I noticed my laptop keeps the battery level at 80%, so I asked ChatGPT and learned that my laptop has a way to prolong the lifespan of the battery.
sudo system76-power charge-thresholds
will return the current settings.
You can update the settings like this:
sudo system76-power charge-thresholds 40 60
or use profiles:
sudo system76-power charge-thresholds --profile <profile_name>
Possible values: full_charge, balanced, max_lifespan
