Is it normal for my Nintendo Switch, to get warm when playing a game on handheld mode

Yes, it is normal for a Nintendo Switch to get warm when playing games in handheld mode. This is due to the hardware working to run the games, which can generate heat. The degree of warmth can vary based on factors like the intensity of the game, the duration of play, and the environmental conditions. However, if you notice that your console is becoming excessively hot to the touch, or if it shuts down due to overheating, it could indicate a problem. In that case, it’s advisable to give it a break, ensure proper ventilation, and check for any software updates. If the problem persists, consider contacting Nintendo support for assistance.
