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 16.7.10

• If you have an iPhone SE (2nd generation or later), or XR through 15, you can update to 17.6. 1

iPhone XR, iPhone XS, and iPhone SE 2nd gen are the oldest iPhone models that will run the current iOS 17 and the upcoming iOS 18. All are substantially more capable than an iPhone 6, as well.


FYI, I believe that if one wanted 5G cellular connectivity – on top of the ability to run iOS 17 and 18 – one would want an iPhone 12 series, or newer, phone.
