I’ve had my Steam Deck since last June, and noticed the battery would drop from “full” when plugged in to 95% as soon as I unplugged it. I tied the calibration method Valve recommends, but also realized when I check the Battery Health in desktop mode/settings, it’s at 88%…which does seem odd after just one year? Curious to hear how others’ devices are holding up.
I keep mine docked most of the time, but for couch gaming (lately it’s been Dave the Diver) it holds up well enough. I can get about 3-4 hours out of it for that game, but I rarely use spend that much time at once on it.
I’ll go in 1-1.5hr blocks a couple times with breaks in between where I just put it to sleep and do something else for a bit.
