Context: I’m a mostly causal gamer. I use the deck for a max of three hours at a time, maybe ten hours a week, owned mine since last august and it’s doing fine, the battery is at 97% from what I can tell.

April '22 deck, pretty much daily use over a year and a half by now, still 100% battery health.

Although I’ve only completely drained the deck of battery a handful of times - either to replace the SSD or just fucking around. Most of the time it hits around 60-40% when I’m out and about and then I top it off. Likely to be a big factor in keeping it in good condition as full cycles are generally bad for current battery tech in anything.

Mine is still claiming 100% battery health, and it certainly feels like the battery life is about the same as when it was new. I got mine early March 2022.
