The Samsung Galaxy S25 and S25 Ultra come with an automatic sleep mode designed to save battery by dimming or turning off the screen after a period of inactivity. While this is helpful for extending battery life, it can interrupt tasks like reading, watching videos, or using navigation apps.
Disabling automatic sleep mode allows your phone screen to stay on longer or remain active when needed. This is especially useful during presentations, gaming sessions, or hands-free use, where you don’t want your screen turning off unexpectedly.
In this guide, you’ll learn how to disable or manage automatic sleep mode on the Samsung Galaxy S25 and S25 Ultra. Follow the steps to keep your screen awake as long as you need, whether temporarily or permanently.
