How to Clear Cache on iPhone
Learn how to clear cache on iPhone in Safari, reduce app storage, clear website data, fix slow browsing, avoid mistakes, and answer FAQs.
Quick Answer
To clear cache on iPhone, clear Safari history and website data from Safari or Settings, remove website data for specific sites if needed, restart the iPhone, and offload or reinstall apps that use too much storage. Back up important app data before deleting anything.
What You Need
- iPhone
- iOS Settings access
- Safari app
- Apple Account password optional
- Wi-Fi optional
- Recent backup recommended
Safety Precautions
- Clearing Safari data can sign you out of websites.
- Do not delete an app unless you know whether its data is backed up or stored online.
- Avoid third-party cleaner apps that request unnecessary access.
- If the iPhone is managed by work or school, some settings may be restricted.
Step-by-Step Instructions
- Step 1
Clear Safari history
Open Safari, go to history options, choose Clear, and select the timeframe you want to remove.
- Step 2
Clear website data in Settings
Use Settings > Apps > Safari or Settings > Safari, depending on iOS version, to remove history and website data.
- Step 3
Remove data for one site
Use advanced website data options if you only want to remove storage for a specific website.
- Step 4
Restart iPhone
Restarting can clear temporary behavior after cache changes.
- Step 5
Review app storage
Go to iPhone Storage and identify apps using unusually large space.
- Step 6
Offload or reinstall apps
Offload apps to keep documents when available, or delete and reinstall only if data is safe.
- Step 7
Test the issue
Reopen Safari or the app and check whether speed, login, or display problems improved.
Practical Example
Example: Safari keeps loading an old version of a website. You clear Safari history for the last hour, reopen the site, and it loads the current page.
Common Mistakes
- Deleting apps without backup
- Expecting one cache button for every app
- Using risky cleaner apps
- Clearing all history when only one site is the problem
- Forgetting saved logins may be affected
Troubleshooting
Website still looks wrong
Clear that site data, close Safari tabs, restart iPhone, and try again.
App cache is huge
Check whether the app has its own clear-cache setting, then offload or reinstall if data is backed up.
Storage is still full
Review photos, videos, messages, downloads, and offline media, not only cache.
Clear option is unavailable
Check Screen Time restrictions, managed-device settings, or iCloud/Safari sync behavior.
