The good news is that you don’t need a particularly new iPhone to get access to iOS 15. True to form, the iOS 15 upgrade encompasses a broad number of devices, with the iPhone 6S continuing to impress with its longevity. You can download iOS 15 on the following devices:

Back up before you begin

So, you’ve got your eligible iPhone ready — but before you start on the iOS 15 road, make sure to back your device up first. That way, if data is lost, you can quickly and easily restore it with your backup. We have a guide on how to back up an iPhone, but we’ve also put these instructions down below.

iCloud is probably the easiest way to back up your iPhone because you don’t need to attach any cables. All you need is an internet connection.

Step 1: Connect to a Wi-Fi network.

Step 2: Head to your Settings app, then select your name.

Step 3: Tap iCloud. If you’re on iOS 10.2 or earlier, you’ll have to scroll down and tap iCloud.

Step 4: Scroll down and select iCloud Backup > Back Up Now. If you’re on iOS 10.2 or earlier, just tap Backup and it’ll work its magic.

You can check the backup by heading to Settings, hitting iCloud > iCloud Storage > Manage Storage, and tapping on your device from the list.

MacOS 10.15 Catalina did away with iTunes, but backing up on Mac is still easy.

Step 2: Follow the on-screen instructions to enter your device passcode or Trust This Computer.

Step 3: Open Finder, and use the sidebar to select your iPhone.

If you’re using an older Mac or a Windows PC, you’ll have to use iTunes to back up your iPhone or iPod Touch.

Step 1: Make sure iTunes is up-to-date and connect your device.

Step 2: Follow the on-screen instructions to Trust This Computer or enter your device passcode.

Step 3: Select your iPhone or iPod Touch from the iTunes menu.

Step 4: Hit Back Up Now to save your data.

Downloading and installing iOS 15

Step 1: Go to Settings > General > Software Update.

Step 2: Tap Download and Install, enter your passcode, and wait for the update to download and install.

Step 3: Your device will restart during the process, so make sure to keep an eye on it and follow any prompts it brings up.
