The iOS 9 is coming, upgrading to iOS 9 is simple, but there are a few handy things to know before you begin which we've listed below in this guide.
Check your device is compatible
The following devices can be upgraded to iOS 9: iPhone 5 and above, iPad 3 or later, iPad Mini and above, iPod Touch fifth generation. The iPhone 4s cannot upgrade to iOS 9 although, given the problems iOS 8 caused for iPhone 4s owners, Apple was probably right to leave the phone stuck on iOS 8.
Backing up your devices is always a sensible idea and doing so before a software upgrade especially so.
So make sure you put your most precious documents and photos in your cloud platform of choice, or plug into your laptop and upload it all to the hard drive. This should mean that, if the worst happens, your most important data is still safe.
Check your storage
Updating to iOS 9 will require a lot of storage. If you’re already on iOS 9, 9.0.1 or 9.0.2 it will be as much as 2.2GB and if you’re still on iOS 8 it will be even more. It's a good idea to check this before you start. If you've moved to iOS 9.1 but have yet to install iOS 9.1.1 or 9.1.2 the update size is much smaller.
With iOS 9.1.3 Apple has tried to reduce the space required to update to the newest version of iOS 9. This means that the move to iOS 9.3 is 223MB for those on the most up-to-date versions of iOS 9.
You can find out how much storage you have by going to Settings > General > Usage. The ‘Manage Storage’ button will let you see which apps and services are taking up the most room.
This is a good way of doing some housekeeping by removing apps you never use or trimming the number of photos and videos stored on your device.
Over the air
If you're carrying out the update 'over the air', make sure you're on a good, stable WiFi connection and the phone or tablet has plenty of battery. To download in this way, simply go to Settings > General > Software Update and wait for the update screen to appear.
When you can always use iTunes to download iOS 9. Yes it’s not the nicest software to look at and updating over WiFi is quicker and easier, but using iTunes dramatically reduces the amount of storage required for the update.
Make sure you have the latest version of iTunes installed and that your laptop has enough battery so it won’t conk out half way through the update.
Why you should update
Updating devices can be time-consuming and a chore but it’s a good habit to get into as it should mean you’re fully protected from any software security holes as the most recent version will have all the necessary fixes.
The iOS 9 update contains many fixes related to security and more general stability issues such as video crashes and orientation problems. The move to iOS 9 is recommended if your handset suffers from any of these problems.
