How to update iPhone 6 to iOS 13

There are no iOS 13 updates and no hardware upgrades available for an iPhone 6.

An iPhone 6 is forever limited to iOS 12.

For current iOS, you will need to replace it with an iPhone 8 or newer.

iPhone 8 is the oldest iPhone model with support for the current iOS version; iOS 16.

An iPhone 6s and 6s Plus can be upgraded to iOS 13, but an iPhone 6 cannot.

You cannot. An iPhone 6 cannot update beyond iOS 12.5.6. Its too old and lacks the hardware to run anything newer.
