Hello. I just want to ask, I already tried search many resources, but I still can't find a way to reduce battery drain while sleep on Ubuntu on Dell laptop.

I seen that it use S0ix, the new standard that many manufacturer use but when sleep it drains a lot battery, in just 6 hours the battery gone 0.

Any help is appreciated. This is company laptop and it requires me use ubuntu (I don't like it but I don't have options to changes OS/distro).

Thanks

      Nah, it's a systemd setting. You need to edit /etc/systemd/logind.conf and change HandleLidSwitch= to HandleLidSwitch=suspend-then-hibernate, and the create or edit /etc/systemd/sleep.conf to change the timeout value:

      [Sleep]
HibernateDelaySec=900

      With the above, the system will automatically hibernate after 15 minutes of sleep.

      Note that if you're using a full-fledged DE or a third-party power profile manager, you may need to disable any lid-close actions in there (if it doesn't have the suspend-then-hibernate option) so that systemd can handle it properly.
