Why YouTube Uses So Much Storage on iPhone 16 Plus
YouTube typically uses 1-4GB of cache and data on your iPhone 16 Plus. Downloaded videos and cached thumbnails consume significant space.
Unlike photos you take with your camera, app cache builds up invisibly. You may not realize YouTube is consuming gigabytes of your iPhone 16 Plus storage until you check Settings.
What YouTube Stores on Your iPhone 16 Plus
- 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
