How to Clear iPhone/iPad System Data in 2023 (6 Methods)

While taking a close look at the breakdown of the storage consumption, have you ever wondered what is the System Data (formerly called Other data) on iPhones and iPads and how to clear it to recover your precious storage? If the answer is yes, you are not alone to have hit this path and got taken aback to figure out how much space this mysterious section has hacked on your iOS device. Whether you are on a cleanup drive to declutter your iPhone or eager to sort out this riddle for good, let me show you how to clear System Data storage on iPhone/iPad with ease.

Note: It’s worth noting that System Data was previously called Other Data. People using iOS 14 or earlier can still find the previous name. If you are one of them, you can check out our detailed guide on how to clear other data on iPhone. However, people using iOS 16 should keep following the steps below.

1. Clear App Cache

It’s recommended to clear the cache of apps from time to time. Else, the huge pileup of cached data starts creating problems like random crashing, freezing, unexpected sluggishness, and even draining more battery. Fortunately, some apps let you delete the cache right from inside their settings. All you need to do is head on over to an app and check out its settings for the option to clear the cache. However, there are apps that don’t offer a direct way to clear cache on an iPhone or iPad. In such cases, you either have to offload an app or delete it completely. When you offload an app, it will delete the app but keeps its documents and data intact.

In the screenshot below, you can see the option to delete the cache of the Spotify app under the Storage section. This way, you can save space on your device.

If you’re still not able to clear out enough space on your iPhone, you can offload apps to free up some additional storage. With iOS 16, the unused apps get offloaded automatically once the option is enabled. For this, open Settings -> General -> iPhone Storage and enable Offload Unused Apps.

To stop offloading apps, you can to Settings -> App Store -> disable the Offload Unused Apps option. In addition to this, you can choose to delete or reinstall existing apps, which can help in clearing some space for you.

2. Clear Browsing History and Website Data

Another reliable way to prevent the System Data from capturing a lot of unnecessary storage is to delete the browsing history and website data on a regular basis. Though saved history makes it more convenient to access frequently-visited websites and saves you time, you shouldn’t keep the website history for far too long.

Personally, I prefer to get rid of the browsing history every once in a while. It not only lets me keep the browser clutter-free but also safeguards my privacy. Besides, it also plays a vital role in helping the browser run smoothly. Clearing the browsing history of all the popular web browsers such as Safari, Chrome, and Firefox is pretty easy. Let me show you how it’s done:

Clear Safari Browsing History

If you want to clean up Safari caches, open Settings -> Safari -> Clear History and Website Data. Tap Clear History and Data to confirm your decision.

Clear Chrome Browsing History

Open the Chrome app, tap on the three-dot icon from the bottom and choose History. Then, tap on Clear Browsing Data. After that, choose the time range and hit Clear Browsing Data again.

Clear Firefox Browsing History

Launch the app, tap on the menu button (three tiny horizontal lines) and choose History. Following this, tap the Delete icon present at the bottom-left and then choose Everything in the menu to wipe out the entire history.

3. Delete Large Message Attachments

It’s always good to remove the message attachments that are no longer required so that they don’t end up occupying the iPhone or iPad’s storage. Apple’s Message app provides a simple way to keep track of message attachments and remove them with ease. Here’s what to do:

1. Go to Settings -> General -> iPhone/iPad Storage.

2. Tap Messages. Under the Documents section, you should see different categories like Top Conversations, Photos, and Videos. Now, head into the respective category and then delete the useless attachments.

For those who don’t know, WhatsApp has a similar way of managing media and deleting unnecessary files to save up storage. You can follow our guide on how to manage storage on WhatsApp to further free up your device’s space.

4. Reduce Message History

Apart from getting rid of the unnecessary message attachments, you can also choose to remove the history of the text messages from time to time, so that you are able to maintain your iPhone or iPad’s space. Here’s how to do it:

1. Navigate to Settings -> Messages and select the Keep Messages option.

2. From there, choose to go for 30 days or 1 year instead of Forever. You will now be prompted with an option to delete older messages. If you are okay with this, go ahead and make the changes. This way, you can delete your message frequently.

5. Update Software

Not too long ago, iOS/iPadOS 13 faced one rare issue that prevented the system from freeing up storage on iPhone and iPad. The problem was so rampant that Apple had to release a software update to fix the issue. So, if your device storage is full and it’s mostly consumed by System Data, try updating the software.

1. Head to Settings -> General and select the Software Update option.

2. If available, download and install the latest iOS/iPadOS updates.


6. Restore Your Device As New

If the aforementioned steps haven’t really helped, I would recommend you restore your device as new. While it’s a big step for deleting the System Data on iPhone and iPad, it’s the way to go, especially when you want to have a clean slate. But before trying out this method, make sure to back up your device via iCloud or iTunes. Once done, follow the steps below:

1. Go to Settings > General > Transfer or Reset.

2. Then, choose Erase all content and settings and tap Continue.

3. If prompted, enter your device’s passcode. Your iPhone will upload your data to iCloud backup. You can also choose to skip it.

4. Next up, enter your Apple ID Password and tap Turn Off from the top-right corner. Finally, hit the Erase iPhone option.

5. Once you’ve reset your iPhone, follow the set-up assistant to set up the device.

Alternatively, you can use iTunes to restore your device. Simply, connect your iPhone to a computer and launch iTunes (macOS Mojave or earlier or Windows)/Finder (macOS Catalina or later). Now, select your device and then hit Restore iPhone/iPad. After that, follow the prompts to complete the process.

What is System Data on iOS and iPadOS?

To make the task of tracking storage consumption on iPhone and iPad a straightforward affair, iOS presents a pretty neat storage section that breaks down the consumption for users to know how much each category (apps, media, photos, iOS, and more) has captured. The colored section of each category can determine the amount of space each one of them has occupied.

If you are wondering what the “System Data” section includes, you should know that it comprises everything that doesn’t fall in the bracket of the predefined categories. According to Apple, the storage category consists of non-removable things such as offline translation languages, fonts, dictionaries, Siri voices, logs, cache, local keychain data, CloudKit Database, and more. Long story short, it’s a cluster of a variety of miscellaneous data that exists on your iOS device.

How to View System Data on iOS and iPadOS

There are two ways to view System Data on your iOS or iPadOS device.

On iPhone or iPad

1. Head to the Settings app, choose General and then tap on iPhone storage to view the breakdown.

Frequently Asked Questions (FAQs)

Is clearing the cache harmful?

Clearing cached data is not harmful. In fact, it allows you to get rid of the “junk” system files that only end up occupying the device’s extra space and slowing it down.

Why does System Data on iPhone keep increasing?

System Data (or Other data) on iPhone can quickly occupy a lot of storage space. While a lot of this is due to things like caching, logs, and temporary file storage, there are other reasons as well. If you watch a lot of streamed video content on your iPhone, that can quickly eat into your iPhone’s storage space as well by adding to System Data.

  • For all the YouTube users, clear your Watch & Search History! I’ve never done it before so I guess it kept filling up space, my system data was at 140 GB and after deleting it it shrank to 7!!

  • My iPad has total 32 gb space but more than 16 gn is taken up by system data….I’m worried I will loose all my data if I reset or disconnect this iCloud from this iPAd…what should I do?

  • My iphone system data is on 50 gb
    Have reset my iphone
    But Still im facing the same problem
    With storage of system data

    • I have exactly the same issue. I have tried everything including reseting, erasing all content and settings two times but still the same problem

  • Your article was extremely helpful. I reset my iPhone after taking back up on the laptop. This helped clear almost 30 GB of system data.

    • I did the same, within 2 weeks all 40GB of system data it cleared, came right back

      • I did the same a few days ago ,already systems data is filling up space ,currently at 9,34 gb

  • i have tried restarting, cleared messages and safari history. saved +10gb. Just what I needed, Thanksss 🖤

  • Restore Your Device As New
    Don’t waste your time. I spent hours trying the other recommendations, to no avail.
    Have always been impressed with Apple vs that other system, having switched completely a number of years ago.
    IMHO, updating OS on top of update after update gets bloated.
    Start fresh, I can’t believe the performance improvement on my 12 Pro.🙌😀

  • Clearing most “system data” is simply done by powering off the iPhone and turning it back on. How my iPhone was using 83GB of storage just by running is beyond me, but it was. Just powering off and on cleared 75GB of it.

    • Absolutely, the power-off and power-on option worked wonders for me. I had initially deleted unnecessary apps and files but still had a whopping 250GB of system data. This occurred after I’d set up a new iPhone 13 Mini with data copied over from an older device. Then, as if by magic, following a restart I was down to a mere 2.97GB of system files. Leaves crash diets for dead.
