Systemctl suspend drain too much battery on sleep

view story

https://bbs.archlinux.org – Hello everybody,I moved to systemd few times ago with a very good result in term of cleaning//system speed and so on, but i noticed that the suspend function from systemd drain a lot of power during sleep.I can't debug right now (no more pm-utils) maybe is just a feeling (also because ai swhitched from a macbook to a samsung ultrabook in almost same period of the systemd swhitch) but i notice a heavy battery drain on sleep. I can say with my macbook the battery was lasting days with less 10% battery on sleep while with my new laptop it can't survive a night on 5/10% battery suspentio (HowTos)
