Advanced Battery Settings not Respected, System Continues Using Default

I have my low battery percentage set at 30%, and critical at 20%. These settings don’t appear to save between different sessions, as it’d often drop to 3% (the default) before warning me that the battery is at critical, bypassing the low battery warning entirely as per default. Due to such cycling and a few accidents when first purchasing this laptop, my battery is at 81% after less than a year of use, which is quite concerning.

From your previous posts i gathered your laptop has a BIOS from 2020, and there is an update released in June 2021 for it

Also i recommend following this Dell XPS 17 (9700) - ArchWiki and the power management part.
