What is System data on the iPhone, why is this section needed and how does it work.
To make it easier to monitor memory usage on iPhone and iPad, iOS has a separate storage section. It has separate categories of memory consumption so that each user can imagine how much each one takes (for example, programs, photos, etc.).
So, the section System data (System data) includes everything that does not fall under such categories. Apple devices always have a storage section that includes inseparable things (for example, languages for translation, different types of fonts, dictionary, Siri voice, cache, and more).
By the way, earlier the System data section was called Other data. Users running iOS 14 or earlier can still use this data under that name.
Clearing System Data on iPhone
There are some options through which you can clear system data on iPhone. Many popular apps used for text editing, gaming, and messaging include settings options that allow you to clear cached files and program data. Let's take a closer look.
1. Clear program cache
It is recommended to clear the program cache after some time. In other cases, a large volume of this can create problems (crashes, freezes, slowness and battery drain). Many applications allow you to delete the cache directly using their settings. For this you need:
- Go to the desired program;
- Click on its settings and find the option to clear the cache.
2. Clean up iPhone web browsers
You can also clear some browser data along with cached content. To do this, follow these instructions:
- Go to iPhone Settings;
- Find and go to the Safari section (or another browser);
- Then select the Clear history and website data option.

3. iOS update
One way to clean up space for system data on iPhone is to update the iOS software.
When you update the software on your iPhone, the gadget will download files to update the device to the latest settings.
After downloading and installing the iOS update, your iPhone should have more free space. Having the latest iOS update can help make apps and other activities run smoother and more securely. An update can clean up or replace files from iPhone system data and reduce the overall amount of space taken up by system data. By the way, the software update can be set up automatically, as follows: go to the application Settings> General> Software update> Auto update (switch the lever to the working position).
The Download and Install option may appear on the screen. You can click on this option to download and install the suggested iOS version on your iPhone.
4. Reset iPhone
Resetting iPhone to factory settings is an effective way to clear data on iPhone. Until then, the user can backup iPhone information to iCloud and then get their data back after factory reset. To reset the settings, you must:
- Make a backup copy of information from the device;
- Go to the program Settings> General;
- Go to the Transfer or reset iPhone section;
- Select Delete all content and settings.

After restarting your iPhone, you can restore data from a backup.
