I’m sure this sounds familiar: You’re trying to install the latest iOS release, upgrade to a new iPhone, or just download that cool app everyone’s talking about, and your iPhone says the storage is full.
You’ve already deleted every app you don’t think you need, and there’s still not enough space on your iPhone. So you open Settings, tap General, then iPhone Storage, and, sure enough, your iPhone is full. Worst of all, a huge chunk of it is just listed as “Other.” What’s that supposed to mean? How do you get rid of it? The Other storage section is mysterious and confusing, and there’s no one answer that works for everyone, but hopefully, this guide will help you deal with this problem.
Latest iPhone release: iPhone SE (2022), iPhone 14, iPhone 14 Plus, iPhone 14 Pro, iPhone 14 Pro Max (2022)
Latest iOS release: iOS 16.2 (December 2022)
Latest iOS beta: iOS 16.3
How to view your iPhone storage
To see how much storage all your apps and data are taking up on your iPhone’s storage, open the Settings app, select General, then iPhone Storage. At the top, you’ll see a bar graph showing your total iPhone storage and which types of data are filling it up. Beneath that you’ll find a list of applications on your phone and how much room they take up, both for the app itself and its stored data.
It may take several seconds for your iPhone to show the graph, as it takes time to scan and analyze its storage. Even after the chart first appears, you’ll want to wait several seconds more for it to stabilize, as the app list and storage sizes can change while your phone completes its analysis.
What is Other storage, anyway?
Your iPhone Storage menu will divide that bar up top into familiar categories like Apps, Media, Photos, and Mail, but also an “Other” category that is sometimes very large. It’s common for Other to be in the 5-20GB range, but if it’s way over 20GB, it has probably grown out of control. You can scroll all the way down to the bottom of the app list where you will see “iOS” and “System Data” listed. Tap on “System Data” to see how much “Other System Data” is taking up.
The Other category is big and varied because it’s a real catch-all category. It’s comprised of system caches, logs, Siri voices (if you’ve downloaded more than one), updates, and so much more. One of the biggest culprits for Other growing out of hand is streaming lots of music and video. When you download video or music from the iTunes store, TV app, or Music app, it’s indexed as Media. But streams have caches used to ensure smooth playback, and those are categorized as Other. We discuss how to delete Other storage on a Mac in a separate article.
Safari’s caches can start to grow pretty large, too. And if you send tons of texts with images or video, the caches for that can start to fill up a lot of space. Your iPhone is supposed to manage these caches to keep your storage from becoming completely full, but it doesn’t always do a great job.
How to reduce the size of Other data
You can’t get rid of Other entirely, but you can sometimes reduce its size.
First, let’s try clearing your Safari caches. Open Settings > Safari and choose Clear History and Website Data. If you have a lot of Safari tabs open on your iPhone, you might want to close most of them, too.
You might also want to change Messages to save fewer old messages. Open Settings, then Messages, and scroll down to the Message History setting. By default, Keep Messages is set to Forever, but you may want to change it to 1 Year or even 30 Days to reduce the data that the Messages app caches.
Finally, go back to iPhone Storage and look at the apps list. Most of the apps store data that is categorized as Apps, but some will keep caches that are categorized as Other. If, say, the Podcasts app is taking up a couple of gigabytes of space, it’s likely mostly cached data. Deleting the app and re-downloading it might put a dent in the Other category.
The nuclear option: Backup and Reset with iTunes
You can go through your iPhone trying to delete every little cache that could grow the size of Other storage, but if you really want to make it as small as possible, you need to back up your phone and reset it. This can take a little while. The best way to do this is to use your Mac or PC.
First, connect your iPhone to your Mac with the bundled USB-C-to-Lightning cable.
When prompted on your iPhone, tap “Trust” and enter your passcode.
In the Finder sidebar on your Mac, select your iPhone under Locations.
Click the General tab.
Select “Back up all of the data on your iPhone to this Mac.”
To encrypt your backup data and protect it with a password, check the “Encrypt local backup” box.
Click Back Up Now.
Note: You can also connect your iPhone to your computer wirelessly if you set up syncing over Wi-Fi.
On a PC or a Mac with macOS 10.14 or later is earlier, you can use iTunes to back up your phone. After you connect your iPhone to your Mac or PC, select your iPhone by clicking the little phone icon in the upper left, and under Backups, choose “This Computer” and check the “Encrypt local backup” box to protect your backup with a password. Then click the button to Back up now.
When the backup is done, disconnect your iPhone and head to Settings > General > Reset and choose Erase All Content and Settings. This will return your iPhone to an out-of-the-box state. When it restarts and it’s in the initial setup process, re-connect it to your computer with iTunes open, and follow the instructions on the screen to restore your device.
This is the longest and most involved way to reduce the size of Other storage, but it’s also the best; there’s just no way to get it any smaller than it will be after a fresh reset and restore.
