When I attempted the upgrade from iOS 7 to iOS 8 on my 16GB iPhone, the upgrade failed because I didn’t have enough free space. I completely reset my phone at that point to allow for the upgrade, losing all my photos and other information. Now I’d like to upgrade from iOS 8 to iOS 9, but I really don’t want to go through this drill again. Is there some way to ensure that I can upgrade without resetting my phone?
It’s true—the upgrade from iOS 7 to iOS 8 required a lot of free space on the phone, and that space is hard to come by on a 16 GB iPhone. Luckily, the upgrade to iOS 9 should require a good deal less space than the upgrade to iOS 8 did, and you may be able to perform the “over the air” upgrade without removing any contents from your phone. A simple alternative, however, is to perform the upgrade via iTunes on your computer. Connect your phone to your computer, fire up the current version of iTunes, and let iTunes download and install the new software. This takes up far less space on the phone, as you don’t need room for the downloaded upgrade in addition to the entire operating system, in that case.On the other hand, if space is that tight on your device, you might want to invest some time in clearing off some real estate. Photos, messages, videos, and other content can take up a lot of space on your phone, and occasionally, it’s best to clear out unwanted items so you have room for the latest photos of your cats. You can find many techniques for clearing space on your phone (one of our favorites is to store your photos with an online service that automatically sweeps new photos to the service’s space, like DropBox, and deletes them from your phone).
