  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.

        This is incorrect.

    Interesting. I have always felt that the Steam deck loses quite a bit of battery percentage during sleep. I agree that it would be a fantastic quality of life update to enable to shut down or enter some form of lower power consumption hibernation state after a period of time at a certain battery level.

  I personally wouldn’t want that, at least not if it’s on a game.

    Hibernate would be great as it’s a slightly longer restore, but should work the same (if you are willing g to sacrifice the disk space)

    Being able to pick up the deck and know it will have battery left would be really nice. It drains pretty fast in sleep mode.

    It can’t dump a save state to disk? I guess that would be difficult on a normal OS.

      That’s basically what hibernate is. Shouldn’t be hard to offer as an option.

      The difficult bit is having it wake from sleep to hibernate itself. I suspect that would require hardware.

        Almost no modern device does a traditional S1-3 sleep. They all do S0 standby/modern standby in windows 8+ parlance. The system is on the entire time. So “waking up” to go to hibernate is basically the same as doing it from a normal on state.
