New Month, New Reminder to Clear Your iPhone Cache

Your iPhone is a magical little pocket computer. It wakes you up on time, helps you answer questions anywhere you go and lets you stay in touch with friends and family. The least you can do for it is clear your cache every month.

Without regular maintenance, your browsing might start to feel sluggish over time. But it takes only a few seconds to keep your iPhone 15 or 15 Plus, iPhone 15 Pro or Pro Max or any other model, moving as fast as possible.

Browser caches are intended as a convenience, but without proper maintenance, they can turn into more of a hassle. Think of them like a table, counter or other flat surface in your home that starts as a quick place to leave and grab your keys but eventually turns into a cluttered mess where it’s impossible to find anything. Your cache stores website data for faster retrieval the next time you visit, but if the design or content of that site changes, it can actually slow down your browsing or lead to bad formatting on the site. Clearing your cache is like clearing off the counter so everything is clean and easy to navigate.

Whether you use Chrome, Safari or other browsers on your iPhone, your cache builds up that digital clutter over time. Clearing your cache gives the browser a new start, which can speed up your web surfing, even on iOS 17. (If you’re trying to get your phone to run faster, try managing your iPhone’s storage.)

Website cookies are similar, except they store information about user data, rather than data on the website itself. Clearing your cookies gives you a chance to reset those preferences, which could improve your browsing experience. Note that clearing your cache and cookies will log you out of sites, which means you’ll have to log into them again and reset any preferences. The upfront investment of that time can lead to a smoother experience down the road, and it can be a useful fix if you’ve recently changed settings that aren’t being applied properly.

Here are step-by-step guides on how to clear your cache on your iPhone based on the browser you use.

How to clear your iPhone cache in Safari

Safari is the default browser on iPhones, and you can clear your Safari cache in a few short steps.

1. Open the Settings app on your iPhone.

2. Select Safari from the list of apps.

3. Go to Clear History and Website Data.

4. Choose Clear History and Data in the pop-up box.

Then you’re set!

What happens when you clear the cache?

Clearing your cache removes the website data your phone stored locally to prevent having to download that data upon each new visit. The data in your cache builds over time and can end up slowing things down if it becomes too bulky or out of date. (My phone had about 150MB of data stored in Chrome when I checked.) Clearing that data gives sites a fresh start, which may fix some loading errors and speed up your browser. Clearing your cache also signs you out of pages, so be prepared to sign in to everything again.

How often do I need to clear my cache?

Most people only need to clear their caches once every month or two. That’s generally the point when your browser will build up a cache large enough to start slowing things down. If you frequent a large number of sites, you should err on the side of clearing your cache more often.
