To work quickly and easily, apps save certain user information in the working memory. As a result of this, your phone might start to work more slowly after a certain time. To improve the general performance of the device, it is advisable to delete these files regularly (e.g. settings, login information, and stored games).
These files are called cache. iPhone holds two major data caches: One for Safari, and another for all the rest of your apps.
Here’s how to clear both caches on your iPhone or iPad.
How to clear cache in iPhone’s Safari
When you clear your iPhone’s Safari cache, it means all the files, images, passwords, and scripts from websites you’ve visited recently will be wiped.
To clear Safari’s cache:
Step 1: Open the Settings app and tap ‘Safari’
Step 2: Scroll down and tap ‘Clear History and Website Data’.
Step 3: Your device will ask if you really want to clear Safari’s data. Confirm your choice.
How to clear your iPhone’s app cache
To clear the cache for your iPhone apps, you’ll need to offload them. Offloading an app will free up the storage space the app uses while still keeping its documents and data. When you reinstall the app, your data will be recovered.

Here is how to clear the cache history on the iPhones app:
Step 1: Open the Settings app and tap ‘General’, then select ‘iPhone Storage’.
Step 2: Wait for the page to load a list of all your apps. Once it’s generated the list, select the app you want to clear and tap Offload App.
You can also delete the app if you don’t need it anymore, which will clear up even more space.
If these steps are followed judiciously, you should have some space free in your phone. However, it is important to know that before you clear the cache on an iPhone for Safari or any app, make sure you know your passwords, as deleting your cache will log you out of websites you frequent.
