To update over the air from the phone all of these requirements must be met:
- You need at least 6 GB of free storage
- You must be connected to a Wi-Fi network (and not a personal hotspot) unless it is an iPhone 12 or 13 series with an active 5G network connection
- The phone must be charged to at least 50%, and preferably plugged in so it stays above 50% during the update
- The phone must not be in Low Power Mode
- The phone must not be connected through VPN, and it may be necessary to delete any VPN apps and VPN profiles
- The phone cannot be in Airplane mode
- You cannot still have a beta version installed on the phone
- You cannot have a previous version that was downloaded, but not installed - go to Settings/General/iPhone Storage to look; if you find an iOS installer, delete it
If you can't meet all of them you can still update using your computer.
