The fastest way depends on whether you're staying with the same OS or switching. Modern phones make this easier than ever — most transfers happen wirelessly during setup, but a cable is faster for large libraries.
Same OS: Almost everything (apps, settings, texts, photos, videos, contacts, app data).
Cross-platform: Contacts, photos, videos, calendar events. You'll need to re-download apps and lose platform-specific data (iMessages, Samsung Health history, etc.).
