Key takeaways from ZDNET

I think yours is iPhone There are dozens of applications running and perhaps several browsers each with lots of tabs open at all times. I know mine is. The problem is that all this activity causes cached data to accumulate over time.

Whenever you use apps or browsers on your phone, they store some information locally, such as images, scripts, and login information, to make your iPhone perform faster. Websites load faster and apps appear faster. At least that’s how it’s supposed to work in theory.

But, like a junk drawer that starts out as a handy place to stash odds and ends like a screwdriver, sticky notes, or a spare battery so you can grab them and get things done quickly, the cached data eventually overflows, making quick work impossible.

Clearing your cache is like cleaning out that drawer. Suddenly everything works as it should. Your phone is lighter and runs smoother. So let’s look at every way to clear the cache of a working iPhone iOS 26and why you should make it a habit?

How to clear iPhone cache

What you will need: When prompted, you’ll need an iPhone running iOS 26 and your Apple ID password or device passcode.

1. Clear Safari history and website data on iPhone Or just remove all website data

If your main browser is Safari, you should know that every time you use it, every site you visit saves temporary files on your device to help pages load faster the next time you browse. However, over time, these files can accumulate and cause Safari to slow down or have difficulty performing simple tasks.

Here’s how you can fix this by clearing the cache.

2. Scroll to Safari and tap it.

3. Find and tap Clear History and Website Data.

4. Choose a time frame (I recommend All History).

5. Tap Clear History to clear your history, cookies, and cache.

You can clear Safari’s history and website data directly in the app, but you’ll find more options in Settings. Doing this regularly can fix errors or speed up browsing without deleting your bookmarks or saved passwords.

Moreover: I found an iPhone and Mac browser that’s faster, safer, and easier than Safari

Tip: For even more granular control, go to Settings > Apps > Safari > Advanced > Website Data, then tap Remove All Website Data. This will only clear cookies and tracking data, not your browsing history. Safari will act as if you haven’t visited any sites before, so you’ll have to sign in to your favorite services again.

2. Clear Chrome browsing data on iPhone, including cached images and files, cookies and more

If you use Chrome on your iPhone instead, you can clear the cache just like you can with Safari. Chrome also saves temporary data to improve speed, but these files can still overflow, bloat, and become buggy.

Chrome has a variety of cache controls built right into the app, so there’s no need to delve into Settings this time.

1. Open the Chrome app on your iPhone.

2. Tap the three-dot menu in the right corner.

3. Select Settings > Privacy & Security > Clear Browsing Data.

4. Choose a time period (I recommend All Time).

5. Make sure Cached Images and Files is checked. You can also add Cookies, Site Data and Browsing History for a deeper clean.

Clearing Chrome’s cache forces sites to reload from a clean page; This can help fix slow or faulty browsing sessions. If you also clear your cookies in Safari, you may be logged out of some services, but your bookmarks and passwords will remain unchanged.

3. Offload or delete unused apps on iPhone Try social media, games and streaming apps

Most apps don’t have a dedicated “clear cache” button to remove temporary files and free up space, but iOS 26 allows you to offload or delete apps, which effectively clears the built-in cache and helps you manage your storage.

1. Open Settings > General > iPhone Storage.

2. Check out the list of apps sorted by size.

3. Tap an app to view its details.

4. Select Offload App to remove the app but keep its data, or Delete App to remove everything.

5. Reinstall it from the App Store later if necessary.

Social, streaming and gaming apps often accumulate gigabytes of cache. Emptying or deleting them can free up a significant amount of space. For example, YouTube Kids had 5.5GB of stored data on my device.

Moreover: Low on iPhone storage? Do this instead of deleting your apps

Tip: To let iOS 26 remove apps you rarely use, you can turn on Offload Unused Apps under Settings > App Store.

4. Restart your iPhone Flush temporary system files and refresh memory

After clearing the browser and app cache, it’s time to restart your iPhone. iOS 26 also stores hidden system cache and temporary files in the background, but restarting clears this and can refresh memory and performance.

1. Press and hold the Power and Volume Up buttons until the slider appears.

2. Slide to Turn Off Your iPhone.

3. Press the Power button to turn it back on.

If your buttons aren’t working, go to Settings > General > Turn Off.

Moreover: Restarting your phone every day is your best defense against zero-click attacks

A quick restart can make your iPhone feel faster, fix background problems, and even improve security.

FAQ

What is my iPhone’s cache?

Cache is a collection of temporary files that apps and websites store locally on your device to speed up loading, browsing, and your overall session. For example, Safari saves images or scripts from sites so they don’t need to be re-downloaded. It’s useful, but too much cache can slow down your iPhone; Therefore, cleaning it regularly ensures trouble-free performance.

Moreover: Cookie pop-ups don’t have to be a fact of online life – how and why I block them

Clearing the cache only removes temporary data, not your bookmarks, messages, photos or passwords. Offloading an app also preserves your data and settings if you want to reinstall it later, but deleting an app deletes everything for a full reset.

Is caching the same as cookies?

Cache and cookies are not the same. The cache stores copies of images, scripts, and other elements so websites load faster next time. Cookies save personal data such as login information, preferences and shopping cart items. Clearing the cache removes saved page files, while deleting cookies deletes your login information and settings and requires you to log in and reconfigure preferences.

How often should I clear my iPhone’s cache?

It depends, but it’s a good habit to clear your browser cache once a month and restart your iPhone every day or at least once a week. You should also regularly install or delete apps you don’t use, especially if they take up too much space or cause problems.

Can I clear cache in other browsers or apps?

Yes. Browsers like: firefox And Edge It has its own cache clearing options. However, in my experience, many applications do not allow you to manage cache. Some of the more popular ones are: tiktok And on SnapchatYou can find this directly in the settings.
