pmset -g

From man page: hibernatemode = 25 is only settable via pmset. The system will store a copy of memory to persistent storage (the disk), and will remove power to memory. The system will restore from disk image. If you want "hibernation" - slower sleeps, slower wakes, and better battery life, you should use this setting.

reference: https://apple.stackexchange.com/questions/113954/difference-between-autopoweroff-and-standby-in-pmset

standby setting

set standby to 12h after sleep

sudo pmset -a standbydelayhigh 43200
sudo pmset -a standbydelaylow 7200

set autopoweroff to 24h after sleep

sudo pmset -a autopoweroffdelay 86400

After sleeping for seconds, the system will write a hibernation image and go into a lower power chipset sleep.
