As I mention always whenever this topic comes up, it might be my specific setup but don’t leave it off and plugged into a dock for long periods of time: it seems to discharge the battery and not realizing it’s happened. In my experience as long as you unplug it after shutting it off, there’s no downside.

That’s a good point. I lose about 5% a from the charge limit after a whole day of the Deck being plugged in and mostly on. I suppose doing a weekly power cycle could also work.

There’s also the BIOS setting that turns the Deck on when connected to AC, just in case it does run out of battery and won’t turn on after a power outage.

What I’m describing is really nasty, as you think the battery is let’s say at 95% and you unplug it to be used as ha handheld. It’s updating a few games and you turn around, do something else… then check back on the updates and the Deck is off because it ran out of battery in a couple of minutes. I don’t think it’s good for the battery to be drained that much

That’s really extreme, I’m pretty sure that’s now at all how it should be working.

I don’t leave my deck docked that long, maybe 10 hours at the longest, but I’ve never seen anything like the battery drop you’re describing.
