Better Notifications
The notification system is one of the coolest things in iOS 15 that iOS 14 just can’t compete with. Now notifications will have a nicer, more detailed preview that can show you the photo of your contact or a better icon of the app that notifies you. With iOS 15, you now have the option to use a notification summary that will show you a list of your notifications at any given time of the day you want. That way, you can focus on your urgent notifications and leave everything else for when it’s late in the evening or early in the morning.
