Our iPhones are a big part of our daily lives; with so much information at our fingertips, we're constantly connected and entertained. Whether you spend just a few hours a day on your phone or it's practically your constant companion, keeping it running smoothly is a top priority. 

Knowing how to clear cookies on iPhone quickly and effectively will help boost your device's output and performance. So, if your iPhone feels slow and glitchy, you've landed in the right place. Let's dive in and give your iPhone the refresh it deserves — but first, the basics.

Cache and cookies explained 

Let's start by demystifying the purpose of cache and cookies on an iPhone.Both cache and cookies exist to improve your browsing and app experience. 

Cache is basically temporary storage space for images, scripts, and other resources that help websites and apps load faster on your next visit, all with the goal of improving your user experience.

Cookies are small data files stored by websites to remember your preferences, login details, and settings and track your browsing activity across sites to personalize content and ads. 

If you don't regularly clear cookies on your iPhone, these files can accumulate, slow down your device, and even compromise your privacy. Don't worry; we'll show you how in the sections below.

How to clear browser cache on iPhone: Safari

If Safari is your go-to browser, then this section is for you. Follow the steps to clear Safari's cache and cookies:

  2. Search the list for the app where you'd like to clear cache and cookies.

  3. Tap it, and tap Delete App.

  4. Now, head to the App Store and reinstall it.

Some users ask if there is a way to clear the app cache without deleting the app.

Some apps provide a clear cache feature, usually located in the in-app settings, but sadly, not all of them do. You'll need to investigate to see which apps you have installed on your device that provide this.

Other users report that resetting their iPhones also helps to remove the app cache. It's worth a try. If you're trying to remove the application cache because you're running low on storage, there are other more effective ways to free up space.

There's nothing worse than a slow or glitchy iPhone; decluttering your media library is a great way to quickly reclaim storage.

What are content blockers?

On an iPhone, you can install third-party content blocker apps that prevent your browsers from storing images and cookies and block pop-ups and ads. There are lots of options available in the App Store that work and connect with Safari. Just be sure to read reviews.

How do I stop Safari from collecting history?

Yes, you can. By opening a Private browsing window, Safari won't be able to store or remember the pages you've visited, so no search history or autofill info is saved. Private browsing is also helpful because it prevents and blocks trackers.

Consider removing any old or unused iPhone applications. Remove downloaded content that you no longer need. Remove music, and tidy up your Messages.

All of these tips, along with regularly clearing the iPhone cache, will help keep it running smoothly.
