Do Not Disturb Enhancements
Do Not Disturb already lets you tune out notifications, but those capabilities are expanding in a big way. Namely, a new Do Not Disturb During Bedtime mode will help you get a better sleep by blocking all of the notifications you receive in the middle of the night from showing up on your lock screen and holding them for you until when you’re ready to see them in the morning. You can control the times and locations that will enable or disable Do Not Disturb from Control Center.
Every new version of iOS comes with system-wide speed and stability improvements and iOS 12 has some notable ones. This time, Apple focused on some of the simplest things you do dozens of times every single day. Some highlights: up to 70% faster swipe to camera, up to 50% faster keyboard display, and up to 2x fast app launch when your iPhone is under a heavy workload. Best of all, you'll see these performance boosts even if you have an old iPhone -- Apple said they're supported all the way back to the iPhone 5s from 2013.
