How can I update my iOS software without using computer?

is it possible to update an iPhone 7 to the latest version using only Wi-Fi? If so, what are the steps?

iPhone 7 cannot update to iOS 16.....the latest version.....if that is what you are asking.

The most up to date version of iOS for the iPhone 7 is iOS 15.7.2

Make sure that you have a good Wi-Fi connection

Tap Settings

Tap General

Tap Software Update

If an update is available, it will appear

Or just go to Update your iPhone or iPad - Apple Support.

Go to Settings

Next to General

Next to Software Update.

There you can see if is any update available....

1. Go to Settings.
2. If an update is available, then there will be a red number like you see in the Mail app when you have new mail. Select the option that has the red number.
3. Follow the instructions to install the latest software.

Battery cannot be on Low Power Mode

Battery needs to be at 50-60% or more

You do need a good cellular connection as well

Yes, the version 15.7.2 is what I’m trying to update. I have good WiFi but it won’t verify the update without internet connection. It says it is downloaded but won’t install because it’s no longer connected to internet - except it is.
