Can’t upgrade iPhone to iOS 13
When trying to update, try to ensure good Wi-Fi and internet connections
QMy iPhone XS running iOS 12.4.1 is set to automatically download updates, but is stuck saying ‘Update Requested’ and won’t download or install iOS 13, even when left charging overnight. How can I update it?
ASometimes iOS devices get no further than ‘requesting’ an update when Apple’s servers are too busy, or when their connection isn’t reliable. Try again when the device has a good Wi-Fi connection to a good internet connection.
You could improve chances of success by shutting your iPhone down, putting it on charge, turning it on again, then waiting a minute or two. After that period, open Settings > General > Software Update, and request any update which is offered. Give it another hour or so on charge with good Wi-Fi and internet, and it should start to download that update.
Access to a Mac or Windows system running iTunes gives you another option. Connect your phone to the computer with iTunes open, and you can download the update to that app and install it from there. This works differently in Catalina: your phone will appear listed in the Finder’s Locations. Select it there, and use the ‘Check for Update’ button. This should offer to download the update then install it. Unfortunately, that’s most reliable with iOS 13.
If none of these work, your phone may need resetting. Ensure it’s well backed up to iCloud and/or a computer before taking it to an appointment at your nearest Apple Store, where they should be able to update it for you.
