Bypass charge limit once?

Framework Laptop 13

1

Most of the time my FW13 is connected to a charger all day, but some days i use it on battery. I’d like to set the charging limit to 70% to preserve battery but before i go out set it to 90-100% so i have the extra battery life. Is there a way to do that without going to uefi each time?

I think what I’m looking for is a script which says “charge to full but only until charger is disconnected”, and when charger is reconnected it only charges to whatever is set in UEFI.

tlp fullcharge does exactly that and is apparently going to work on the framework soon™.

BIOS 3.16 (AMD 7040, other recent BIOS versions for other platforms) is exposing the EC, do you happen to know if there is some ongoing work in the kernel to surface this in the sysfs API? Or is the cros_charge-control module’s probe_with_fwk_charge_control parameter the only “missing link” for this functionality to appear by default?
