Update the iOS software on your iPhone, iPad, and iPod touch
Update your device wirelessly
The easiest way to update your device is wirelessly, also called “over the air.” Here’s how:
- Plug in your device to a power source.
- Tap Settings > General > Software Update.
- Tap Download and Install. Updates might download automatically while your device is connected to Wi-Fi and a power source.
- 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.
