A simple trick to make your iPhone run faster is clearing the cache.

If you find yourself getting impatient with your iPhone, a crowded cache could be slowing you down. Sluggishly moving from app to app and struggling with new browser tabs are tell-tale signs that you need to clear your phone’s cache. You can do it in a few quick steps, and the trick might save you from having to spend money on an iPhone upgrade (unless you’re already considering the iPhone 13). You can also manage your iPhone’s storage to help it get back up to speed. 

Typically, visiting a website requires your phone to download information like photos, banners and other data. To help speed up that process, most internet browsers will store some of that data in a cache so it’s easier to retrieve. Think about it like storing a 24-pack of beverages in your fridge so you don’t have to trek to the grocery store every time you want a drink. In small doses, it’s convenient. 

Things become less convenient when your browser’s cache gets outdated and the data being retrieved no longer matches the data actually being used on the website. The result? Slower load speeds and wonky website formatting. That’s why clearing your cache can help: It gives sites a fresh start in your browser and frees up some space in your storage. 

Note that clearing your cache will sign you out of sites you’re currently logged into. Still, it’s generally worth that mild inconvenience every now and then to keep things moving quickly. 

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. Starting with iOS 11, following this process will affect all devices signed into your iCloud account. As a result all your devices’ caches will be cleared, and you’ll need to sign into everything the next time you use them. Here’s what to do:

1. Open the Settings app on your iPhone.

2. Select Safari from the list of apps.

3. Scroll down and select Clear History and Website Data.

4. Confirm your selection in the popup 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. (My phone had about 150 MB 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. However, clearing your cache also signs you out of pages, so be prepared to sign into 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 where 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.
