One of the biggest benefits of owning an iPhone is Apple's long software support cycle. Some iPhones receive updates for six years or more, while older models can continue receiving security patches long after major iOS support ends.

But in 2026, not every iPhone is treated equally.

Some devices can run the latest iOS versions, some only receive security updates, and others have reached the end of their life entirely.

Here's what you need to know.

As of 2026, the oldest iPhone that can run the latest version of iOS is the iPhone 11.

The following devices support iOS 26 and are expected to support iOS 27:

• iPhone 17 Series
• iPhone 16 Series
• iPhone 15 Series
• iPhone 14 Series
• iPhone 13 Series
• iPhone 12 Series
• iPhone 11 Series
• iPhone SE (3rd Generation)
• iPhone SE (2nd Generation)

If your iPhone is on this list, you're still receiving Apple's newest features, performance improvements, and security updates.

These devices cannot install the latest version of iOS but may still receive occasional security patches:

iPhone XR: Security Updates Only

iPhone XS: Security Updates Only

iPhone XS Max: Security Updates Only

These phones are still usable today, but they're no longer receiving major new features from Apple.

The following models are becoming increasingly difficult to recommend because support is limited and may end soon:

• iPhone X
• iPhone 8
• iPhone 8 Plus
• iPhone 7
• iPhone 7 Plus
• iPhone SE (1st Generation)
• iPhone 6s
• iPhone 6s Plus

Many of these devices only receive limited security updates through older iOS versions.

If you're shopping for a used iPhone, we generally recommend avoiding:

• iPhone XR
• iPhone XS
• iPhone XS Max
• iPhone X
• iPhone 8 Series
• iPhone 7 Series
• iPhone 6s Series

While these devices may still work, their remaining software support is limited. That means less security, fewer app updates, and a shorter lifespan.

Apple classifies older devices into two categories:

Vintage

Products that Apple stopped selling between five and seven years ago.

Examples include:

• iPhone 7
• iPhone 8
• iPhone X
• iPhone XS
• iPhone 11 Pro

Apple may still offer repairs if replacement parts are available.

Products that Apple stopped selling more than seven years ago.

Examples include:

• iPhone 6
• iPhone 6 Plus
• iPhone 5s
• iPhone 5c
• iPhone 5
• iPhone 4 Series

Apple no longer provides repair services or replacement parts for these devices.

While Apple doesn't publish exact dates, industry estimates suggest

iPhone 11: 2027–2029

iPhone SE (2nd Gen): 2027–2029

iPhone 12: 2028–2030

iPhone 13: Around 2032

iPhone SE (3rd Gen): Around 2033

iPhone 14: Around 2034

iPhone 15: Around 2035

iPhone 16: Around 2036

iPhone 17: Around 2037

Keep in mind these are estimates and Apple can extend or shorten support depending on hardware requirements.

Apple Intelligence has created another reason to upgrade.

Even some iPhones that receive the latest iOS updates cannot use Apple's AI features.

Currently, Apple Intelligence is available on:

• iPhone 15 Pro
• iPhone 15 Pro Max
• iPhone 16 Series
• iPhone 17 Series

If AI features matter to you, software support alone isn't enough, you'll also need compatible hardware.

If you're using an iPhone XR, XS, X, or older device, now may be a good time to consider upgrading.

Newer models offer:

• Longer software support
• Better battery life
• Improved cameras
• Faster performance
• Apple Intelligence compatibility

In 2026, the iPhone 11 is the oldest iPhone that can still run the latest version of iOS. While devices like the iPhone XR and iPhone XS continue receiving limited security updates, they have effectively reached the end of their major software support lifecycle.

If you're using one of these older devices, upgrading now can help ensure you continue receiving the latest features, security protections, and Apple Intelligence capabilities for years to come.
