How to Clear System Data on iPhone and iPad: 6 Effective Methods

Is your iPhone or iPad running low on storage space? The culprit may be a buildup of system data. While some system data is necessary for your device to function, it can accumulate over time and take up precious storage. Let’s explore what system data is and how you can clear it to free up space on your iOS device.

What is System Data on iOS?

System data (formerly called “Other” data) includes caches, logs, temporary files, and other miscellaneous items that don’t fit into specific categories like apps or photos. While some of this data is essential, it can balloon in size over time.

To view your system data usage:

  1. Go to Settings > General > iPhone/iPad Storage
  2. Scroll down to see the breakdown of storage usage

Now let’s look at methods to reduce system data and reclaim storage space.

Clear App Caches

Many apps store temporary data to load content faster. However, these caches can grow quite large over time.

Step 1: Open the Settings app and go to General > iPhone/iPad Storage.

Step 2: Tap on an app to see its storage usage details.

Step 3: If available, tap “Offload App” to remove the app while keeping its documents and data.

Step 4: For apps without a built-in clear cache option, delete and reinstall the app to start fresh.

Some apps like Spotify allow clearing cache directly:

  1. Open Spotify and go to Settings > Storage
  2. Tap “Clear Cache”

Delete Browsing Data

Web browsers store history, cookies, and other data that can accumulate over time.

For Safari:
Step 1: Go to Settings > Safari
Step 2: Tap “Clear History and Website Data”

For Chrome:
Step 1: Open Chrome and tap the menu icon
Step 2: Go to Settings > Privacy and Security > Clear Browsing Data
Step 3: Select the data types and time range to clear


Remove Large Message Attachments

Messages can store large files and attachments that contribute to system data.

Step 1: Go to Settings > General > iPhone Storage > Messages

Step 2: Review categories like Top Conversations, Photos, and Videos

Step 3: Swipe left on items you want to delete and tap “Delete”


Reduce Message History

Limiting how long messages are stored can prevent buildup of old data.

Step 1: Go to Settings > Messages > Keep Messages

Step 2: Change from “Forever” to 30 Days or 1 Year

Step 3: Confirm to delete older messages when prompted


Update iOS

Software updates can sometimes resolve system data issues.

Step 1: Go to Settings > General > Software Update

Step 2: Download and install any available updates


Restore Device (Last Resort)

If other methods don’t work, restoring your device can give you a clean slate.

Step 1: Back up your device to iCloud or your computer

Step 2: Go to Settings > General > Transfer or Reset iPhone/iPad

Step 3: Tap “Erase All Content and Settings”

Step 4: Follow the setup process to restore from your backup


Regularly clearing unnecessary system data helps keep your iPhone or iPad running smoothly. While some system files are needed, removing excess buildup frees up space for apps, photos, and other content you actually want to store. Try these methods periodically to maintain optimal storage on your iOS device.
