Further info:

Suddenly a popup will show critical battery warning 0% → it will jump to like 97% or whatever the real percentage is then. Annoyingly it will also go to sleep mode a few seconds later and I have to wake it up and login again.

This seems to mostly occur shortly after disconnecting my charger?

The problem is the battery. Check that the connector it fitting well and no pins are bent.
If that does not help, maybe there is a bug in the battery bms.
The reason it goes to sleep is because battery below 4% causes the EC to shut the laptop down before it damages the battery. Now in your case the 0% is a false reading, but the EC firmware is not detecting it as false.

Hey, I saw this exactly once a few weeks ago, using Gentoo. I think I was still on 6.16 kernel.

No idea what happened.

If you use KDE you can check the battery’s voltage in Energy — Info Center, in addition to terminal commandupower

If the voltage is around 17V the battery is about 97%. if the battery is only 13~14V the battery is at about 4%
