What is Update Requested on iPhone

Perhaps, disconnecting and then reconnecting to WiFi will jar the update and allow it to begin. Try putting the phone in Airplane Mode, restart again, wait a minute or so, then tune Airplane Mode off.

Settings>Airplane Mode>On. Restart the phone. Wait a minute, then go to Settings>Airplane Mode>Off.

If that doesn't work, force restart the phone and see if the update starts. On an iPhone 7 or iPhone 7 Plus: Press and hold both the Sleep/Wake and Volume Down buttons for at least ten seconds, until you see the Apple logo. On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo.

If that doesn't work, see if the update downloaded and if so, delete it and start over again. Settings>General>Storage & iCloud Usage>Storage>Manage Storage. Let the list of apps load. Find the Software update. Tap on it and delete it in the next screen. Go back to Settings>General>Software Update and try downloading it again.

Hi

It may help to follow the steps here:

If you are unable to update wirelessly, consider instead updating via iTunes (and vice versa):

Whichever method you choose, be sure to first make a backup of your iPhone (you may wish to choose the option to Encrypt iPhone backup if using iTunes):

Note that Apple advises that you should not force restart your iPhone unless it is unresponsive and cannot be restarted normally.

Also note that, for iTunes to be able to connect with a device running iOS 10 or newer (including updating it), your computer must be running iTunes version 12.5.1 or newer:

Hard Reset (home + power button for >10 sec) solved my problem when trying to update OTA my 6S to 11.1.

This worked for me. There was no indication that this was the problem (i.e., no instructions that I should be plugged in). Restarting didn't work. Finally I decided to try plugging in (I hadn't found this suggestion yet, which is further down on this page). Immediately after I plugged into a power source, I got an update with how many minutes the update would take.

It would've been really nice to have:

a. this suggestion (or requirement) included in the "apple recommended" solution at the top of this page

b. if it's required, to call out that the phone should be plugged in on that screen.

(This was for a new phone. For people that are not used to trouble shooting tech issues on their own, I can picture this being really frustrating.)

Thank you, LeoVieira!

Thank you for the help man, it started to download as soon as I plugged it in.

Try using a VPN service like BetterNet, started downloading as soon as I activated VPN.

It sounds strange but even though my iPad battery was 91% it worked when I plugged it in!

Also note that I have force restarted my iOS devices many times over the years. It has solved many problems for me in past and it has helped with many other users to whom I made the recommendation.

I could just post a link for you, but I thought a detailed explanation made more sense.

If you are having this problem with the ios 11 update, tried everything and did not solve it, try PLUGGING IN THE POWER! Sounds idiot but it will probably work!
