Tired of notifications that wake up your iPhone or iPad and light up your screen? Using the Do Not Disturb function or changing the notification settings can keep you in the dark. See how.
The quick fix: Enable Do Not Disturb
Apple includes the "Do Not Disturb" feature on any iPhone or iPad. While active, “Do Not Disturb” mutes incoming calls, messages and notifications by default, but this may vary depending on how you set it up.
To quickly activate the Do Not Disturb function, first launch the Control Center on your iPhone or iPad, and then press the Do Not Disturb (which looks like a crescent moon) button.
Alternatively, you can start Settings, press "Do Not Disturb" and press the switch next to "Do Not Disturb" to activate it.
With “Do Not Disturb” enabled and iPhone or iPad locked, incoming messages and alerts will not wake up your device screen. To deactivate the “Do Not Disturb” function, restart the Control Center and press the “Do Not Disturb” button until it is no longer highlighted.
The best solution: Disable notifications on the lock screen
If you do not want to use the “Do Not Disturb” feature to prevent your iPhone or iPad from turning on when you receive notifications, you should look in the device notification settings.
The good news is that Apple lets you turn off lock screen alerts for any app. The bad news is that there is currently no way to edit notification settings in all applications at once, so you will need to turn off lock screen notifications individually for each application that activates your device.
To do this, open Settings on your iPhone or iPad.
In Settings, click "Notifications".
In Notifications, scroll through the list and tap the name of the application you want to prevent your screen from waking up. In this case, we use Messages as an example, but you could do it for Facebook Messenger, Signal, TwitterThe FaceTime or any other application.
In the app's notification settings, tap "Lock Screen" to remove it.
After that, go back to a screen and repeat this process for any other applications you want to mute on the lock screen.
When done, exit Settings and you will no longer see notifications from these applications on the lock screen. As a result, notifications from these apps will no longer wake up your iPhone screen.
