Why Is System Data So High on My iPhone?
As we mentioned before, System Data contains various files of the operating system and apps, such as caches, logs, updates, fonts, offline translation languages, Siri voices, local keychain data, etc.
Over time, this data can accumulate and take up a lot of iPhone storage space. Most of the time, the size of the System Data is around 5 GB to 20 GB. If it's larger than 20 GB, it's time to reduce it.

How to Clear System Data on iPhone
While we can't get rid of System Data from your iPhone, there are a few things we can do to reduce it.
Clear App Cache
The first thing you can do is clear your app's cache, as some apps store temporary files on your iPhone to keep them running fast.
To clear an app's cache files,
- Tap Settings > General > iPhone Storage.
- Tap the app you want to clear, and then tap Offload App. (This will free up storage used by the app, but keep its document and data.)
Delete Unwanted Apps
Deleting an app from your iPhone deletes the app and all its associated data. If an app is useless to you, delete it in no time. Here's how:
- Touch and hold the app you want to delete.
- Tap Remove App.
- Tap Delete App, then tap Delete to confirm your action.
Clear Browser Data and History
If you frequently use a browser on your iPhone, it is recommended to clear its browser data and history. Here's how to clear Safari data and history:
- Open Settings.
- Scroll down your screen to locate Safari, then tap it.
- Tap Clear History and Website Data > Clear History and Data.
- Tap Close Tabs or Keep Tabs according to your needs.
Enable "Offload Unused Apps"
iOS comes with a feature that allows you to automatically remove unused apps. All you need to do is enable it.
- Open Settings > iPhone Storage.
- Under REMMENDATIONs, find Offload Unused Apps.
- Tap Enable.
Delete Messages Attachments
Message attachments can take up a lot of space on your iPhone. It's good to delete the large and old ones from your device. To do so,
- Go to Settings.
- Tap General > iPhone Storage > Messages.
- Under Documents, you should see categories like Top Conversations, Photos, Videos, GIFs, Stickers, etc.
- Tap the category you want to clear, and hit Edit.
- Select the attachments you don't want, then tap the Trash icon in the top right corner.
Reset Network Settings
Another way to reduce iPhone System Data is to reset network settings. The reset process will delete stored Wi-Fi passwords, network-related data, VPN settings, and more, making your System Data storage smaller.
When you update your iOS, it can assist in reducing the size of System Data on your iPhone. During the update process, the system removes unnecessary temporary files, caches, and outdated features. So if it's been a long time since you updated your iOS, go ahead and update it now.
If none of the above methods work for you, reset your iPhone to factory settings. It’s important to note that this will delete all data on your iPhone. Please back up your iPhone before performing the steps below.
- Open the Settings app.
- Tap General > Transfer or Reset iPhone.
- Select Erase All Content and Settings, tap continue, and enter your passcode.
- Tap Erase to confirm.
By following these methods, you can effectively reduce the System Data on your iPhone, freeing up valuable storage space. We hope these tips have helped you create more room on your device.
