iPhone 14 Pro Max 256gb showing memory full

Hi PhilWelton,

The steps here may help you to isolate why you are seeing an increase in internal storage usage and what category that data might be.

How to check the storage on your iPhone, iPad, and iPod touch - Apple Support

"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. 

Content categories 

The used content on your device is divided in these categories:

• Apps: Installed apps and their content, and content stored in "On My iPhone/iPad/iPod touch" directory in the Files app, and Safari downloads 
• Photos: Photos and videos stored in the Photos app
• Media: Music, videos, podcasts, ringtones, artwork, and Voice Memos
• Mail: Emails and their attachments
• Apple Books: Books and PDFs in the Books app
• Messages: Messages and their attachments
• iCloud Drive: iCloud Drive content that has been downloaded locally to your device. This content can't be automatically deleted.
• Other: Non-removable mobile assets, like Siri voices, fonts, dictionaries, non-removable logs and caches, Spotlight index, and system data, such as Keychain and CloudKit Database. Cached files can't be deleted by the system.
• System: Space taken by the operating system. This can vary based on your device and model."

You can also use Finder or iTunes on Windows to check to see if the storage matches what your iPhone Settings are displaying.

Let us know what you find or if you run into any issues along the way.

Cheers!
