I want to up date my iPhone

Please do.

Update your iPhone or iPad - Apple Support

Make sure that your iPhone is setup to meet the following requirements before you attempt to update the iOS version over a Wi-Fi Network. Open Settings ➡️ General ➡️ Software Update: If there is an update available for your iPhone then it will be listed here. Follow the on-screen instructions to download and update your iPhone. 

• Your iPhone must have a fast Wi-Fi connection; you cannot update over cellular data or a cellular hotspot
• Ensure that you do not have a beta profile installed from a previous version
• The iPhone can not be in Low Power mode
• The battery state of charge must be above 50%
• Your iPhone must have at least 8GB or more free storage space
• Your iPhone cannot be connected through VPN
• You should leave the phone plugged in until it finishes updating, both to assure that it remains above 50% and to keep Wi-Fi enabled (Wi-Fi turns off when the phone sleeps if not connected to power).

Hello Buenolorge59!

In addition to sberman’s link, I’d like to provide this one: If your iPhone or iPad won't update - Apple Support.

I hope this is helpful! Good Luck!

Use a computer or the Software Update function in Settings. If you encounter a specific issue, describe it in this thread.

You shall find all of our answers helpful in achieving this goal of yours.

If you have an iPhone 12 Pro Max, as your profile suggests, the article I provided and methods others explained will allow you to update.

You can under settings. Once settings is open click general, and then software update, it’s the section option from the menu.

good luck (:
