Update the iOS Software on Your iPhone, iPad or iPod touch
Be sure to keep your iPhone, iPad and iPod up to date so that you don’t miss out on the latest features.
Before you update your device, back it up to iTunes or iCloud. 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.
The easiest way to update the device is wirelessly (over the air) is as follows (if you use a passcode, you’ll need to enter it before installing the update) – Plug in your device to a power source, Tap Settings > General > Software Update. Next tap Download and Install (or tap Later to install the update later).
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.
If you have not enough space to update over the air, you can either update using iTunes or delete content manually. Whether you use iTunes or update wirelessly, you’ll have the same amount of free space on your device after you update.
If you can’t update wirelessly, or if you want to update with iTunes, do the following: Install the latest version of iTunes on your computer, then plug in your iPhone, iPad or iPod touch to your computer. Next, in iTunes, select your device. In the Summary pane, click Check for Update. Click Download and Update. If you don’t have enough free space to update using iTunes, delete some content manually from your device.
Note: When you use iTunes to update iOS on your Apple device, you might see an error code or alert message. Most of these errors happen because your computer has older versions of software or can’t connect to the server, and you can fix most update and restore errors with a few simple steps.
