Ensure Stable Internet Connection to Fix iPhone Won't Update

If your iPhone can start the update process normally, but the update just cannot finish and stucks on the update interface, then the Internet connection might be too slow or unstable, which would greatly hinder the update. If that is the case, then you can simply try again but keep the following points in mind.

1) Don't turn off your Wi-Fi or leave the coverage of the Wi-Fi network while the update is in progress.

2) If using another device that's sharing the same Wi-Fi network, avoid doing anything that's highly internet intensive, like watching a 1080P video, which will occupy the Internet connection.

3) Be sure you have plenty of battery life left before you start the update, or plug in your phone to charge during the update.
