How long can the deck be off before needing Storage Mode?

Valve just states this:
If you won't be using your Steam Deck for a while and would like to place it back into storage mode to increase long term battery health, you can use the following steps to do so...

How long is 'a while' ?

It’s just a guess but I would say more than 2 weeks as the battery would probably drain in that amount of time if left on sleep mode

I normally shut it down when i'm done with it, so it would hold a charge longer but still with a slight discharge due to its internal clock running and whatever else.
I was just curious how long it would take for battery degradation to start happening overall with the Deck without that mode active to preserve the battery health.
I'm struggling to find anything on it anywhere.

Does this apply if you leave it plugged in ?

I wouldn’t recommend keeping it plugged it as it will also effect battery life. I know most electronics have a safety feature where it stops charging after charge, but there’s still gotta be some battery degeneration if left on the charger way longer than normal.

Only if you can set the maximum charge to 60 or 80% like a laptop. Batteries loses health faster at both extremes. Only charge any device to full charge if you are planning to use it very soon. Otherwise I will charge my devices to 80%. Some phones will learn your routine and delay charging to 100% overnight until the time you get up and ready to use the phone.

When I leave my Deck off charge (un-used and off), I see it drop about 10-15% of charge over about 8 hours. With that, I wouldn't leave it off charge and off without storage mode longer than a week.

No

Leaving it on charge is actually better if it's not in storage mode. Even though the Deck will maintain a certain level of charge, it will do so using a trickle type charge which is very low impact. When you let the Deck drop to lower percentages then start charging, it goes into a fast charge mode which actually creates heat and puts more stress on a battery.

That being said, the safeguards built into electronics today are designed and built by engineers that spend way more time testing and analyzing than us customers on the interweb. It's not a useful way to spend our time trying to outthink the engineers at their own jobs.

Oh wow that short? I was expecting 3 weeks or so and thought even if the battery died completely it would be okay for a bit. I guess not. Blimey, i'm glad i asked. Thanks Mahjik thats super helpful.
