For me it depends on what I’m doing. If I gaming for any length of time I keep it plugged in. The reason is I have no battery life indicator to go by. I don’t want my computer shutting down in the middle of anything. If I’m working from home remotely or game designing or writing tech guides, I wait till i’m around 15 percent battery life left then plug in till back to 100%, either if I’m still on or when I have logged off.
