If you want to stop the Switch from forcing itself into a sleep mode, then you need to change a setting called “Auto-Sleep.” This feature monitors the amount of time since you last pressed a button or interacted with the screen, and will put the Switch into sleep mode to conserve battery power. By default the Nintendo Switch has some active settings that help to extend the amount of life you get from one battery charge, therefore helping you prolong the amount of time that you can use the Switch. Like many other electronic devices with batteries that can allow you to use them without tethering yourself to a power outlet, you are able to adjust some of the settings that affect how that battery life is used. But if you want the screen to stay on until you shut it off manually, our tutorial below will show you how to stop the Nintendo Switch from going to sleep by changing the setting for this sleep timer.
One of the reasons that this is possible is because the Switch will turn itself off when you haven’t used it for a while. The battery life on the Nintendo Switch is pretty good, and it’s likely that you can play it for several hours before you need to connect it to a charger.
