After updating to macOS Sonoma my MacBook Professional 16″ 2019 would not enter standby mode even at evening after greater than 10 hours of being closed.

pmset -g assertions exhibits the next:

Google says, that there’s nothing irregular. I’ve set the next settings in pmset
very long time in the past, and earlier than replace all the things was positive:

System-wide energy settings:

One can see standbydelayhigh to be equal to five hours, therefore, the laptop computer is predicted to
enter standby mode after 5 hours of sleeping, nevertheless it would not:

The image exhibits a battery statistic for an entire time frame. Earlier than replace this statistic had a niche, as a result of it was not collected throughout standby. Yet one more proof is that there’s a catastrophic battery drain of 5 or 6 percents, i.e. the laptop computer consumes energy whereas being closed. Earlier than replace the battery proportion decreases by the identical 5 or 6 percents throughout a a number of days (examine with one evening after replace).

Moreover, earlier than replace I’ve to press an influence button after opening a lid, as a result of the laptop computer was in standby mode. Now the display screen wants a only a few time to point out lockscreen with out urgent the facility button. Therefore, the laptop computer would not enter standby.

I checked out exercise monitor, nothing prevents sleep there. pmset exhibits the identical, i.e. nothing prevents sleep. I’ve tried to reset SMC and PRAM, nevertheless it did not assist.

Bluetooth, Wi-Fi and Airdrop have been disabled, once I closed the lid.

I can not determine, what else I can do to resolve the issue.
