how to update ios

iPhone 6 is a nearly 9 year old iphone, which is now obsolete, and cannot run the lates iOS version (iOS 16, if that's what you're looking for). It lacks the hardware required. The highest version an iPhone 6 can run is iOS 12.5.6.

If you need the newer iOS versions, then it's time to retire you old iPhone and buy a newer, more modern iPhone.

Updating an iPhone:

See my User Tip:  Update your iPhone Using a Computer - User Tip

Update Third-Party Apps, aswell.

Curious, but how is your advice to use one's computer going to help this user get the latest iOS on iPhone 6? iPhone 6 is not capable of running iOS 16, computer or not.
