After a long time of users asking, Valve has actually added an official Battery Charge Limit setting in the latest Steam Deck Beta update so you no longer need to use third-party tools.
The problem is that the Steam Deck APU doesn’t support amd_p_state and you need to rely on auto_cpufreq. This explains why the power consumption in sleep is so high.

It’s a custom chip though isn’t it? Seems a strange choice
I think the amd_p_state is not available on any Zen 2.
