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

    Why not just set your laptop to automatically hibernate after it’s been in a suspended state for x seconds? That way your system will fully power off after it’s been suspended for a while, which would save even more battery compared to S3. With the speed of NVMe drives, resuming from hibernation only takes a couple of seconds on most modern systems.
