It's hard to believe that we've spent the last decade jumping over to the Settings app every time we want to join a Wi-Fi network or connect to a Bluetooth device.
But iOS 13 changes all that. Finally, we can we do those things right from Control Center, without leaving the app we're using.
It's really easy, here's how it works.
First, open Control Center. It's a swipe down from the upper-right corner on iPhones that have no home button, and a swipe up from the bottom on iPhones that do have a home button.
Then tap and hold on the connection area to expand it, or press hard if your device has 3D touch.
Tapping on the Wi-Fi or Bluetooth buttons will just turn them off or on, just as they always have.
But in iOS 13, you can tap and hold, or press hard with 3D touch, on the Wi-Fi connection icon to bring up a list of available Wi-Fi networks. Then just pick the one you want to connect to.
Do the same with Bluetooth button to see paired Bluetooth devices and connect to one.
