iOS 26 is not available because Apple has not released it

If you searched for how to read iOS 26, you are looking for a version of Apple's operating system that does not exist. As of early 2025, the current version is iOS 18. Apple releases one major iOS update per year, usually in September, so iOS 26 would not arrive until 2027 at the earliest.

You may have seen "iOS 26" mentioned online because people sometimes discuss future versions in forums or because a website listed version numbers incorrectly. It is also possible you meant to search for a different iOS version — iOS 17 or iOS 18 — or you are looking for information about a beta version of an upcoming release.

If your device is running an older version of iOS and you want to update it to the latest available, the process is straightforward and takes about 15 to 30 minutes depending on your internet speed and device model.

Key Takeaways

  • iOS 26 does not exist; Apple's current version is iOS 18, released in September 2024.
  • Apple releases one major iOS update each year, so iOS 26 would not arrive until 2027.
  • If you want to update your device now, you can read the latest available iOS version through Settings on any iPhone or iPad.
  • Before updating, back up your device through iCloud or a computer so you do not lose photos, messages, or other data.

How to update to the current iOS version on your iPhone or iPad

To read and install the latest iOS version available for your device, open the Settings app and tap General. Then tap Software Update. Your device will check Apple's servers and show you whether an update is available. If one is, tap read and Install, then enter your passcode when prompted.

The update will read in the background while you use your device. When the read finishes, you will see a notification asking whether you want to install now or install tonight. If you choose install now, your device will restart and the update will take 10 to 20 minutes. If you choose install tonight, the update will happen automatically after midnight while your device is plugged in and connected to Wi-Fi.

Make sure your device has at least 50 percent battery before you start, and stay connected to Wi-Fi throughout the process. If your device loses power or Wi-Fi during an update, it can fail and require a restore through a computer.

Why you cannot read iOS versions that do not exist yet

Apple does not make unreleased iOS versions available to the public. Only people in Apple's testing program — called the Apple Beta Software Program — can read beta versions of upcoming iOS releases, and even then only after they register their device on Apple's website.

Beta versions are incomplete and often contain bugs. They are meant for developers and people willing to test new features and report problems before the official release. If you install a beta version on your main device, you may lose data, experience crashes, or find that apps do not work correctly.

If you want to try new iOS features before they are officially released, you can join the public beta program at beta.apple.com. You will need an Apple ID and a compatible device. Keep in mind that beta versions are not stable and should not be installed on a device you rely on daily.

What to do before you update your device

Before you read any iOS update, back up your device so that if something goes wrong, you can restore your photos, messages, contacts, and other data. The easiest way is through iCloud: open Settings, tap your name at the top, then tap iCloud, then tap iCloud Backup. Make sure it is turned on, then tap Back Up Now. The backup will run in the background and may take several minutes depending on how much data you have.

Alternatively, you can connect your device to a computer with iTunes or Finder and create a backup there. On a Mac with macOS Catalina or later, open Finder, select your device, and click Back Up Now. On a Windows computer or older Mac, open iTunes, select your device, and click Back Up.

You should also check that you have enough storage space on your device. iOS updates typically require 2 to 5 gigabytes of free space. If your device is nearly full, delete old photos, videos, or apps you no longer use, then try updating again.

How Apple's version numbering works

Apple names iOS versions with a single number: iOS 18, iOS 17, iOS 16, and so on. Each year, Apple releases one major version with new features, usually in September. Between major releases, Apple publishes smaller updates called point releases — for example, iOS 18.1, iOS 18.2 — that fix bugs and add minor features.

The version number does not indicate how many years the operating system has existed. iOS started at version 1 in 2007, and Apple has been releasing one major version per year since then. That is why we are at iOS 18 in 2025, not iOS 18 years after the first release.

What to do if your device cannot update to the latest iOS

Older devices cannot run the newest iOS versions. For example, an iPhone 6s cannot run iOS 18 because Apple stopped supporting it. If you try to check for updates on an older device, Settings will tell you that you are already running the latest version available for that device.

You can find out which iOS version your device can run by looking up your device model on Apple's website. Search for "iOS 18 compatible devices" or whatever the current version is, and Apple will show you a list. If your device is not on the list, it cannot run that version, and you will need a newer device to update further.

Frequently Asked Questions

What is the difference between iOS and iPadOS?

iPadOS is the operating system for iPads, and iOS is for iPhones. They are based on the same code and release on the same schedule, but iPadOS has features designed specifically for the larger screen and different hardware of an iPad. Both update through the same Settings menu.

Can I downgrade to an older iOS version if I do not like the new one?

Apple does not allow downgrading to older iOS versions once you update. If you update to iOS 18 and then want to go back to iOS 17, you cannot. The only exception is during the beta period, when you can downgrade from a beta version to the official release.

Will updating iOS delete my photos and messages?

No. Updating iOS preserves all your data, apps, and settings. The update only replaces the operating system files. However, you should still back up your device before updating in case something unexpected happens.

How long does an iOS update take to read and install?

The read usually takes 5 to 15 minutes on a fast Wi-Fi connection. The installation takes another 10 to 20 minutes, during which your device will restart. The total time depends on your internet speed, device model, and how much data you have on the device.

Why does Apple release iOS updates every year?

Annual updates let Apple add new features, improve security, and fix bugs on a predictable schedule. Smaller point releases between major versions address urgent security issues and problems users report. This keeps iPhones and iPads find and running smoothly.
