How to download iOS 18: Get the latest iPhone update now

Over three months after Apple’s announcement at WWDC24, iOS 18 is now finally available to download on compatible iPhones.

iOS 18 promises heaps of new features including icon customisation, huge updates to the Messages app, including support for RCS and the ability to schedule messages for later, and perhaps the most exciting: Apple Intelligence.

While iPhone XRs and later will run iOS 18, only the iPhone 15 Pro, 15 Pro Max and the iPhone 16 series will support Apple Intelligence.

Troubleshooting

Can I download iOS 18 without Wi-Fi?

No, you cannot use mobile data to download iOS 18 and will need a stable Wi-Fi connection. You may be able to use a hotspot connection, but be wary as this might take a while to download.

How long will iOS 18 take to download?

The exact amount of time it will take to download iOS 18 mainly depends on the speed of your internet, as well as the number of other iPhone users currently downloading the update. It can be pretty slow at launch, but the process speeds up over the first few hours as keen fans download and install the update.

As you won’t be able to use your iPhone while the update is installing, if you’re concerned about it taking too long during the day then it’s advisable to schedule the download for overnight.
