Which iPhones Will Not Support iOS 17

In general, Apple releases a new major iOS update every September or October. In addition, it will discontinue support for iPhone models over six years old and will no longer provide updates to the latest iOS for these devices.

In June 2023, Apple announced that iPhone 8, iPhone 8 Plus, and iPhone X will no longer be able to upgrade to iOS 17. (iOS 17 will only support iPhone models powered by the A12 chip or higher.)

What Happens When Support for the Latest iOS Ends?

When the latest iOS support ends, the risk of security and functionality issues increases. Therefore, it is important to update to the latest iOS version whenever possible.

However, if your iPhone is unable to update to the latest iOS version, it is recommended to buy a new iPhone.

How to Find the Software Version on Your iPhone

Follow the steps below to check your iOS version:

Go to Settings>General>About This iPhone.

To update your iPhone:

Go to Settings>General>Software Update.

What Happens If the iOS Version Is Old?

If you are running an old iOS version, you may experience the following problems:

Security Risk: Old iOS versions do not have the latest security measures applied, increasing the risk of unauthorized access or information leakage.

Application Compatibility Issues: Some apps may not be compatible with old iOS versions, making part of their functions unable to work.

Communication Issues: Old iOS versions may experience difficulty receiving a 4G signal or internet connection issues.

Lack of Latest Features: Newer apps and services may require the latest iOS features.

Lack of Security Updates: Old iOS versions may not provide updates for discovered vulnerabilities or security issues.

Unsupported New Features: Newer iOS versions may add new features, but old iOS versions may not have access to these new features.

For these reasons, it is important to update your iOS regularly and use the latest iOS version.
