following instruction on: Framework Laptop - ArchWiki and verified by the first screenshot, it’s already in s3 deep suspend yet the battery still drained by a lot. Any suggestion?
Hibernate. You can setup suspend-then-hibernate in systemd, which is what I’ve done (if you use Gnome or KDE, they also probably have a similar setting). Within the first hour, if I open up my laptop, it resumes from deep sleep. After that, it goes into hibernation.

I’m using btrfs and LUKS so there would some major hoops for me:

I use LUKS and LVM and I have a permanent encrypted swap partition. Here’s the output of lsblk --fs:

I don’t know if BTRFS complicates things, though.
I managed to get it working by following arch wiki (helpful as always). Essentially it’s a swapfile and the fstab simply contains:
/path/to/swapfile none swap defaults 0 0
the kernel parameter is a bit annoying, needs btrfs_map_physical for resume_offset calculation, just follow arch wiki
