SD battery life expectancy ?

[karmazyn1]

I watched few teardowns and apparently replacing battery is most difficult. I wonder how long will battery last? 2 years with 10% degradation per year? Battery will have to be recharged every day, sometimes twice a day.

Sorry, really a new thread reg. battery life? There are a couple of them, all active.

Depends on how often you use it

Oh my. I did not know.

After 4 and a half months my battery degradation is less than half a percent according to the stats available in the desktop mode. That is with a minimum of one charge cycle per day but 2 most days. That is also playing with it docked for at least a few sessions per week. Now I did have a few weeks back where it was showing that my Deck was only 88% of original capacity but after letting it drain to below 5% and powering it off then charging it fully back up it went back up to 100% of original capacity but if I do the math myself between the two numbers it's more 99.7% of original capacity.

Long story short the battery management systems in place by Valve do a really go job so far so I wouldn't worry too much about it and just enjoy your Deck.

* How long will the battery last?
** Well, this depends on many factors. Do you use your Deck daily or does it sit for spells? Is it always plugged in?
* Is your battery giving you trouble or are you just fretting over things? I mean you're gonna get different life running some phone game like "Wayward Souls" vs. a "real" game like Elden Ring...
* Probably replacing the LION cell is a solder job but I haven't looked. Most likely, in the near future, you'll be able to get a bigger cell.

So... best information w.r.t. randomly selected Lithium Polymer cells is that they expect 1000 to 2000 charge cycles. So your worst case scenario should be 16 months at two charges per day. Your optimistic view would be 66 months (5.5 years) at one charge per day.

A fairly extreme case of YMMV. Even the "battery health" bit is a bit contrived. They're sampling some statistic that may indicate wear ... they are not measuring wear. For all you know, hard resetting the system may reset the data and give overly optimistic (or overly pessimistic) estimations.

My first question would be: do we know what the battery health is querying? Is it part of the open source part of the deck? Certainly we could be more confident about it's output if we knew what it was doing.

do we know what the battery health is querying?

available voltage?

The truth is that you will need to replace it at least once. And then you will be able to use a lot less glue, making subsequent replacements a breeze.
