"Screen off" means to turn off the display (screen) of an electronic device, such as a computer or a phone, to conserve battery or to keep it from being damaged. You can use the expression in conversations with friends or colleagues when you are explaining that you need to stop using your device temporarily or when you are giving instructions on how to use a device properly. For example, "I'm going to screen off my phone so it doesn't distract me during the meeting" or "Make sure to screen off your laptop after you're done using it to save the battery."
