In case you still want some of the functionality, without the nice GUI, here's some equivalent commands.
These should all be run as superuser, i.e. run `sudo su` and then run these commands in that.
NOTE: sysfs entries are subject to change with kernel updates. For example, hwmon indices may be incorrect if they were written for an older kernel. NGnius does not always keep this up to date with the latest numbers.

# Set battery charge mode
There exists a binary which may or may not be executable (depending on which SteamOS version) which can be used to set this and other things. [More details in the issue](https://github.com/NGnius/PowerTools/issues/50).
There exists a binary which may or may not be executable (depending on which SteamOS version) which can be used to set this and other things. [More details in the issue](https://git.ngni.us/NG-SD-Plugins/PowerTools/issues/50). Unfortunately recent SteamOS updates have removed that part of the binary's functionality.
Refer to [util.rs](https://github.com/NGnius/PowerTools/blob/main/backend/src/settings/steam_deck/util.rs) for how the firmware interface works.

# Set battery charge limit
This also used to require the binary in [this issue](https://git.ngni.us/NG-SD-Plugins/PowerTools/issues/50). Luckily this is replaced by a sysfs interface in SteamOS 3.5: `/sys/class/hwmon/hwmon4/max_battery_charge_level`. The number is the percent charge; 100 is full, 0 is empty.
