How do I limit battery charging to 80% on Ubuntu?

Question

I'm using a Dell XPS 13 7390 and am wondering if this is possible. I can do this in Windows but the Dell power management app doesn't seem to be available for Ubuntu.

Answer 1

You have to use Dell Command Configure.

After installing run

sudo cctk --PrimaryBattChargeCfg=Custom:<low>-<high>

e.g.: sudo cctk --PrimaryBattChargeCfg=Custom:50-80

and adapt the low/high thresholds.

The same settings are available in the BIOS.
