9. Customize the Crap Out of Control Center
Swiping up from the bottom of the screen on an iPhone has always brought up Control Center, but in the past it was limited to just the controls Apple wanted to provide. While that’s still true for many of the controls, like the network connections, audio playback, screen mirroring, brightness, and volume, to name a few, you can now customize all the rest. Never use the flashlight or calculators? Dump those buttons.
The customization is much more about the cool controls you can add when you go to Settings > Control Center > Customize Controls, including: Low Power, Text Size, Wallet, Stop Watch, Voice Memos, Do Not Disturb While Driving, Notes, and many more. Your options may change depending on the type of iPhone you have, since some have other features.
Tap the green plus button to add something to Control Center; select the red minus button to delete. To organize the order of the buttons, drag them using the menu on the right.
In Control Center, use a long-press to access an adjuster that controls the intensity of screen brightness, volume, and flashlight.
