It’s locked up once since I’ve made the change from deep to s2idle. It goes into hybrid sleep at least three or four times each day, and it was previously locking up every two or three days.
It appears that the change has helped with the lockups.

On 11th gen laptop, resuming from deep sleep is not faster than resuming from hibernation. I prefer s2idle and sleep-then-hibernate for the best experience. I set the system to sleep of 60mins then switch to hibernation, which costs only 2% battery drain at most.

I’m set up the same way and can verify the same behavior. I see about 2% drain under hibernation.
And haven’t had a mouse lockup during resume in in a few months, so I expect something fixed that one.

I decided to clone my ssd to an Intel 660p and now deep sleep works properly. There is definitely some kind of problem with Sabrent Rocket ssds and Linux.

Fedora 37, kernel 6.1.5-200, battery drained from 98% to 75% (23% diff) for 12h of sleep (deep sleep enabled).
No SSD or other hardware issues

How long was this in suspend for by chance?

For 12 hours, sharp

So 12 hours suspended (deep sleep, not hibernate), that sounds about right. We’re measuring power drain to improve upon it (expansion cards, etc). However, there will be some power drain as it’s not in a proper hibernation state.

I wonder if you would have less battery drain with s2idle sleep.
I’ve used deep sleep in the past, but since a few months ago, with the 6.x kernel series, I have less battery drain, and faster resume latency, when using s2idle sleep instead of deep sleep.
To use s2idle until the next reboot (as this doesn’t change the kernel command line on disk), write s2idle to /sys/power/mem_sleep. This should work on most distros:
sudo su -c "echo s2idle > /sys/power/mem_sleep"
I should mention that I have a 12th gen Intel Core i7-1260P, if there any differences in terms of sleep with the 11th generation. Confirmed on Linux kernel versions 6.0.6-arch1-1 and 6.1.5-arch2-1.

Let’s keep this on one thread for tracking please.

Thank you. However, your use of ‘a’ and ‘b’, and your omission of code formatting, makes your post a little hard to read. So, to aid clarity, let me list (/reformulate) the code and settings at issue - thusly.
The string to be added to one’s boot string is mem_sleep_default=deep.
The command to update-grub is: sudo update-grub.
(Incidentally, one can use the program grub-customizer for this stuff. One will need to find a way to install that program. On Ubuntu 24, and distros based on Ubuntu 24, there is a PPA advertised on the 'net.)
The verification command is cat /sys/power/mem_sleep.
Also/but: on my AMD Framework-13, the verification fails, i.e., deep sleep appears to be unavailable (even after telling the ‘tlp’ program to use deep sleep). EDIT: ah, this thread says deep sleep is not supported on Framework’s AMD laptops.
