How do I update my iPhone 6 to the latest iOS version?

You trade it in for an iPhone that can run iOS 18. An iPhone 15 or 16 would be recommended if you want to be good to go for software updates for the next 5-7 years.

You do not update your iPhone 6 to the latest iOS version.

The iPhone 6 cannot update to iOS 13, let alone to iOS 18. All iPhones that can run iOS 18 have 3 – 8 GB of RAM and Neural Engines. The iPhone 6 has an older, slower processor; 1 GB of RAM, and no Neural Engine. It simply lacks the horsepower to run iOS 18. This cannot be fixed except by replacing the phone.

If you want to run iOS 18, you will need to purchase a new phone compatible with it, such as an iPhone 15 or 16-series phone.

If you want Apple Intelligence, that is only on

• The iPhone 15 Pro and Pro Max (now discontinued)
• The iPhone 16-series phones

These are the iPhones with the newest processors and the only ones with 8 GB of RAM.

The latest iOS that the iPhone 6 can get is 12.
