You can easily stop your iPhone or iPad screen from turning off automatically or increase the auto-shut off time, in case you are bothered by how quickly your iPhone goes into sleep mode while you are still in the middle of using it.
iPhone Screen Auto-Lock Feature
By default, your iPhone or iPad is set to turn off or go into sleep mode after a certain period of inactivity.
This setting is designed to conserve battery life and it also reduces the chances of unauthorized access to your device, in case you leave it unattended.
As you must have noticed, iPhone is smart enough to automatically disable sleep mode, whenever you are performing activities like watching a movie or a music video.
