How do you turn off sleep mode on your you phone?

To turn off sleep mode on your phone, go to the "Settings" app. Look for "Display" or "Screen" settings, where you'll find options for "Sleep" or "Screen timeout." Set the duration to a longer time or select "Never" to disable automatic sleep mode. On some devices, you can also adjust these settings in the quick settings menu by swiping down from the top of the screen.
