Update the iOS software on your iPhone, iPad, and iPod touch

earn how to update your iOS device wirelessly or using iTunes.

iOS software updates introduce new features that let you do even more with your iPhone, iPad, or iPod touch. Be sure to keep your devices up to date so that you don't miss out on the latest features.

Before you update

Back up your device to iCloud or iTunes.
If you use your device's Personal Hotspot for your computer's Internet connection, update your device wirelessly or connect your computer to another network.

Update your device wirelessly

The easiest way to update your device is wirelessly, also called “over the air.” Here’s how:

1. Plug in your device to a power source.
2. Tap Settings > General > Software Update.
   
   
   
3. Tap Download and Install. Updates might download automatically while your device is connected to Wi-Fi and a power source.
4. Tap Install, or tap Later to install the update later. If you use a passcode, you'll need to enter it before installing the update.
   

If you have some free space, but not enough to update over the air, you can either update using iTunes or delete content manually from your device. Whether you use iTunes or update over the air, you'll have the same amount of free space on your device after you update.
Some iOS software updates aren't available as over-the-air updates. VPN or proxy connections might prevent your device from contacting the iOS update servers.

Update your device using iTunes

If you can’t update wirelessly, or if you want to update with iTunes, follow these steps:

1. Install the latest version of iTunes on your computer.
2. Plug in your device to your computer.
3. In iTunes, select your device.
4. In the Summary pane, click Check for Update.
   
5. Click Download and Update.

If you don't have enough free space to update using iTunes, you'll need to delete content manually from your device
