When an over-the-air iOS update starts downloading on your iPhone or iPad, you can monitor its progress in the Settings app via General -> Software Update.
The lack of a cancel option on this screen seems to imply that there’s no way to prevent a software update from downloading once it’s started, but don’t be fooled. You can stop the update process in its tracks at any time and even delete the downloaded data from your device to free up space. Here’s how.
First, you’ll want to pause the download by temporarily disconnecting your iPhone or iPad from your Wi-Fi network. The easiest way to do this is by enabling Airplane mode: swipe down from the upper right of your device’s screen (on iPhone 8 or earlier, swipe up from the bottom of the screen) and tap the Airplane button in the top left of the Control Center grid.
Now that’s done, follow these steps.
Launch the Settings app on your iPhone or iPad.
Tap iPhone Storage.
Locate and tap the iOS software update in the app list.
Tap Delete Update and confirm the action by tapping it again in the pop-up pane.
How to Turn off Automatic Updates
If the OTA software update started downloading automatically without your consent and you’d like to prevent this behavior in future, you need to disable the default automatic downloads setting on your device. To do so, simply launch the Settings app, tap Software Update, and toggle off the switch next to Automatic Updates.
