How to Clear Cache on iPhone: Easy Steps to Speed Up Your Phone
Your iPhone stores cache to make apps and websites load faster. But too much cache can slow down your phone. If your iPhone feels slow or apps don’t work well, clearing cache can help. Let’s learn how to clear cache on iPhone step by step.
What Is Cache and Why Should You Clear It on iPhone?
Cache is temporary data that helps apps and websites load quickly. But over time, this data takes up space and slows down your phone. Clearing cache removes old files and helps your iPhone run better.
When you clear cache, your iPhone gets more free space. It also fixes problems like apps crashing or web pages not loading. Clearing cache does not delete important files, so it is safe to do.
You should clear cache regularly to keep your iPhone running smoothly. It is especially helpful if your phone is slow or has little storage left.
How to Clear Safari Cache on iPhone for Faster Browsing
Safari saves cache to load websites quickly. But too much cache can slow it down. Here’s how to clear it:
- Open Settings on your iPhone.
- Scroll down and tap Safari.
- Tap Clear History and Website Data.
- Confirm by tapping Clear.
This removes browsing history, cookies, and cache. It helps Safari run faster and frees up space. If you don’t want to delete history, use Private Browsing Mode in Safari.
How to Clear App Cache on iPhone Without Deleting Apps

Apps also store cache, making them take up more space. Some apps let you clear cache, but others don’t. Here’s how to do it:
- Open Settings and go to General.
- Tap iPhone Storage and choose an app.
- Tap Offload App to clear cache without losing data.
- Tap Reinstall to use the app again.
This removes extra files but keeps your app data safe. You can also delete and reinstall apps to clear cache completely.
How to Clear System Cache on iPhone for More Storage
Your iPhone’s system also stores cache, which can take up space. While there’s no direct button to clear system cache, you can do this:
- Restart your iPhone – This removes temporary files and refreshes the system.

- Reset Settings – Go to Settings > General > Transfer or Reset iPhone > Reset and tap Reset All Settings. This keeps your data but clears system cache.
These steps help your iPhone run smoother and free up space.

Does Clearing Cache Delete Important Data? Know the Truth
Many people worry that clearing cache will delete their important files. But that’s not true. Cache is temporary data that apps and websites store. Deleting it does not remove your photos, messages, or saved passwords.
