iPhone feeling sluggish? Clear your cache to speed it up - here's how

May, 23, 2025 Hi-network.com
How to clear iPhone cache

It's easy to overlook a simple habit that can give your iPhone a real performance boost: clearing browser cache. 

Cache is the temporary storage of files -- like images, scripts,andcookies -- that apps and websites save to help them load faster. Over time, those files pile up in your browser, eating into your phone storage and slowing everything down. A quick cache clear is all it takes to free up space, speed up page loads, and even resolve occasional glitches. And it only takes a couple of taps. 

Small habits like this add up to a noticeably smoother iPhone experience.

After all, we spend more than five hours a day on our smartphones. That's more than five hours of your phone accessing, retrieving, and saving cache and cookies, which can negatively impact your iPhone's storage space.

How to clear the cache from Safari on your iPhone

What you'll need:Everything you need to clear your cache is in the Settings app or browser, so grab your iPhone to get started. 

1. Go to your iPhone's Settings app

To delete cached data in Safari, start by opening the Settings app on your iPhone. You can also clear it right from within Safari, but using Settings gives you more options.

4. Confirm you want to clear the browser cache

A popup will appear asking you to choose a "Clear timeframe" (for example, the last hour, today, or "All History" if you want to wipe everything). Once you've made your selection, tap Clear History to remove Safari's cache, cookies, and stored website data. This will log you out of any sites but leave your autofill information intact. 

You'll be prompted to either close all your open tabs or keep them open the next time you launch Safari, a handy option that's only recently become available.

How to clear the cache from Chrome on your iPhone

What is cache?

Cache -- or browser cache -- is the temporary storage of website files. So, things like images, scripts, and cookies that your browser saves on your phone to make pages load faster the next time you visit.

Over time, though, those files can add up, taking a large bite out of your device storage and slowing things down. That's why it's smart to clear your browser cache regularly. In this article, I focused on clearing Safari and Chrome's cache on an iPhone, but keep in mind that apps and even your phone's processor have their own caches, too.

How to clear your app cache on iPhone

You can clear an app's cache by deleting and reinstalling it -- or, when available, using an in-app "Clear Cache" option. Since iOS doesn't offer a universal cache-clearing tool, each app handles it differently. TikTok and CapCut include a built-in cache-clear button, Amazon lets you erase your browsing history, and Reddit offers a way to wipe local history. It depends on an app's features.

Is 'clear cache' the same as offloading?

Not quite. Offloading an app via your iPhone's settings can boost performance when your storage is tight by uninstalling the app and keeping its documents and data intact. Just go to Settings > General > iPhone Storage, tap the app you want, and choose Offload App. This removes the app and its cache but leaves your data in place, so when you reinstall it, you'll pick up right where you

Are cookies and cache the same thing?

Cache and cookies are not the same. 

Cache stores copies of images, scripts, and other page elements so sites load faster on your next visit, while cookies are small data files that remember specific information about you -- like login credentials, site preferences, or items in your shopping cart.

Clearing your cache removes those saved page files but won't log you out of sites, whereas deleting cookies will wipe your saved logins and settings, forcing you to sign in again and reset any preferences.

Can you block cookies on an iPhone?

You can block cookies in Safari. Turning them off stops sites from tracking you, but it can also break some websites or limit features. So, you'll need to weigh privacy against usability. If you'd like to block cookies in Safari, follow these steps:

  1. Go to Settings and select Safari.
  2. Tap on the toggle next to Block All Cookies.

There are also third-party extensions -- such asGhostery and Disconnect -- that help you block cookies and trackers in Chrome.

How to check your iPhone's storage

Your iPhone's Settings can show you what's eating up your storage, whether it's photos, videos, music, or even an app's temporary data. To see a full breakdown of your storage usage, follow these steps:

  1. Go to the iPhone's Settings.
  2. Tap on General.
  3. Select iPhone Storage.
  4. Scroll through to find the app you're looking for.
  5. Tap on the app to view storage status and options.

Unfortunately, you can't clear a third-party app's cache directly in Settings, but this view gives you a clear breakdown of your storage and lets you delete or offload apps.

How to browse on Safari without creating a history

If you're learning how to clear the cache on an iPhone, you might wonder if there's a way to use Safari without saving any browsing history. Yes! You can turn on Private Browsing by following these steps:

  1. Open Safari.
  2. Tap on Tabs.
  3. Choose Private.

You can also enable Private Browsing by going to your iPhone Settings, finding Safari, and toggling on the private option.
