How to update iOS on iPhone or iPad

Find out how to update your iPhone or iPad to the latest version of iOS, getting dozens of cool new features for free

iOS 10 launched on 13 September 2016, bringing with it a number of new additions and refinements; since then Apple has launched a series of smaller upgrades with patches and minor new features. All have been made available to iPad & iPhone users for free (assuming your device is a recent enough model to qualify).

If you've yet to make the move to iOS 10, or just want to ensure you have the latest version of it on your device, this article is for you: we show you how to make the update quickly, easily and safely.

We take you through how to download, install and run the latest version of iOS on your iPhone and iPad, potential problems you may encounter, and whether you should let Apple update your iPhone or iPad for you overnight.

And a warning: bear in mind that if you do change your mind afterwards, it may be too late to go back. We discuss the methods used to achieve this in our article How to remove iOS 10 and go back to iOS 9, but they are dependent on Apple still 'signing' the old version... and that is no longer the case for iOS 9 or most of the earlier builds of iOS 10.

iOS updating basics

iOS is the operating system software that runs on iPad, iPhone and iPod touch devices. It's the underlying framework that organises, launches and runs other apps, and can perform a number of features of its own. Read next: How to set up a new iPad

Every summer at WWDC Apple unveils the latest big update to iOS; in June 2017 we will therefore hear about iOS 11. Then we all get to download the new OS in September of the same year. There will be smaller point updates throughout the year: iOS 11.1 and so on.

At time of writing the latest version is iOS 10.3.2. When you update your device to iOS 10 you will automatically get the most recent version that is available.

Can my iPhone or iPad run iOS 10?

Before updating, you need to make sure your device is certified as capable of running the new software. To run iOS 10 you'll need an iPad 4 or later, an iPad mini 2 or later, an iPhone 5 or later, or the sixth-gen iPod touch.

Preparing for the upgrade

We're about to walk you through the update process. But before we get to that, here are the steps you should take before you click yes on that update alert. (My colleagues look at a couple of aspects of this in a little more depth in a separate article: How to prepare your devices for iOS 10.)

1) Back up your data

Use iCloud or iTunes to back up your iPhone, iPad or iPod touch. This will save the day if you find that messages or photos disappear from your iPhone after the update.

Beware: the backup will include purchased music, TV shows, apps, and books; photos and video in the Camera Roll; and device settings, but it won't include anything you synced from your computer. To re-sync that stuff you'll need to sync with iTunes. For that reason we recommend backing up to your computer as well as iCloud.

2) Save a copy of the old version of iOS

As a general principle this is a sensible idea - you may change your mind and decide you want to downgrade from iOS 10 to iOS 9, and this will be easier if you make sure you've got a copy of the latest version of iOS 9 compatible with your device. But Apple is no longer signing iOS 9 (or or most versions of iOS 10, in fact - at time of writing the currently signed versions are 10.3.1 and 10.3.2) so it will be impossible to downgrade in any case.

For future reference, if you have a copy on your hard drive you will find it, by default, by following this path: youruserfolder/Library/iTunes and then select the Software Updates folder for your device. (Access the Library folder in your user folder by holding down the Option key in Finder and selecting Go > Library.)

Your Mac may have deleted this file, however. If so, launch your web browser and search for download ipsw. You'll find a number of sites offering links to the file you need. Make sure you get the right one for the device you use.

3) Make room on your device

If you have limited space on your phone you may not be able to perform the update - it's a fairly hefty download. To get ready, you can remove content you no longer need, which is a good idea in any case. See our guide to making room on your iPhone or iPad. Alternatively, you can update iOS in iTunes and save yourself the trouble.

4) Plug in your iPhone or iPad

Make sure you plug your device into a power source. Running out of battery mid-download can foul up the update.

5) Make sure you're connected to Wi-Fi

Be sure that you're downloading over Wi-Fi and not via 3G or 4G, or you may end up using up all your data for the month. Read our guide: how to stop running out of cellular data.

How to install iOS 10

It's very easy to update your iPhone or iPad to the latest version of iOS, although it may take a few hours.

1) Go to Settings > General > Software Update

You should get a notification informing you that a new version of iOS is available for you to download, then all you need to do is confirm that you're happy to update your device. But if not, take a look in the Settings app and scroll down to General. Tap Software Update and force iOS to check for new updates.

iOS will think for a moment and then present you with the update, including the amount of storage space required (you may need to clear some space before downloading) and a link to a 'Learn more' article that tells you about the changes. Simply confirm you wish to upgrade and follow the steps.

2) Tap Download

Your device may or may not have downloaded the install file automatically.

3) Leave the update to download in the background

Once the download has finished you will receive a notification saying an update is available for your device.

4) Tap Details

This will take you to Settings > General > Software Update.

5) Tap Install Now

The iPhone or iPad will now start to install the iOS update.

You can choose to leave the installation for later. Settings will display a notification badge until you have installed the update.

Fixes for common update problems

Updating iOS is generally easy, but there are lots of small things that can potentially go wrong. Read next: iOS 10 troubleshooting

Update is taking too long

We had a complete nightmare installing iOS 7 in 2013 - it took us all night. We had hoped things might go a bit smoother in 2014 with the launch of iOS 8. But unfortunately not. Again, many faced installation dramas because Apple's servers seemed unable to cope with the sheer number of people trying to access them to get the download. So if this was your experience it's not a huge surprise, and you shouldn't feel like you're alone.

One thing is for sure: if you choose to update as soon as a new version of iOS 8 launched you're probably in for a long wait because the first few hours of an update are always the busiest time on Apple's servers.

With iOS 10 now having been available for several months there should be no problems with busy servers or long delays. But as each iteration of iOS 10 comes out, we recommend giving it a few days just to let the clamour die down and any bugs get ironed out before you put it on your device.

Not enough space on iPhone or iPad

All that presumes you had enough space on your iPhone to start with. A common problem when updating your version of iOS is to find that there isn't room on your device for the install file. One solution is to delete lots of files from your iPhone and make room, then put them back afterwards. Another option is to update iOS via iTunes on your Mac.

If you don't need to free up a lot of space you may be happy to delete a few images from your Camera Roll or some of your music. You might find it useful to read our guide to saving space on your iPhone here.

We explain this relatively painless process in a separate article: How to update iOS on your Mac.

Should you let iOS update your iPhone or iPad overnight?

Apple is keen for more users to install incremental iOS updates that provide fixes and small improvements. One way it encourages this is by offering the chance to install them for you overnight while you're sleeping. If you're prompted to update your iPhone while you're using it, Apple now lets you choose 'Later,' which will then specify a time period during which it will update automatically for you if you've got your iPhone plugged in to a power source, which most people do overnight anyway.

When Apple prompted Macworld's own Ashleigh Macro to update to iOS 9.1 and offered that 'Later' option, she decided to make the most of the convenient new feature. She expected to wake up in the morning as usual to an updated iPhone. And indeed she did, but she woke up more than an hour after her alarm was scheduled to go off. The update had worked brilliantly, but her alarm had been deactivated, causing her to be very late for work.

She's not the only one. Users have taken to social media and forums to express their annoyance with the issue, which we consider to be a bug, and many have been late for important meetings and school.

Therefore, we'd only recommend choosing the later option if you don't have to wake up at a particular time in the morning, or if you can set another alarm on a different device!

Beta versions of iOS

Before a new version of iOS is launched to the general public, it will be made available to a smaller pool of users for pre-release testing. These testing versions are called betas.

There are various reasons why you might want to download a beta version of iOS, but generally it's because the public version hasn't come out yet. Every version of iOS, including the point releases (10.1, 10.2, 10.3 etc.) enter beta testing before they go on general release.

At WWDC 2017 Apple will announce iOS 11 and show off its new features, but it won't launch until September 2017. If you want to try it out before then you'll need to join the beta programme, which should be launched during or shortly after the WWDC keynote.

Downloading an iOS beta is more complicated than getting the final public-release version, unfortunately. We address it in a separate article: How to install a beta version of iOS.
