Remove pending iOS updates

iOS automatically downloads a new software update over Wi-Fi and prompts you to install it. Should you decide to skip installing a downloaded software update, you can regain anywhere from a few hundred megabytes to a few gigabytes of storage simply by deleting the pending iOS installer.

Delete software download

Go to Settings → General → iPhone Storage, Tap the software download in the list and select Delete Update.
