Extending Switch Pro Controller battery life lets you play longer without recharging. The Pro Controller typically lasts 40 hours on a single charge—here’s how to maximize it. Lower the controller’s brightness: go to 'System Settings' > 'Controllers and Sensors' > 'Pro Controller Wired Communication' and adjust the LED brightness to the lowest setting. Disable vibration: turn off vibration in-game or via 'System Settings' > 'Controllers and Sensors' > 'Vibration Intensity' > 'Off'—vibration drains battery quickly. Disconnect the controller when not in use: press the SYNC button to turn it off, or it will auto-turn off after 10 minutes of inactivity. Use a high-quality USB-C cable for charging—avoid cheap cables that charge slowly. Store the controller in a cool, dry place—extreme temperatures reduce battery lifespan. If the battery life drops below 20 hours, replace it with a compatible Pro Controller battery kit, or contact Nintendo Support for repair.
