How to get the new iPhone update

The newest iPhone update arrives on your phone through the Settings app, not through the App Store. Go to Settings > General > Software Update, and your phone will check whether a new version is available. If one is, you'll see it listed with its version number (like iOS 18.2) and the file size. Tap Download and Install to begin. Your phone needs to be plugged in or have at least 50% battery, and you'll need a Wi-Fi connection — cellular data won't work for the download.

The entire process usually takes 15 to 45 minutes depending on the update size and your Wi-Fi speed. Your phone will restart several times during installation, and you'll see a progress bar on the screen. Don't unplug it or force it off during this time. Once installation finishes, you'll be back at your home screen with the new version running.

Key Takeaways

  • Open Settings > General > Software Update to check for and download new iPhone updates directly on your device.
  • Your phone must be connected to Wi-Fi, plugged in or nearly fully charged, and have enough storage space for the download.
  • The installation process takes 15 to 45 minutes and involves automatic restarts — do not interrupt it by unplugging or turning off your phone.
  • If an update fails to install, restarting your phone and trying again from Settings usually resolves the problem.
  • You can check what version of iOS you're currently running in the same Settings > General > Software Update menu.

Why your phone might not show an available update

Not every iPhone gets the newest update on the same day. Apple releases updates in stages, so your phone might not see it for a few days or even a week after the announcement. This is intentional — it lets Apple catch problems on a smaller group of devices before rolling it out to everyone.

If you've been checking for several days and still don't see an update, your phone may already be running the latest version. Go to Settings > General > Software Update and look at the top of the screen. If it says "Your software is up to date," you have the newest release available for your device. Older iPhone models sometimes don't receive the latest updates at all — an iPhone 8, for example, cannot run iOS 18 even though newer models can.

Storage space and what to do if you don't have enough

iPhone updates need temporary space on your phone to download and install. If you're low on storage, the download might fail or not appear as an option. You can check how much space you're using by going to Settings > General > iPhone Storage. The bar at the top shows your total capacity and what's being used.

If you're running low, delete apps you don't use regularly, clear out old photos and videos, or empty your Recently Deleted folder in Photos (which still takes up space until permanently removed). You don't need to free up gigabytes — usually 2 to 3 GB of available space is enough. After you've made room, go back to Software Update and try downloading again.

What happens if the installation fails or gets interrupted

If your phone loses power, Wi-Fi drops, or something else interrupts the installation, you'll usually see an error message. The most common ones say "Unable to Install Update" or "Software Update Failed." Your phone is still safe — a failed update won't break it or delete your data.

The first step is to restart your phone by holding down the power button and sliding to power off, then turning it back on. Once it's restarted, go back to Settings > General > Software Update and try downloading again. Make sure your phone is plugged in this time and connected to a strong Wi-Fi signal. If it fails a second time, try connecting to a different Wi-Fi network if you can — sometimes a particular network has issues with large downloads.

Automatic updates and how to turn them on or off

You can set your iPhone to download and install updates automatically at night when you're not using it. Go to Settings > General > Software Update > Automatic Updates and toggle on Download iOS Updates and Install iOS Updates. Your phone will download the update when plugged in and connected to Wi-Fi, then install it overnight.

This is convenient if you want updates without thinking about them, but you lose control over when your phone restarts. If you prefer to choose when to install updates, leave these toggles off and check manually when you're ready. Either way, your phone will eventually push you to update — Apple stops supporting very old versions after several months.

Checking what version you have and what changed

To see exactly which iOS version is running on your phone right now, go to Settings > General > About. Look for the line that says "Software Version" — that's your current iOS number. You can also see your phone model, storage capacity, and other technical details on this same screen.

If you want to know what's new in an update before you download it, the Software Update screen shows a brief description of improvements and security fixes. For a more detailed list, you can visit Apple's security updates page on their website and search for the version number. This tells you which vulnerabilities were patched and what features were added or changed.

Frequently Asked Questions

Can I use my phone while it's updating?

No. Once the installation starts, your phone will restart and be unusable until it finishes. The entire process takes 15 to 45 minutes. Plan to update when you won't need your phone for at least an hour to be safe.

Will updating delete my photos, contacts, or other data?

No. Updates only change the operating system software, not your personal data. Your photos, messages, contacts, and apps all stay exactly as they are. The update is like replacing the engine in a car — the contents stay the same.

What if my iPhone is too old to get the new update?

Apple stops supporting iPhones after about five to six years. If your phone is older than that, it may not be able to run the newest iOS version. Check the Software Update screen — if it says your software is up to date but you're several versions behind what you see online, your phone has reached the end of its update cycle.

Do I have to update, or can I stay on an older version?

You can delay updates, but not indefinitely. After several months, Apple stops supporting older versions and may prevent you from using certain apps or features. Security fixes also stop arriving for old versions, which leaves your phone more vulnerable to problems. Eventually you'll need to update to keep your phone secure and functional.

Why is my update taking so long?

Large updates can take 30 to 45 minutes, especially on slower Wi-Fi. If it's been over an hour and still showing progress, your connection may have dropped. Restart your phone and try again, making sure you're connected to a strong Wi-Fi signal and the phone is plugged in.
