This question probably applies to most any device with a rechargeable battery, but here goes:
We all know batteries degrade over time. Some types of batteries last longer if you primarily do full discharge cycles, others are better if you keep them topped up continuously. What is best for the Steam Deck's battery? Mostly interested in what to do between playing sessions. If the battery is already fully charged, should I
- Turn the deck off and unplug
- Put to sleep and unplug
- Turn off and leave plugged in
- Put to sleep and leave plugged in
Obviously (4) is the most convenient, but that causes periodic recharging to happen, which can be observed by the charging light coming on occasionally. Does this activity measurably degrade the battery over time?
