Can iPhone 6 update to iOS 16?

iPhone 6 can NOT be updated with iOS 16 if that what you are asking.

The iPhone 6 hardware cannot even support iOS 13, 14 or 15.

The best that the iPhone 6 can do is iOS 12.5.6.

Hi sher54 - iOS 16 is not available for the iPhone 6. It works for iPhone 8 and the preceding models

i’m sure it’s only iphone 8 and upwards that can update to ios16
