How to Clear Cache on iPhone

Is your iPhonerunning slow? Maybe websites take too long to load, or apps feel sluggish. A full cache might be the problem. Your iPhone stores temporary data to help apps and websites run faster, but this cache can build up over time.

Clearing your iPhone’s cache can free up storage space and often fixperformance issues.You can clear Safari’s cache by going to Settings > Safari > Clear History and Website Data. For other apps, you’ll either need to use their built-in options or delete and reinstall them.

Regular cache clearing isgood phone care. Many users notice better performance right away. It’s a simple fix that costs nothing but can make your iPhone feel new again.

Here’s the latest and most complete guide based on everything up to 2025:

Clearing the cache on your iPhone can help free up storage, improve app performance, and fix random glitches. However, unlike computers, the iPhone doesn’t have a universal “clear all cache” button — you need to clear it individually for apps, browsers, and system processes. Here’s how to do it effectively:

1. Clear Safari Cache

Safari is often the biggest culprit when it comes to cached files.

This removes cookies, browsing history, and cached images, which can make Safari snappier and free up space.

Important:If you want to keep your browsing history but still clear cache, you’ll need to go intoAdvanced>Website Data>Remove All Website Datainstead.

2. Clear App Cache (Per App)

Most third-party apps (like Instagram, TikTok, and YouTube) build up their own cache over time. iOS still doesn’t have a “clear cache” button for all apps, but you can manually clear it in a few ways:

Check App Settings

Some apps have their own cache clearing options inside the app settings. For example:

Always check individual app settings first.

Offload and Reinstall Apps

If an app is bloated and has no built-in clear cache option:

This method often clears out old cached files that clog up space.

3. Clear Messages and Media Caches

Messages (especially with lots of photos, videos, and GIFs) can build up serious cache data.

This can free up several gigabytes without losing important conversations.

4. Restart Your iPhone

After clearing caches,restart your iPhoneto fully clear out temporary system cache files. This forces iOS to rebuild system caches more efficiently.

Restarting after cache clearing is one of the easiest tricks to speed up an older iPhone.

5. Use “iPhone Storage” Smart Recommendations

As of iOS 17 and iOS 18, Apple gives personalized cache-clearing suggestions:

Apple’s built-in suggestions can quickly eliminate gigabytes of junk you may not even realize is stored.

Key Takeaways

Understanding Cache on iPhone

Cache files build up on your iPhone as you use apps and browse the web. These temporary files store data to help your phone run faster, but over time they can take up space and slow things down.

What Is Cache?

Cache is a collection of temporary files stored on your iPhone. These files help your device load information faster when you revisit websites or reopen apps.

When you browse websites, your iPhone saves images, scripts, and other data. This means your phone doesn’t need to download the same content every time you visit a site.

The same happens with apps. They store data locally to improve loading times and performance. While this is helpful, cache files can pile up quickly.

Think of cache like a notebook where your phone jots down things it might need later. This system saves time, but the notebook gets full eventually.

Types of Cache

iPhones have several types of cache that build up in different ways:

Browser Cache: Safaristores website dataincluding images, scripts, and login information. This helps websites load faster on repeat visits.

App Cache: Each app keeps its own set of temporary files. These can include:

System Cache: iOS itself creates cache files for smoother operation. These files help your iPhone run more efficiently.

Social media apps are often the biggest cache culprits. Apps like Instagram, TikTok, and Facebook can store hundreds of MB or even GB of cached videos and images.

Benefits of Clearing Cache

Clearing your iPhone’s cache offers several important advantages:

Frees up storage space– Removing cache can recover significant storage, especially if you haven’t cleared it in months. Apps like Safari and social media platforms can accumulate hundreds of MBs of cache.

Improves performance– A cluttered cache can slow down your iPhone.Clearing these temporary filesoften makes apps and websites run more smoothly.

Fixes app problems– When apps misbehave, clearing their cache can solve many common issues. It’s often the first troubleshooting step recommended by app developers.

Enhances privacy– Cache files can contain personal information from websites and apps. Clearing them helps protect your privacy, especially on shared devices.

Many iPhone users notice their device feels faster and more responsive after a good cache cleaning session.

Preparing to Clear Cache

Before clearing your iPhone’s cache, take a few key steps to ensure you don’t lose important data. Proper preparation helps you understand what space you’ll free up and protects your personal information.

Backup Important Data

First,back up your iPhonebefore clearing any cache. This prevents accidental data loss during the process.

Tocreate a backup:

You can also back up through iTunes or Finder on a computer. This creates a safety net in case something goes wrong.

For apps with important data, check if they have their own backup options. Some apps store data in the cache that might be useful later.

Take screenshots of any settings you’ve customized. This makes it easier to restore your preferences after clearing cache data.

Understanding Storage Usage

Check your current storage situation before clearing cache. This helps you know what to expect.

To view storage:

Look for apps with largeDocuments & Datasections compared to their actual size. These are prime candidates for cache clearing.

Some apps like Safari, social media, and streaming services typically build up large caches. TheiPhone Storage screenoffers recommendations to optimize storage at the top of the page.

How to Clear Safari Cache

Safari stores temporary files that can slow down your iPhone over time. Regular cache clearing helps improve performance and protects your privacy.

Clearing Cache and Cookies

You can quickly remove stored website data in Safari through your iPhone settings. Toclear cache, go to Settings, scroll down to Safari, then tap “Clear History and Website Data” at the bottom of the screen. This removes browsing history, cookies, and other browsing data.

For more targeted cleaning, you canremove specific website data. Go to Settings > Safari > Advanced > Website Data. Here you’ll see a list of all websites storing data on your device. You can remove individual sites or tap “Remove All Website Data” to clear everything.

This process helps fixslow loading timesandbrowsing problems. After clearing cache, websites might load slower initially as Safari rebuilds temporary files.

Deleting Browsing History

Safari keeps track of websites you visit, which might concern privacy-conscious users. To delete your browsing history, open the Safari app and tap the bookmarks icon at the bottom of the screen.

Next, tap theclock icon for History. At the bottom of this screen, tap “Clear” and choose how far back you want to erase:

you’re able to alsoclose tabs when clearing historyby checking that option before confirming. This gives you a fresh start with no open pages.

Clearing Cache in Other Browsers

While Safari is the default browser on iPhones, many users prefer Chrome or Firefox. Clearing cache in these browsers follows different steps but is just as important for maintaining privacy and phone performance.

To clear cache in Chrome on your iPhone, start by opening the app. Tap the three dots in the bottom right corner to access the menu. SelectSettingsfrom the options that appear.

In the Settings menu, tap onPrivacy and Security. This section contains all theprivacy-related optionsfor Chrome.

Next, selectClear Browsing Data. Chrome will show several options you’re able to clear:

You can select which items to remove by checking the boxes. For cache clearing, ensure “Cached Images and Files” is checked.

Choose the time range from the dropdown menu at the top. Options typically include:

TapClear Browsing Datato complete the process.

Firefox users can clear cache through a similar process. First, open Firefox on your iPhone and tap the three lines (hamburger menu) in the bottom right corner.

SelectSettingsfrom the menu that appears. This takes you to the browser’s settings page where all customization options are listed.

Scroll down and tapData Management. This section controls how Firefox handles your personal data and browsing information.

Under Data Management, you’ll find the option toClear Private Data. Tap this to see what you’re able to remove:

Check the boxes for the data you want to clear. Make sure “Cache” is selected to remove stored website data.

TapClear Private Dataand confirm your choice when prompted. Firefox will remove all selected items immediately.

After clearing cache, Firefox may need to rebuild some data when you visit websites again. This might make initial page loads slightly slower.

Managing Cache on Apps

iPhone apps store temporary data as cache to run faster. This data can build up over time, taking up storage space and sometimes causing apps to slow down.

Clearing App Cache

Some iPhone apps have built-in options to clear their cache. To check if an app has this feature, go to Settings and scroll down to find the app you want to manage. Tap on it and look for cache clearing options in the app’s settings page.

For Safari, clearing cache is straightforward.Open Safari settingsby going to the Settings app, scrolling down to Safari, and tapping “Clear History and Website Data.” This removes browsing history, cookies, and other browsing data.

Many apps don’t offer direct cache clearing options. In these cases, users can try alternative methods:

Offloading Unused Apps

When iPhone storage runs low, offloading apps can help free up space while keeping app data intact. This is different from deleting apps completely.

To offload an app manually:

The app icon stays on your home screen with a small cloud symbol. When you tap it again, the app will download automatically if you’re connected to the internet.

you may also set up automatic offloading by going to Settings > App Store > Offload Unused Apps. Your iPhone will then automaticallyoffload appsyou rarely use when storage space is needed.

Optimizing iPhone Storage

Freeing up space on your iPhone helps it run faster and makes room for new apps and media. Let’s look at how to check what’s using your storage andremove filesyou don’t need anymore.

Reviewing Storage Recommendations

The iPhone offers built-in suggestions to help manage your storage. To find these tips, go toSettings > General >iPhone Storage. At the top, you’ll see a color-coded bar showing how your storage is being used.

Below this bar, iOS displays personalized recommendations to free up space. These might include:

The recommendations are based on your actual usage patterns. Tap any suggestion to learn more or enable it right away.

Your iPhone also shows how much space each app uses. Apps are listed from largest to smallest, making it easy to spot storage hogs.

Deleting Unnecessary Files

Start by removingcached images and junk filesthat accumulate over time. For Safari, go toSettings > Safari > Clear History and Website Data.

For other apps with large caches:

Photos and videos often take up the most space. Consider:

Apps you rarely use can be offloaded or deleted completely to free up space.
