I dual boot Win 11 and Ubuntu. I use Win most of the time with hibernate but some 6 hours ago I closed my lid using Ubuntu to find some 28% of the battery drained after 6 hours. So I will look into the Linux sleep tweeks.
I wonder how many people are actually not aware of the sub-par out-of-the-box behavior under Linux because they use their devices differently, so they don’t run into these things - at least not right away.
It’s a bit of a joke, that the community needs to debug this instead of their own QA, but deep sleep is no longer working for me either after the 3.20 update on Ubuntu:
There is s2idle (S0) and there is deep (S3). You can find out what your system is doing via the command:
cat /sys/power/mem_sleep
I expect it to be s2idle in your case and you can try to change it to deep and see if you’re affected as well.
The point here is that S3 is the better mode to use to reduce battery drain as S3 puts most components to sleep compared to S0 - which at least on framework laptops is not nearly as good as stated in other places. Also the reason why you Ubuntu ate 28% of the battery while in suspend.
The best writeup on the battery consumption on framework laptops I have found so far is the following blog. This is for the 12th gen though, but gives you an idea of what kind of skillset you require to dig into the mess that is suspend modes in Linux in general and in combination with Intel CPU in particular. https://anarc.at/hardware/laptop/framework-12th-gen/
Does anyone other than me have an 11th gen system that is on bios 3.20 and works fine with deep sleep and suspend? If you’re not on 3.20 and rely on deep sleep, please don’t dive in to test as you run the risk of losing that functionality. I am trying to understand why my machines work but others don’t. Both of them have the RTC replacement module installed.
I have only tested it on linux, but I will boot up windows (I think I have win 10, not 11 on those machines/the expansion cards for them) and add a post with the outcome.
