You need an Internet connection to update iOS. The time it takes to download the update varies according to the size of the update and your Internet speed. You can use your device normally while downloading the iOS update, and iOS will notify you when you can install it. To improve the speed of the download, avoid downloading other content and use a Wi-Fi network if you can.
