So many times I forget to plug the deck or someone uses the charging cable for something else and I come back to play the next weekend and the deck is at 0%. Why doesn’t the deck have a deep sleep or hibernate mode on by default like my laptop or iPad?

Linux has typically been buggy when it comes to hibernation. I wouldn't bother, it's not worth the risk in my opinion.

It’s not really a risk- it stays plugged in all the time…except on the rare occasion when it doesn’t. ;-)

I’m surprised there isn’t some kind of fail-safe that starts a graceful shutdown at 10-20% if it’s been in sleep for >x hours. Taking a LiPo to 0% is terrible for the pack; most devices have some sort of fail safe against this kind of battery stress.

Isn't keeping it plugged in all the time really bad for the battery? It should stay between 30 and 80% iirc.

Iirc the SD does discharge from full battery a bit when plugged in for a while to preserve battery health.

[–] [email protected] 3 points 1 year ago

It lets the battery discharge to 90% while plugged in. If you’re not using it for a few days you should still unplug.

[–] [email protected] 1 points 1 year ago (1 children)

It will still keep it above 90% all the time which is bad according to most comments I just found by googling about it, it's just the nature of lithium batteries. Steam deck allegedly has a feature to use direct power from outlet if in use while charging and if at max, but it still keeps battery at high %.

Most of that is really old knowledge from before the days of sophisticated charge controllers.

Maintaining a high SoC is still very damaging to battery life.

[–] [email protected] 1 points 1 year ago (1 children)

Which is why the charge controller does not do it. It will drop to a sustainable voltage when it detects longer wired connection after being charged and adjusts the "percentage" it shows you accordingly so you still see a 100 to 0.

Do you have anything to back that up with or are you speaking from personal incredulity? What you said certainly does not apply to e.g. contemporary smartphones.

[–] [email protected] 1 points 1 year ago

Contemporary smartphones tend to push things a bit harder to offer the "best" performance in the first few weeks. Though I have to say comparing today's newest phones with phones from 2015, battery management has gotten a lot softer.
