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.
EDIT; thanks for all the feedback! I think there may be a couple different things going on between the battery health as displayed in the dekstop mode/settings and the battery remaining display when I’m in “game” mode. After doing the battery calibration, the battery health still shows as being 88%, which I think is low after only having it for a year, but the calibration did seem to help with the battery remaining being all over the place?
This is normal for the Deck and is done to help extend battery life. Keeping a battery at 100% charge for extended periods accelerates its degredation. The Deck will charge to 100%, and you should see this if you immediately take it off the charger as soon as it finishes charging, but then lets it drain down to about 95% and maintain there if you just leave it plugged in.
