Update your iPhone, iPad, or iPod touch

Learn how to update your iPhone, iPad, or iPod touch to the latest version of iOS or iPadOS.

You can update your iPhone, iPad, or iPod touch to the latest version of iOS or iPadOS wirelessly.

If you’re using iOS or iPadOS 14.5 or later, you might now see the option to choose between two software update versions. This option allows you to choose between updating to the latest version of iOS or iPadOS 15 as soon as it’s released, or continuing on iOS or iPadOS 14 while still getting important security updates for a period of time.

If you can’t see the update on your device, you can update manually using your computer. Learn how to update your device manually if you’re using a Mac with macOS Catalina or later, or if you’re using a Mac with macOS Mojave or earlier or a Windows PC.

Before you update

Back up your device using iCloud or your computer.

Update your iPhone, iPad, or iPod touch wirelessly

If a message says that an update is available, tap Install Now to update now. Or you can tap Later and choose Install Tonight or Remind Me Later. If you tap Install Tonight, just plug your device into power at night, and your device will update automatically overnight.

You can also follow these steps:

1. Plug your device into power and connect to the internet with Wi-Fi.
2. Go to Settings > General, then tap Software Update.
3. If you see two software update options available, choose the one that you want to install.
   
4. Tap Install Now. If you see Download and Install instead, tap it to download the update, enter your passcode, then tap Install Now. If you don’t know your passcode, learn what to do.

You might see that your device is up to date on its current version, and there’s an update available. For example, even if your device is up to date on the latest version of iOS 14, there might be an option to update to iOS 15.

If you see an alert when updating wirelessly

Some software updates aren’t available wirelessly. VPN or proxy connections might prevent your device from contacting the update servers.

If you need more space when updating wirelessly

If a message asks to temporarily remove apps because the software needs more space for the update, tap Continue to allow apps to be removed. After installation is complete, those apps are automatically reinstalled. If you tap Cancel instead, you can delete content manually from your device to add more space.

Customize automatic updates

Your device can update automatically overnight while it’s charging. Here’s how to turn on automatic updates:

1. Go to Settings > General > Software Update.
2. Tap Automatic Updates, then turn on Download iOS Updates.
3. Turn on Install iOS Updates. Your device will automatically update to the latest version of iOS or iPadOS. Some updates might need to be installed manually.
   

Upgrading to the latest version of iOS or iPadOS software provides the latest features, security updates, and bug fixes. Not all features are available on all devices or in all regions. Battery and system performance may be influenced by many factors including network conditions and individual use; actual results may vary.

If your iPhone, iPad or iPod touch won’t update

You might be unable to update your iPhone, iPad, or iPod touch wirelessly—or over the air—for one of these reasons.

• Not enough available storage space on your device
• Downloading the update takes a long time
• Unable to reach the update server
• The update doesn’t complete

If there’s not enough space to update

If there isn’t enough space to download and install an update, the software on your device will try to make space. It will remove only app data that it can download again and doesn’t remove or relocate any of your data. If your device still doesn’t have enough space, you can use your computer to update your device.

If you can’t connect your device to your computer, you can make room for the update by removing content and apps on your device that you don’t use. Go to Settings > General > [Device name] Storage.

If the download takes a long time

You need an Internet connection to update your device. The time it takes to download the update varies according to the size of the update and your Internet speed. You can use your device normally while downloading the update, and your device will notify you when you can install it. To improve the speed of the download, avoid downloading other content and use a Wi-Fi network if you can.

If you can’t reach the update server or can’t verify the update

If you try to update your device, you might see one of these messages:

«Unable to Check for Update. An error occurred while checking for a software update.»

«Unable to Install Update. [Software] update requires a network connection.»

Try updating your device again using the same network. If you still see one of these messages, try updating your device using another network or update your device with your computer. If the issue happens again after trying to update with multiple networks, remove the update.
