Usually you’re looking this up for a reason. An app says it needs a newer version, a guide you’re following assumes something you don’t have, or you just want to know whether your iPhone is still getting updates. Whatever brought you here, it takes about ten seconds to find out.
The Quickest Way to Check
- Open Settings.
- Tap General.
- Tap About.
- Look for iOS Version near the top. On an iPad it’ll say iPadOS Version.
You’ll see something like 26.5.2. The first number is the major release, and the numbers after it are the smaller updates Apple pushes out through the year for bug fixes and security patches.
Faster still: pull down on your home screen to open search, type “About,” and tap the result. It drops you straight there.
Why Your iPhone Says iOS 26 and Not iOS 19
This confuses a lot of people, so it’s worth explaining.
Apple used to number iOS one release at a time: 15, 16, 17, 18. Then it skipped straight from iOS 18 to iOS 26. Nothing went missing. Apple switched to naming its software after the release season instead, so everything shipped in the 2025 to 2026 cycle carries the number 26, whether it’s iOS 26, iPadOS 26, macOS 26, or watchOS 26. It’s meant to make the whole lineup easier to keep track of.
So if your iPhone jumped from 18 to 26 overnight, that’s normal. You didn’t miss seven updates.
iPhone Runs iOS, iPad Runs iPadOS
Since 2019, Apple has split the two. Your iPhone runs iOS and your iPad runs iPadOS. They share most of the same foundations and get updated at roughly the same time with matching version numbers, but they’re separate systems, and iPadOS has extra features built around the bigger screen.
Practically speaking, it changes nothing about how you check. Same Settings, same General, same About screen. Just don’t be surprised when your iPad doesn’t say “iOS” anywhere.
What’s Current Right Now
| Version | Released | The headline change |
|---|---|---|
| iOS 26 | September 2025 | Liquid Glass redesign, call screening, live translation |
| iOS 18 | 2024 | Home screen customisation, first Apple Intelligence features |
| iOS 17 | 2023 | StandBy mode, NameDrop, Contact Posters |
| iOS 16 | 2022 | Lock screen widgets, unsend and edit in Messages |
| iOS 15 | 2021 | Focus modes, redesigned notifications, SharePlay |
Apple keeps releasing point updates within iOS 26 through 2026, so your exact number will be something like 26.5 or 26.6 depending on when you last updated. The next major release, iOS 27, is expected around September 2026.
Worth knowing: iOS 26 runs on the iPhone 11 and newer, along with the second-generation iPhone SE and later. If your iPhone is older than that, you’re capped at iOS 18 and won’t get 26 no matter how many times you check for updates.
Checking From a Computer
You almost never need to do this, but if your iPhone’s screen is broken or unresponsive, here’s how:
- On a Mac: connect your iPhone, open Finder, select your device in the sidebar, and the iOS version appears in the summary at the top.
- On Windows: install the Apple Devices app from the Microsoft Store, connect your iPhone, and select it. Apple has been moving Windows users off iTunes and onto this app, though iTunes still works if you already have it installed.
One small note on cables: iPhone 15 and newer use USB-C, while iPhone 14 and older use Lightning. Grab the right one before you start wondering why nothing is connecting.
Do You Need an App for This?
No. Some older guides suggest downloading a system information app to check your iOS version, and there’s really no reason to. It’s already in Settings on every iPhone and iPad ever made. Installing an extra app just to read a number you already have access to means more permissions and more clutter for nothing.
How to Update to the Latest Version
- Connect to Wi-Fi. These downloads are large and will eat your data otherwise.
- Go to Settings > General > Software Update.
- Tap Download and Install if something is waiting.
- Keep your phone charging and leave it alone. It’ll restart by itself when it’s done.
If it tells you your software is up to date but you know a newer version exists, your device has reached the end of its support window. Nothing is broken, Apple has just stopped issuing updates for that model.
While you’re in there, it’s worth turning on automatic updates so security patches land without you thinking about it. Our guide on why regular software updates matter explains what you’re actually protecting yourself from, and a few simple phone security habits go a long way if you’re holding onto an older device.
Why Your Version Number Matters
- App compatibility. Apps set a minimum iOS version. Fall below it and the app either won’t install or will stop updating.
- Security. Most iOS updates are mostly security fixes. Skipping them leaves known holes open.
- Features. Things like call screening and live translation arrived with iOS 26. If you don’t have them, your version is the reason.
- Troubleshooting. Support articles and guides constantly say “on iOS 17 or later.” Knowing your number saves you from following steps that don’t apply.

Frequently Asked Questions
What is the latest iOS version?
iOS 26 is the current generation, released in September 2025, with point updates continuing through 2026. iOS 27 is expected around September 2026.
Why did Apple skip from iOS 18 to iOS 26?
Apple switched to naming its software after the release season rather than counting releases one by one. Everything from the 2025 to 2026 cycle uses 26, across iOS, iPadOS, macOS, and watchOS.
My iPad doesn’t say iOS anywhere. Is something wrong?
No. iPads have run iPadOS since 2019. It’s the same About screen, just a different name.
Can I go back to an older iOS version if I don’t like the new one?
Generally no. Once an update is installed, Apple doesn’t support downgrading, which is a good reason to read up on a major update before installing it.
Settings, General, About. That’s all it takes. If the number you see is a full generation behind, check for an update while you’re there, since it’s usually security fixes you’re missing rather than features.
