I’ve downloaded iOS 15.5 for my iPhone 6s but it’s not installing. Why?

Can someone help me fix this?

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)
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.
