and still no difference and 20-30% power drain overnight.

Any ideas for a fix?

I have same issue with among other crashes with my new MacBook Pro 16". I asked apple for a replacement.

In my case I could see that the machine wakes almost every minutes.

# to clean up old logs
sudo log erase --all

# close the lid and wait 10-15 minutes
log show | grep 'Wake reason'

Strange thing is, it didn't happen in a different WiFi network!
