I use Ubuntu btw. Poweroff could use more write cycles on the SSD because it has to read everything at startup, but suspend has to keep supplying power to the RAM

    Maybe there’s not a huge difference, but the power usage of suspending is definitely lower, since only the RAM is getting power. CPU and disks have some idle power consumption, and you can have some background processes that wouldn’t be executed while suspended.

      Depends on what you run on your system, but when my system idles my cpu is at literal 0%, ram at 600mb and disk usage is 0% (nvme), which ends up my total power usage to about 3W on idle or something like.

      It’s a laptop so doesn’t use a lot.

      This assumes you have a machine which supports proper S3 sleep, which newer devices increasingly do not :(

      A lot of modern laptops only support S0 “modern standby”, which basically means the kernel puts all processes including itself on pause, but the CPU and all other components are still powered despite being idle.
