11 Toggle Wireless On or Off
Use 3D Touch on the Settings icon and you’ll see a contextual menu with quick links to some of the most popular wireless features: Cellular Data, Wi-Fi, and Bluetooth. You’ll also see a battery link with a visualization of your current charge level.
Tap any of these to quickly make changes like turning off Bluetooth, connecting to a new Wi-Fi network, checking your cellular usage, toggling low power mode, or seeing your battery usage. It’s not groundbreaking, but it makes accessing some settings a little quicker (if you remember it’s there).
