        "content": "I looked into this, and there\u2019s no evidence that an unencrypted cable transfer between an iPhone 15 Pro and an iPhone 18 Pro *inherently* works \u201cbetter\u201d just because it's unencrypted. In Apple\u2019s ecosystem, different transfer modes have trade-offs: some prioritize speed, some security, some convenience. Here\u2019s what I found\u2014and what matters most when doing phone-to-phone data migration.\n\n---\n\n### What *is* a \u201ccable transfer\u201d (wired transfer) between iPhones\n\nApple offers several ways to move your data from an old iPhone to a new one:\n\n- **Quick Start (wireless)**: Needs Wi-Fi/Bluetooth. Can be slower and dependent on signal strength and network congestion.  \n- **iCloud backup + restore**: Dependent on your internet speed and available bandwidth.  \n- **Wired transfer over a cable**: When both phones are physically connected via a cable. Apple officially supports this when both phones have a USB-C port (or in older cases, Lightning to USB-C) during setup. ([macobserver.com](https://www.macobserver.com/news/iphone-18-pro-data-transfer-icloud-quick-start-cable-compared/?utm_source=openai))\n\nWith iPhone 15 Pro, 16 Pro, 17 Pro, 18 Pro: the USB-C port supports **USB 3 / USB 3.2 Gen 2**, which delivers up to **10 Gbit/s** (\u2248 1.25 GB/s) when using the right cable. ([support.apple.com](https://support.apple.com/en-gb/105099?utm_source=openai))\n\n---\n\n### What about \u201cencrypted\u201d vs \u201cunencrypted\u201d transfers\n\nThere can be confusion here around terminology:\n\n- **Encrypted backup**: If you back up your iPhone to a computer (via Finder or iTunes) and choose the \u201cEncrypt\u201d option, passwords, Health data, HomeKit data, etc., are included.  \n- **Secure connection**: Even \u201cwired transfers\u201d use secure channels under the hood; Apple always protects certain data.  \n- **Wired \u201cphone-to-phone\u201d direct migration** via cable typically doesn\u2019t involve manually choosing \u201cencrypted vs unencrypted\u201d the way backups do.\n\nI found nothing from Apple or credible sources saying that \u201cturning off encryption\u201d during cable transfer makes migration faster or gives a better/performance benefit\u2014*because* Apple already encrypts much of the data during transfers, and the system is optimized for both speed *and* security.\n\n---\n\n### What can affect speed\n\nHere are the real factors that can make a transfer *slower or faster*, regardless of \u201cencryption\u201d:\n\n1. **Cable quality**  \n   - Using a cable that supports full USB 3 / USB 3.2 Gen 2 speeds is necessary. If you use a basic USB-2 cable, transfer speeds will be much lower. ([support.apple.com](https://support.apple.com/en-gb/105099?utm_source=openai))  \n   - Third-party cables often differ\u2014some are specifically USB-2 only, even though they look the same.\n\n2. **Amount of data**  \n   - More photos, videos, apps = more data to transfer = takes longer.\n\n3. **Battery state / phone usage**  \n   - Phones may throttle transfers if overheated, low battery, or doing other intensive tasks.\n\n4. **iOS version / optimization**  \n   - Each new iOS release often improves file transfer / restore speed. \n\n5. **What kinds of data are being moved**  \n   - Some types of data (like encrypted backups, health data, etc.) involve more overhead. A direct phone-to-phone transfer typically handles many things more efficiently than backing up then restoring.\n\n---\n\n### What people are reporting\n\n- Some users say that cable transfers are *much faster* than wireless or iCloud methods, when everything is set up properly and the cable is good. ([reddit.com](https://www.reddit.com/r/iphone18pro/comments/1wkpb15/did_anyone_elses_18_pro_do_a_really_quick_transfer/?utm_source=openai))  \n- Others report that even with a USB-C cable, speed is bottlenecked by using a USB-2-rated cable or enclosure\u2014or by how the computer handles USB traffic. ([reddit.com](https://www.reddit.com/r/iphone/comments/16vddh1?utm_source=openai))\n\n---\n\n### Bottom line\n\nThe idea that \u201cunencrypted is better\u201d probably comes from comparisons like:\n\n- **Encrypted backup \u2192 restore** vs  \n- **Direct wired migration**\n\nThe encrypted backup/restore process often takes longer, because it involves writing a full backup (encrypting data), uploading or storing it, then decrypting during restore. By contrast, a **direct phone-to-phone wired transfer** skips some steps and moves data locally, which tends to be faster. But that\u2019s not about choosing \u201cunencrypted\u201d specifically\u2014it\u2019s about transfer method.\n\n---\n\nIf you want, I can compare the **estimated times** between all the different methods (wired encrypted backup vs quick start cable vs iCloud) *for your specific data size*, so you know what to expect. Do you want me to compute that?"

On the iPhone, unlock it and tap **Trust** when asked if you trust this computer. Enter your iPhone passcode. ([beebom.com](https://beebom.com/encrypt-local-backups-iphone-ipad-on-windows/?utm_source=openai))  \n4. Open the Apple Devices app. You\u2019ll see your iPhone listed in the sidebar. Click it. ([ottoit.com.au](https://www.ottoit.com.au/blog/how-to-back-up-your-iphone-to-your-pc/?utm_source=openai))  \n5. In the Summary or General section, find **Backups**. Choose **This Computer** as the backup destination. ([ottoit.com.au](https://www.ottoit.com.au/blog/how-to-back-up-your-iphone-to-your-pc/?utm_source=openai))  \n6. Check the box that says **Encrypt local backup**. You\u2019ll be asked to set a strong password. Write it down somewhere safe (you\u2019ll need it to restore). ([ottoit.com.au](https://www.ottoit.com.au/blog/how-to-back-up-your-iphone-to-your-pc/?utm_source=openai))  \n7. Click **Back Up Now**. Wait until it finishes. You\u2019ll see the date/time of the last backup once it\u2019s done. ([support.apple.com](https://support.apple.com/en-gb/108967?utm_source=openai))  \n\n---\n\n### B. Using iTunes (Windows 10 or Windows 11 if you prefer iTunes)\n\n1. Install or open **iTunes**. Make sure it\u2019s the latest version. ([ottoit.com.au](https://www.ottoit.com.au/blog/how-to-back-up-your-iphone-to-your-pc/?utm_source=openai))  \n2. Connect your iPhone via USB-C. Unlock your phone, tap **Trust this Computer**, enter your passcode. ([beebom.com](https://beebom.com/encrypt-local-backups-iphone-ipad-on-windows/?utm_source=openai))  \n3. In iTunes, click the **iPhone icon** near the top left. ([beebom.com](https://beebom.com/encrypt-local-backups-iphone-ipad-on-windows/?utm_source=openai))  \n4. Go to the **Summary** tab. In the Backups section, select **This Computer**. ([beebom.com](https://beebom.com/encrypt-local-backups-iphone-ipad-on-windows/?utm_source=openai))  \n5. Tick the box **Encrypt local backup**, then set a strong password. Be absolutely sure you won\u2019t lose this password\u2014it\u2019s required to restore. ([support.apple.com](https://support.apple.com/en-gb/108967?utm_source=openai))  \n6. Click **Back Up Now**. Wait for it to complete. After it finishes, you\u2019ll see the date/time of that backup. ([support.apple.com](https://support.apple.com/en-gb/108967?utm_source=openai))  \n\n---\n\n## What\u2019s included vs excluded\n\nEncrypted backups **do include**:\n\n- Saved passwords (WiFi, apps)\n- Health & Activity data\n- Call history, message history, and browsing history ([support.apple.com](https://support.apple.com/en-ca/108353?utm_source=openai))\n\nEncrypted backups **do not include**:\n\n- Face ID / Touch ID settings\n- Your device passcode itself\n- Content from iTunes Store or App Store can be re-downloaded, so usually not stored in the backup itself ([idatabackupviewer.com](https://idatabackupviewer.com/blog/backup-iphone-to-computer/?utm_source=openai))\n\n---\n\n## Important tips\n\n- Never lose the password you set for the encrypted backup. Without it, you can\u2019t restore the backup. ([support.apple.com](https://support.apple.com/en-gb/108967?utm_source=openai))  \n- Check that your backup has completed before disconnecting the cable. Abrupt stopping can corrupt things.  \n- Make sure your Windows version and the app (iTunes or Apple Devices) are updated. Apple makes fixes and improvements regularly.  \n- Keep enough free space on your PC\u2019s storage, especially for large data amounts (photos, videos, apps).  \n- If later you want to disable encryption, you can uncheck \u201cEncrypt local backup\u201d (in iTunes or Apple Devices), but you\u2019ll need the password. ([support.apple.com](https://support.apple.com/en-ca/108353?utm_source=openai))  \n\n---\n\nIf you want, I can walk you through restoring from an encrypted backup to your new iPhone (iPhone 18 Pro, for example). Do you want that too?"
