To keep your iPhone screen on longer or indefinitely, you need to adjust the Auto-Lock settings as follows:
- Open the Settings app on your iPhone.
- Tap Display & Brightness.
- Tap Auto-Lock.
- Choose the desired time duration for the screen to stay on. Options range from 30 seconds to 5 minutes, or select Never to keep the screen on indefinitely.
Selecting Never will prevent the screen from turning off automatically, but you will need to manually lock your phone by pressing the side/power button. Keep in mind that keeping the screen on for extended periods will drain your battery faster
. Additional notes:
- If the Never option is grayed out, it might be due to device management policies (e.g., school or work profiles) or if Low Power Mode is enabled. To disable Low Power Mode, go to Settings > Battery and turn off Low Power Mode, then try adjusting Auto-Lock again
- Using Guided Access mode can also keep the screen on while restricting the device to a single app, useful for presentations or specific tasks
In summary, adjusting Auto-Lock to "Never" or a longer time interval is the primary way to keep your iPhone screen on
