Where to find and install the new iPhone update

The newest iPhone update arrives on your phone through the Settings app, not through the App Store or any website. Apple pushes updates to all compatible iPhones at the same time, so you do not need to hunt for it — your phone will notify you when one is ready. You can also check manually by opening Settings, tapping General, then Software Update to see if a new version is waiting.

The update downloads automatically when your phone is plugged in, connected to Wi-Fi, and locked (usually overnight). Once downloaded, you will see a notification asking you to install it. You can install when ready or delay for up to seven days, after which your phone will install it on its own. The whole process takes between 15 and 45 minutes depending on the update size and your phone's age.

Key Takeaways

  • New iPhone updates arrive through Settings > General > Software Update, and Apple sends them to all compatible phones at once.
  • Your phone downloads updates automatically when plugged in and on Wi-Fi, then prompts you to install when ready.
  • Installation takes 15 to 45 minutes and requires your phone to stay plugged in and unlocked until it finishes.
  • Older iPhone models may not receive the newest updates, but Apple typically supports phones from the past five to six years.
  • If an update fails or your phone gets stuck, force restart by pressing and releasing volume up, then volume down, then holding the side button until the Apple logo appears.

Checking if your iPhone model receives the update

Not every iPhone receives every update. Apple supports iPhones from roughly the past five to six years, though the exact cutoff changes with each major release. For example, if the newest update is iOS 18, you can check Apple's official support page to see which models are compatible — it will list iPhone 12 and newer, or iPhone 11 and newer, depending on the release.

To learn about your specific phone is compatible, open Settings, go to General, and tap About. Look for the Model name (for example, "iPhone 14 Pro"). Then visit Apple's support website and search for the iOS version number you saw in Software Update. The compatibility list will tell you when ready whether your model is included.

If your phone is too old to receive the update, you have reached the end of support for that device. Apple will not release security patches for it anymore, so using it for sensitive tasks like banking becomes riskier over time. At that point, upgrading to a newer iPhone is the only way to get current updates.

Preparing your phone before you install

Before you start the installation, make sure your phone has enough battery and storage space. Plug it into power — do not rely on battery alone, because if your phone dies during installation, it can become unusable. You need at least 5 to 10 gigabytes of free storage, though the update itself is usually smaller. If you are running low on space, delete old photos, videos, or apps you no longer use.

Back up your phone before installing, especially if you have important photos or messages. The easiest way is to use iCloud: open Settings, tap your name at the top, then iCloud, then iCloud Backup, and tap Back Up Now. This takes a few minutes and stores a copy of your phone's data in the cloud. If something goes wrong during the update, you can restore from this backup.

Close all open apps and avoid using your phone while the update is installing. The installation process needs your phone's full attention. If you interrupt it by opening apps or making calls, the update can fail and leave your phone in an unusable state.

Walking through the installation step by step

Open Settings and tap General. You will see Software Update near the top of the menu. Tap it, and your phone will check for available updates. If a new version is ready, you will see a description of what changed and how much space it needs. Read through the changes if you want to know what is new, then tap Install Now.

Your phone will ask you to agree to the terms and conditions. Scroll through them if you wish, then tap Agree at the bottom. Your phone will begin installing the update. The screen will show a progress bar and an estimated time remaining — this is usually accurate within a few minutes.

Your phone will restart several times during installation. This is normal. Do not unplug it or try to use it while it is restarting. The Apple logo will appear, then disappear, then reappear — this cycle can repeat three or four times. Once the installation finishes, your phone will return to the lock screen and you can unlock it normally. The entire process is now complete.

What to do if the update fails or gets stuck

If your phone gets stuck on the Apple logo for more than 15 minutes, or if you see an error message during installation, try a force restart. Press and quickly release the Volume Up button, then press and quickly release the Volume Down button. Then press and hold the Side button (the power button) until you see "slide to power off" appear, then keep holding it until the screen goes black and the Apple logo appears. Release the button and let your phone restart normally.

If the update fails with an error code, write down the code and visit Apple's support website to search for it. Different error codes mean different things — some indicate a temporary network problem, others a storage issue, and others a problem with Apple's servers. The support page will tell you exactly what the code means and how to fix it.

If your phone remains stuck after a force restart, or if you see the same error code repeatedly, connect your phone to a computer with iTunes or Finder installed. You can restore your phone from a backup through the computer, which often fixes problems that the phone cannot fix on its own. This process erases your phone and reinstalls everything from your backup, so make sure you have a recent backup before you start.

Understanding what changes after you update

After the update installs, your phone will work almost exactly as it did before. Some updates add new features — a new camera mode, a redesigned settings menu, or new privacy controls — while others are mostly security fixes that you will never notice. Open Settings and tap General, then About, and look at the Version number to confirm the update installed correctly. It should match the version you saw before you started.

Your apps may take a few minutes to update themselves after your phone updates. This is normal. Some apps need to adjust to the new iOS version, so you might see them updating in the background for an hour or two after installation. Do not uninstall apps during this time.

If something stops working after the update — an app crashes, Wi-Fi disconnects, or a feature behaves differently — restart your phone first. Many small problems fix themselves with a restart. If the problem persists, check the App Store to see if the app has an update available, or visit Apple's support page to see if other users have reported the same issue.

When updates arrive and how often they come

Apple releases major updates (like iOS 17 to iOS 18) once per year, usually in September. These updates add new features and redesign parts of the interface. Between major releases, Apple sends smaller updates (called point releases, like iOS 18.1 or iOS 18.2) roughly every two to four weeks. These mostly contain security fixes and bug corrections.

You do not need to install every single update when ready. Security updates are important and should be installed within a few weeks, but you can safely wait a week or two after a major update releases to let other users find any problems first. If a major update causes widespread issues, Apple releases a fix within days.

Your phone will keep reminding you to install an update until you do. If you delay for seven days, your phone will install it automatically when plugged in and locked. You cannot permanently skip an update — Apple requires all phones to stay current for security reasons.

Frequently Asked Questions

Can I install the update on cellular data instead of Wi-Fi?

No. Your phone will only read updates over Wi-Fi to avoid using your cellular plan's data allowance. If you do not have Wi-Fi at home, you can use Wi-Fi at a library, coffee shop, or friend's house. The read usually takes 10 to 20 minutes on a normal Wi-Fi connection.

What happens to my photos and messages when I update?

Nothing. Updates do not erase your data. Your photos, messages, contacts, and apps all stay exactly as they are. The update only changes the operating system that runs underneath everything else. If you are worried, back up through iCloud before you start, but data loss during a normal update is extremely rare.

Why does my phone feel slower after the update?

New updates sometimes use more battery and processing power for the first day or two while your phone indexes files and optimizes itself. If your phone is still slow after 24 hours, restart it. If slowness continues, check Settings > General > iPhone Storage to see if you are running low on space — updates need room to work properly.

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

No. Apple does not allow downgrading to older iOS versions. Once you update, you are on that version permanently unless you restore from a backup you made before the update. This is why backing up before you update is important — it gives you a way to go back if something goes seriously wrong.

Do I have to be home to install the update?

You need to be somewhere with Wi-Fi and a power outlet. Your phone downloads automatically when plugged in and on Wi-Fi, so you can leave it plugged in overnight at home. The installation itself takes 15 to 45 minutes, so plan for that time when you are not using your phone.
