How do i update my iphone to the latest version of ios

Hello,

There are different ways to ensure the highest iOS that your device will support is installed on your device.

This support article has instructions about updating an iPhone or iPad wirelessly --> Update your iPhone or iPad - Apple Support Read the article for recommended criteria for being able to use wireless updating.

You can also use Mac and PC computers to update system software --> Update iOS on iPhone - Apple Support

When updating, your device will update to the highest version currently available that it will support, or it will just say it is up to date (and can't go any higher) and won't install anything. If you want to run a higher system version than your current device is capable of running, you need to buy a newer device.

An iPhone 8 or later will directly update to the latest iOS, 16.4.1

But, iPhone 7 Plus cannot run iOS 16 or iOS 17, if that is what you are asking about. iOS 15.8.2 is the end of the update road for the iPhone 7 Plus.
