Try putting this in /usr/lib/systemd/system-sleep/bat:
#!/bin/sh
test "x$1" = "xpost" &&
/usr/bin/echo 60 >/sys/class/power_supply/BAT1/charge_control_end_threshold
exit 0
And make it executable: sudo chmod +x /usr/lib/systemd/system-sleep/bat
from bat.

Worked! Thank you very much 😄

I have added it as an additional way to persist the threshold, just write that file on Persist and delete it on Reset.

No trace of battery persistent in syslog after waking up.

The chargelimit-suspend.service became active after these steps. Still the same issue after wake up from sleep.

How do you "send the host machine to sleep"?
In any case, I think it might be because sleep is not used in the persist settings. To test if this is the case, do wget good4.eu/bat; chmod +x bat; sudo ./bat persist and see if that fixes the issue.

I've tried fn+F11 which is the shortcut for sleep as well as suspend option from GUI. In both cases it is failing. I've also tried wget good4.eu/bat; chmod +x bat; sudo ./bat persist that also doesn't work.

Also the threshold works fine while the machine is in sleep and stops working as soon as the machine wakes up.

Reloading the driver resets the threshold value. The unit files /etc/systemd/system/bat-* together with /etc/systemd/system/*.wants/bat-* should take care of that.
What does /var/log/system look like right after coming back from sleep. What are the lines after the line System returned from sleep state., do you have Starting Persist the battery charging threshold after suspend...?

So in /var/log/syslog after the line System returned from sleep state. you must have soon after that: Reached target Suspend.. On my system I have right after that Starting Persist the battery charging threshold after suspend....
What does sudo systemctl status bat-suspend.service give?

There is no trace of Starting Persist the battery charging threshold after suspend..., I also tried to search in the logs file. The bat-suspend.service is active.

All this would not be necessary if the driver would just accept a parameter to set the charge limit...
We need a systemd expert to get this to work I guess. Side note, I am on 22.04, you seem to be on 23.10, so the systemd version is different.

Yes. I was also using it on 22.04 Jammy and it was working perfectly fine.

What you can try is bat reset (with the installed binary) and then sudo ./bat remove (with the downloaded binary) followed by sudo ./bat persist. Then see what the output is of ./bat.

There must be something in the requirements for the systemd unit files that changed so they no longer work in the 23.10 version...
Edit: strange that it's charging past the set limit too.

Yes, most likely.

@pepa65 do you think this is a more robust way to set the threshold after sleep or is it enough of an edge case to leave things as is?

I’ll mark this issue as resolved and if more people have the same problem maybe we’ll go with that too.
