What is System Data?

System data refers to a specific storage category found on your iPhone, encompassing various files such as logs, caches, Siri voices, and miscellaneous data. In earlier iOS versions, this category was referred to as "Other Storage." Despite usually occupying minimal space, system data tends to accumulate over time. The good news is that you can identify and remove some of the contents within the System Data category to free up space on your device.

Where to Check System Data?

To check the System Data on your iPhone, follow these steps:

  • Navigate to Settings > General > iPhone Storage.
  • You'll encounter a visual representation of your iPhone storage through a bar chart, with distinct colors indicating different types of content like photos, apps, etc. Your apps will also be displayed based on the storage they consume.
  • Inspect the bar chart closely, paying attention to whether 'System Data' or 'Other' occupies a significant portion of the bar. System data is typically represented by a gray color on the chart and is positioned towards the right end.
  • If you identify the System Data category, scroll down past the apps until you find the 'System Data' or 'Other' option, along with the corresponding storage space it occupies. Tap on it to access and manage the content within.

Fortunately, many apps offer an option to clear their cache directly from within the app's settings.

Here are two approaches to manage cached data so as to minimize system data on iPhone:
