Hey kaelyn151,
We'd recommend reviewing the information in this article as it provides tips for managing storage and more information on system storage: How to check the storage on your iPhone and iPad - Apple Support
"Use your device to check its storage
- Go to Settings > General > [Device] Storage. You might see a list of recommendations for optimizing your device's storage, followed by a list of installed apps and the amount of storage each one uses.
- Tap an app's name for more information about its storage. Cached data and temporary data might not be counted as usage.
In the detailed view you can:
- Offload the app, which frees up storage used by the app, but keeps its documents and data.
- Delete the app, which removes the app and its related data.
- Depending on the app, you might be able to delete some of its documents and data.
If your device is almost full and can't free up space, you might get a Storage Almost Full alert. If you see this alert, you should check the storage recommendations or you need to offload some less-used content like videos and apps. "
