Why Facebook Uses So Much Storage on iPhone 16
Facebook typically uses 1-3GB of cache and data on your iPhone 16. Facebook caches news feed content and videos you scroll past.
Unlike photos you take with your camera, app cache builds up invisibly. You may not realize Facebook is consuming gigabytes of your iPhone 16 storage until you check Settings.
What Facebook Stores on Your iPhone 16
- Cached media — Images and videos you viewed are saved locally for faster loading
- Downloaded content — Offline content and saved posts take real storage space
- App data — Login info, preferences, and usage history
- Temporary files — Processing files that should be cleaned up but often are not
