IT'S THAT time of year when Apple unveils it's big annual update: iOS 18.
It's jam-packed with new features, and will be free to download from September 16.
But there are a handful of things iPhone owners must do to prepare their devices for the system overhaul.
First, check that your device is compatible with the update.
Dozens of devices are capable of running iOS 18, check the full list below to see if you're eligible:
If your device is not listed, then you will not be able to use iOS 18 and it's new features.
On the day a major iOS update arrives, Apple's servers can become overloaded, which can make installing it take longer than usual.
Before iOS 18 arrives, it's wise to update your device to the latest software that is currently available.
This will help make sure that the larger iOS 18 operating system downloads smoothly.
It will also mean your phone is protected against cyber vulnerabilities, as it can be while before the server frenzy dies down.
You may also want to wait a week or so until Apple issues iOS 18.1, which is usually a fix for any bugs that arrive within the first iteration.
It is advised to have at least 15GB of storage space to spare on your iPhone to download iOS 18.
Iterations of iOS 17 currently take up around 11GB of storage on iPhones, while versions of iOS 16 typically took up 10GB.
If that trajectory is anything to go by, iOS 18 is likely to be 12GB or above.
If you don't have enough storage, you should try and make some room.
You can do this a number of ways, such as deleting or offloading unused apps, axing downloaded content or shafting more images and videos onto iCloud.
You may want to back up your iPhone using iCloud, or the Finder on a Mac or iTunes on a PC.
Previously, people have complained that they lost data like old text messages and photos during an update.
The Sun has detailed how you can back up your iPhone prior to an iOS update here.
Right before you hit that download button, you want to ensure your iPhone has enough battery to install the software properly.
If your battery dies while updating critical parts of iOS 18, it may well brick your iPhone.
Bricking is when an electronic device becomes completely unresponsive and can't function.
Fortunately, most devices take about 30 minutes to update - so you don't need masses of charge.
You can set up you iPhone so that it updates automatically overnight while it's charging.
