Does the Nintendo Switch OLED overcharge?

No, the Nintendo Switch OLED doesn't overcharge because it has built-in circuitry that automatically stops charging once the battery reaches 100%, even if left in the dock or plugged in, preventing damage; it's safe for overnight charging, though keeping it docked constantly can generate heat, which slightly impacts long-term battery health.
