iOS 17: How to Delete Cache on iPhone – Simple Guide

Are you tired of your iPhone lagging or running out of storage space? The culprit could very well be the cache files that apps accumulate over time. Deleting the cache on your iPhone can help free up space and improve your device’s performance. To do this on iOS 17, you need to navigate through your iPhone’s settings. You’ll be clearing the cache for specific apps and even for the Safari browser. It’s a simple process that can make a world of difference.

After you complete the action of clearing your cache, your iPhone will have more available storage, and you may notice improved app performance and faster browsing speeds in Safari. However, keep in mind that some apps may take longer to open the first time after you clear their cache because they need to rebuild the data they require.

In the digital age, our smartphones have become more than just communication devices; they’re our cameras, our personal assistants, our entertainment centers, and so much more. But with great functionality comes great responsibility—specifically, the responsibility to maintain and manage our device’s storage and performance. One aspect of this is managing the cache, which is essentially temporary data that apps store to help them load faster.

However, over time, this cache can build up and start to take up a significant amount of space. This can lead to your iPhone running slower, or worse, running out of storage. For iPhone users, especially those with models that have less storage capacity, knowing how to clear the cache can be essential. It’s not just about freeing up space; it’s about keeping your iPhone running smoothly and efficiently. And with the arrival of iOS 17, Apple has made some changes that might affect how you go about this process.

Step by Step Tutorial: Clearing Cache on iPhone with iOS 17

Before we dive into the steps, let’s understand what we’re aiming to achieve here. Clearing the cache on your iPhone will remove temporary files and data that are no longer needed but are still taking up space. This process can help your apps run more smoothly and free up storage space on your device.

Step 1: Navigate to Settings

Open your iPhone’s Settings app to start the cache-clearing process.

Once you’re in Settings, you’ll be able to access various options for your apps and the Safari browser, where you can clear the cache.

Step 2: Choose Safari or an app

If you’re clearing the cache for Safari, tap “Safari.” For apps, tap “General,” then “iPhone Storage,” and select an app.

For Safari, you’ll be able to clear history and website data. For apps, you might have options to offload the app, which deletes the app but keeps its data, or delete the app and its data entirely.

Step 3: Clear cache

For Safari, tap “Clear History and Website Data.” For apps, follow the on-screen instructions if there’s an option to clear cache or choose to offload or delete the app.

Remember, clearing cache might log you out of some services in Safari or require apps to reload data the next time you use them.


Improved PerformanceClearing the cache can speed up your apps and browser as it removes old and unnecessary data.
More Storage SpaceWhen you clear the cache, you free up storage space that was being used by temporary files.
Better PrivacyRegularly clearing your cache, especially in browsers, can help protect your privacy by removing stored data about your browsing habits.


Time-ConsumingClearing cache can be a bit time-consuming, especially if you have to do it for multiple apps.
Temporary SlowdownSome apps may slow down temporarily after you clear their cache because they need to download necessary data again.
Potential Data LossIf you’re not careful, you might clear more than just the cache, which could result in the loss of important data.

Additional Information

It’s worth noting that not all apps will have an option to clear the cache directly from the iPhone’s settings. In some cases, you might need to use the app’s internal settings to clear the cache. Also, some apps, like music or photo editing apps, may store a lot of data in the cache. This can be useful because it helps these apps run faster, but it can also take up a lot of space.

On iOS 17, you can also manage your iPhone’s cache by using the “Offload Unused Apps” feature. This will automatically remove apps that you haven’t used in a while but will keep their documents and data. If you reinstall the app, the data will be restored. This is a great way to manage your storage automatically without losing important information.

In addition to clearing the cache, it’s a good idea to regularly go through your iPhone’s storage and delete any unnecessary files, such as old photos, videos, or documents. This will help keep your iPhone running smoothly and ensure that you have plenty of space for new apps and content.


  1. Navigate to Settings on your iPhone.
