Can my iPhone 6 have iOS 16 update?

No it cannot.

An iPhone 6/6 plus can't be updated beyond 12.5.7, it doesn't have the hardware required to run anything higher.

If you need a higher iOS version, you will have to purchase a newer phone.

• If you have an iPhone 5S or 6/6plus, the highest you can update to is 12.5.7

• If you have an iPhone 6S through 7, or SE 1st generation, you can update to 15.8.2

• If you have an iPhone 8 or X, you can update to 16.7.7

• If you have an iPhone SE (2nd generation or later), or XR through 15, you can update to 17.5.1

You can update your iPhone 6 as far as the latest release of iOS 12 – but no further. Chances are, you're already there, in which case you're not going to see any further updates on the Software Update screen.

The iPhone 6 will never run iOS 13, 14, 15, 16, or 17.

Read the thread, where it's been answered that NO, iPhone CANNOT be updated to iOS 16. It can't be updated to iOS 13, 14, or 15 either. If you need anything higher than iOS 12.5.8, then you'll need to buy a newer, more modern iPhone and retire your 10 year old phone.

Impossible. iPhone 6 cannot update to iOS 16.

The final update for the iPhone 6 was iOS 12.5.7

This has already been answered in this thread multiple times, but to repeat......

No, you would need an iPhone 8 to run iOS 16.
