How do I update my iPhone 6S Plus?

Your 6S plus can be updated to iOS 15.8.2, no further.

If you want to run a higher operating system, you will need 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

Hi Jonathanbernales_,

The iPhone 6 Plus is an old iPhone and no longer supports the most recent iOS versions. The app you’re trying to download most likely needs the latest iOS updates to work which means you’d need a new iPhone.

Does it tell you what version you need? From a quick search it looks like the iPhone 6 Plus can only go to iOS 12.
