An iPhone is made of a variety of hardware and components. More importantly, it runs a unique operating system, iOS. With it, you can use and access apps, websites, and more. Generally speaking, the system data stores caches, settings, saved messages, voice memos, and more. Some of them are accessible and others are inaccessible.

Since many files are grouped in this category, it is difficult to identify and clear system data on iPhone. Previously, it was called Other on the iPhone. Now, Apple renames it as System Data. It is common in 5 to 20GB. If it is over 20GB, it has probably grown out of control.

Part 3: Why System Data on iPhone Huge

Some people have questioned why my iPhone System Data is so large after viewing it. Let’s learn the composition of System Data on iPhone first:

◆ System files. They are involved with iOS but not a specific app. For instance, your wallpaper, ringtones, fonts, and more. They cannot be accessed in any app on an iPhone.

◆ Temporary files and junk files. When you do something on your iPhone, such as editing a photo, both iOS and apps generate temporary data. Sometimes, it will be removed when your app does not need the data.

◆ Logs and website caches. Website logins, autofill addresses, cookies, view history and more belong to this category.

◆ Caches of streaming media.

When you close apps or shut down your iPhone, iOS will remove a part of the System Data but not all. Therefore, System Data will become huge over time.

It is well known that iOS is a closed system. Users cannot access the basis of iOS or System Data. In another word, you can only lower system data on an iPhone indirectly by clearing caches of each app and service, such as Safari, YouTube, old mail and messages, old apps, iOS installer files, and more.
