If your iPhone feels slow, keeps showing "Storage Almost Full," or apps are taking up too much space, you may be wondering how to delete junk files, app cache, browsing history, and temporary files. Unlike Android phones, Apple doesn't provide a single "Clear All Cache" button. Instead, you'll need to clean different types of data from various apps and settings.
The good news is that you can safely remove unnecessary data without deleting your important photos, contacts, or documents. In this guide, I'll show you every method to free up storage on your iPhone.
Can You Delete Junk Files on iPhone?
Yes, but it's important to understand how iOS works.
Unlike many Android devices, iPhones don't create a traditional "junk files" folder. Instead, storage is occupied by:
- App cache
- Temporary files
- Safari website data
- Cookies
- Browsing history
- Downloaded files
- Offline videos and music
- Messages and attachments
- Deleted photos waiting in the Recently Deleted folder
Removing these files can free up storage and sometimes improve your iPhone's performance.
Method 1: Clear Safari Browsing History
Safari stores your browsing history, cookies, website data, and cached files to load websites faster. Over time, this data can consume storage.
Steps:
- Open Settings.
- Scroll down and tap Apps.
- Select Safari.
- Tap Clear History and Website Data.
- Confirm your choice.
This removes:
- Browsing history
- Website history
- Cookies
- Cached images
- Temporary website files
Method 2: Delete Website Data Only
If you don't want to remove your complete browsing history, you can delete website data separately.
Steps:
- Open Settings.
- Go to Apps > Safari.
- Tap Advanced.
- Select Website Data.
- Tap Remove All Website Data.
This clears stored website files without affecting everything else.
Method 3: Delete App Cache
Many apps store cache to load content faster.
Examples include:
- Social media apps
- Video streaming apps
- Music apps
- Shopping apps
- Browser apps
Unfortunately, Apple does not provide a universal Clear Cache button for every app.
Instead:
- Open the app.
- Go to Settings.
- Look for:
- Clear Cache
- Storage
- Downloads
- Free Up Space
Some apps offer this feature, while others do not.
Method 4: Remove App Data
Some apps store several gigabytes of downloaded data.
To manage app storage:
- Open Settings.
- Tap General.
- Select iPhone Storage.
- Choose an app.
You'll see options like:
- Offload App
- Delete App
Offload App removes the app but keeps your documents and settings.
Delete App removes everything, including cached data.
Method 5: Delete Temporary Files
iOS automatically deletes many temporary files over time.
However, you can reduce temporary storage by:
- Restarting your iPhone
- Clearing Safari data
- Removing downloaded files
- Deleting unused apps
- Offloading large apps
Method 6: Empty Recently Deleted Folder
Deleted photos and files still occupy storage until permanently removed.
Photos
- Open Photos.
- Tap Albums.
- Open Recently Deleted.
- Tap Delete All.
Files
- Open Files.
- Tap Browse.
- Open Recently Deleted.
- Delete all files.
Method 7: Delete Downloaded Videos & Music
Offline content from streaming apps can use a lot of storage.
Check apps like:
- YouTube Premium
- Netflix
- Spotify
- Apple Music
- Disney+
- Prime Video
Delete downloaded content you no longer need.
Method 8: Clear Watch History
Some apps save your watch history.
Examples include:
- YouTube
- Netflix
- Prime Video
- Apple TV
Open the app's settings and clear your watch history if desired.
Keep in mind that deleting watch history usually does not free a significant amount of storage. It's mainly for privacy and recommendations.
Method 9: Delete Messages and Attachments
Photos and videos received in Messages can consume several gigabytes.
To remove them:
- Open Settings.
- Tap General.
- Select iPhone Storage.
- Open Messages.
- Review large attachments.
- Delete unnecessary videos and photos.
Method 10: Review Large Apps
To identify storage-hungry apps:
- Open Settings.
- Go to General.
- Tap iPhone Storage.
Apps are sorted by size, making it easy to remove or offload the biggest ones.
What About iPhone Cache Cleaner Apps?
Many App Store apps claim they can remove junk files or clean your iPhone.
In reality, iOS security restrictions prevent third-party apps from accessing or deleting cache created by other apps. These apps may help identify large files, duplicate photos, or unused contacts, but they cannot perform a full system cleanup.
Does Clearing Cache Delete My Photos?
No.
Clearing Safari history, website data, or app cache does not delete your:
- Photos
- Videos
- Contacts
- Messages
- Notes
- Documents
However, deleting an app will remove its data unless it is backed up to iCloud or another cloud service.
Tips to Keep Your iPhone Fast
- Keep iOS updated.
- Delete unused apps regularly.
- Empty the Recently Deleted folder.
- Clear Safari history and website data occasionally.
- Remove old downloads.
- Offload apps you rarely use.
- Review storage usage every few weeks.
Final Thoughts
Although iPhones don't include a one-tap "Delete All Junk Files" option, you can still reclaim valuable storage by clearing Safari browsing history, website data, app cache (where supported), downloaded files, temporary data, and unused apps. Regular storage maintenance helps keep your iPhone running smoothly, improves available space, and reduces storage warnings without affecting your important personal data.
By following the methods in this guide, you can safely clean your iPhone and enjoy better performance with more free storage.
