How can I update my phone to iOS 16

Hello wire20,

Thank you for reaching out to Apple Support Communities.

If your device is compatible with iOS 16, you can update using these steps:

Update your iPhone or iPad wirelessly

1. Back up your device using iCloud or your computer.
2. Plug your device into power and connect to the internet with Wi-Fi.
3. Go to Settings > General, then tap Software Update.
4. If you see more than one software update option available, choose the one that you want to install.
5. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don't know your passcode, learn what to do.

If you get an alert when updating wirelessly

Learn what to do if you see an alert message while trying to update your device wirelessly."

If the issue persists, can you provide a few more details on what happens when you attempt to update? Also, which iPhone do you currently have?

Cheers!
