You may have head or read before that you should periodically clear the cached data from your browser or other apps. What is this mysterious cache, though, and what does it do? Does it actually harm your iPhone to delete it? Is any important data in the cache that shouldn鈥檛 be deleted? We鈥檒l explain all of this below.

What Happens When You Clear Cached Data on iPhone?

What's Cached Data?

Cached data varies when it comes to exactly what it is - it depends on what is cached. In general, though, a cache is temporary data that is stored by an app usually for the purpose of speeding up loading times. This can take many forms and many different kinds of apps can cache data.

Why Cached Data Exists?

Why does cached data exist? Well, usually an app caches data in order to be able to serve you the data more quickly next time.

For example, a browser may cache web pages so that websites that you frequently visit don鈥檛 have to load from an external server every single time, and instead can load more quickly from your phone storage. Have you ever noticed that pages that you鈥檝e visited recently load up much faster? This is because the browser app is loading from a cache and not from the Internet during these times.

How big the cache is and how much the app will store varies. However, sometimes the cache can get too bloated and might take up a lot of space on your phone.

What Happens When You Clear Cached Data for Apps?

When you clear cached data, usually the changes are subtle. The app that you cleared the cache from might take slightly longer to load data that it has to fetch from the Internet, but you might suddenly have a lot more storage space freed up on your iPhone.

Usually, clearing up the cache doesn鈥檛 do much to the app鈥檚 performance, so often it is worth it to clear up your cache. This is especially advisable as a first step if you find that your phone鈥檚 storage is filled up. The cache is just an area with temporary files that get deleted eventually anyway, so it is safe to clear it under most circumstances.
