Cache is all the data your phone stores locally, but it can build up over time and slow things down.

Is your iPhone feeling sluggish lately? If your web pages take forever to load, your phone’s cache may be to blame. This data is collected as you visit websites and use apps, so it can deliver faster results. Your phone’s cache makes using your devices more convenient, but over time, or after an update, it can actually slow things down.

When this happens you will need to clear your cache, like you would for a web browser, to wipe out the collection of data in your phone’s browsers and apps. It’s a simple task that you should be performing once every few months to boost your phone’s performance. Let’s explore how to do this for your phone’s browsers and individual apps.

  • Improve the performance of your iPhone.
  • Offload apps you are not using for more storage space. and faster response.

This tip was performed on an iPhone 17 Pro running iOS 26.5.

Let’s start with browsers. First, close all those tabs that you no longer need. The process varies for each browser, but here are instructions for Safari and Chrome.

Safari: Go to:

Settings > Apps > Safari > Clear History and Website Data

Then choose whether to clear the Last Hour, Today, Today and Yesterday, or All History. (There’s also the option to Close All Tabs from this menu.) To complete the action, tap Clear History. Refer to the image below:

Chrome: Open the ap then select:

More > Delete Browsing Data > Browsing Data

and select what you want to remove via Time range, and/or Browsing data. When you are done, tap Delete data

You will need to sign back into your online accounts once the cache is cleared. See the image below:

You can not technically clear individual app caches on an iPhone, but offloading an app will essentially achieve the same thing. Go to:

Settings > General > iPhone Storage 

to see what apps you use the least. Tap any apps you do not need on your phone right now and select Offload App. The app will remain on your Home screen, but you will need to tap it to re-download before you can get back in. See the following image:
