If your iPhone feels sluggish or storage is maxed out, clearing the cache can make a noticeable difference. This is the proper method to follow.
iPhones are powerful devices, but even the best ones need a performance tune-up from time to time. One of the most effective ways to give your iPhone a speed and storage boost is by clearing its cache.
Cache refers to temporary data stored by apps and browsers to improve speed and user experience. Over time, however, these files can pile up, leading to lag, unresponsive apps, or storage warnings.
Here's a practical, expert-backed guide on how to clear the cache on your iPhone—without compromising essential data.
Why Clearing Cache Matters On iPhone
Clearing cache can help you:
- Reduce performance issues
- Free up storage space
- Prevent app crashes and lag
- Fix battery drain
- Improve browsing and app experience
Clear Safari Cache In Under 30 Seconds
Safari, Apple’s built-in browser, stores cached files from websites. Here’s how to remove them:
- Open Settings
- Scroll and tap Safari
- Tap Clear History and Website Data
- Confirm when prompted
Note: This logs you out of most websites and deletes cookies, but it won't delete bookmarks or saved passwords.
Clear App Cache On iPhone: What You Can And Can’t Do
Unlike Android, iPhones don’t have a one-tap app cache clearing feature. But two simple options work well:
1. Offload Unused Apps
This deletes the app but keeps its documents and settings.
- Go to Settings > General > iPhone Storage
- Tap any app
- Tap Offload App
2. Delete and Reinstall Apps
This method removes the app and all of its cached data.
- Press and hold the app icon
- Tap Remove App > Delete App
- Reinstall it from the App Store
Recommended for heavy apps like Facebook, TikTok, Instagram, and Snapchat.
Clear Cache in Chrome, Firefox, and Other Browsers
If you’re using a browser other than Safari:
- Open the browser
- Tap the menu (three dots or lines)
- Tap History > Clear Browsing Data
- Select Cached Images and Files
- Tap Clear Data
This helps free up space and fixes slow-loading pages.
Clear System Cache On iPhone (Hidden Files)
There’s no direct button to clear system cache on iPhone, but here are two proven ways to reduce it:
Restart Your iPhone
Restarting your device helps wipe temporary data and gives the memory a fresh start.
Force Restart (Hard Reset)
- Press and release Volume Up
- Press and release Volume Down
- Keep the Side button pressed until the Apple logo becomes visible on your screen.
This is especially useful when your device is frozen or acting up.
Check Which Apps Are Taking Up Space
Check which applications are consuming the largest portion of your storage:
- Go to Settings > General > iPhone Storage
- Wait for the list to load
- Review the app sizes
- Offload or delete based on usage
Use Cleaner Apps (Optional)
Though optional, reliable third-party tools can assist in managing and clearing cached data:
- Cleaner Pro
- Phone Cleaner for iPhone
- Boost Cleaner
Always check reviews and privacy permissions before using third-party tools.

Final Thoughts
Clearing your iPhone’s cache is a quick, safe, and effective way to improve performance, fix app issues, and free up space. Make it a monthly habit—especially if your phone feels slow, gets warm, or runs out of storage often.
By removing browser data, offloading or reinstalling heavy apps, and restarting your device, you can give your iPhone a clean slate without losing important data.
