1.2 Back Up iPhone with iTunes

The classic method uses the iTunes software. If you're on a Mac running macOS Catalina or later, you'll use Finder; otherwise, you'll use iTunes on a PC or older Mac. By the way, the Apple Devices app is available to download on the Microsoft Store, which can back up iPhone data as well, and the steps are similar to using iTunes.

To back up the iPhone with iTunes:

  1. Connect your old iPhone to your computer. Open iTunes or Finder and select your device on the top left corner.

    choose your iphone
  2. Choose "Summary" and find the "Backups" section. Then select "This Computer".

  3. Finally, tap "Back Up Now" to start the process. Your iPhone data will be backed up to your PC. However, you cannot access the backup file.

1.3 Back Up iPhone Data with iCloud

If you want a more seamless and wireless option, iCloud is an excellent choice. Please make sure you have adequate cloud storage on your Apple account.

Here are the steps:

  1. On your old iPhone, go to Settings, and choose "[Your Name]" > "iCloud" > "iCloud Backup".

  2. Turn on "Back Up This iPhone", and click "Back Up Now".

Part 2: Update Old Phone OS and Check Your Account

Once your data is backed up, it's time to update the iOS on your old iPhone to the latest, which is crucial to transferring your data to your new iPhone with Quick Start. In some cases, the transfer will fail because the iOS version is too old.

To update the iOS on your old iPhone:

  1. Open the Settings app, and click "General" > "Software Update".

  2. If there's an available update, make sure to download and install it.

Part 3: Clear Out Unnecessary Data and Apps

Now that your data is safely backed up, it's time to clear out any unnecessary files and apps. Deleting old apps that you no longer need or use can free up space and speed up the data transfer process if you directly transfer data from your old iPhone to the new one.

Remove Large Files: Check your Settings > "General" > "iPhone Storage" and delete any extremely large, non-essential files, especially large videos or old podcasts that are already backed up.

Delete Useless Apps: Go through your Home Screen and delete any applications you haven't used in months or years. This is optional but good practice.

Part 4: Unpair Devices and Charge Old Phone

These final steps ensure the phone is disassociated from your Apple ecosystem and ready for shipment or handover.

Unpair Apple Watch: If you have an Apple Watch, open the Watch app on your old iPhone, tap "All Watches", tap the "i" next to your watch, and choose "Unpair Apple Watch". This creates a backup of your watch data.

Charge Phone: Before transferring your data to your new iPhone, shipping or handing it off, ensure the phone has at least a 50% charge.

Part 5: Q&A About What to Do Before Getting a New iPhone

Q1: Should I disable two-factor authentication on my old iPhone?

No, you do not need to disable two-factor authentication (2FA) on your old iPhone before getting a new one. Two-factor authentication is tied to your Apple ID, not the specific device. It is recommended to keep 2FA enabled for added security on your Apple ID. However, ensure that you have access to your 2FA methods (like your trusted phone number, email, or authenticator app) during the setup of your new iPhone.

Q2: Do passwords transfer to a new iPhone?

Yes, most of your saved passwords will transfer to a new iPhone, provided you use the recommended setup methods.

How they transfer:

  1. iCloud Keychain: If you use iCloud Keychain (Apple's password manager) to save your passwords and credit card information, they will automatically sync to your new iPhone once you sign in with your Apple ID and restore from an iCloud or encrypted Finder/iTunes backup, or use the direct device-to-device transfer feature.
  2. Direct Transfer/Backup: If you use the direct "Quick Start" device-to-device transfer or restore from a recent, full backup (iCloud or encrypted computer backup), all your saved passwords and account credentials should transfer over.

Q3: Should I erase my old iPhone after completing the data backup?

We don't recommend you to erase your old iPhone even after completing the data backup. First of all, if there is an error in your backup, you may not restore your backup data to your new iPhone. Besides, if you forget to back up something important, you will lose it forever. Therefore, you'd better make sure all the data you need is transferred to your new iPhone, and then erase your old iPhone.

Conclusion

Preparing your old iPhone for a new one might seem like a lot of work, but it's worth it to ensure your data is safe and your phone is ready for its next purpose. Follow the steps above, you can easily back up your old phone data to your computer with iReaShare iPhone Manager, or use the other two backup methods. The backup step is the most important thing of all. Now, wish you a seamless data transfer on your new iPhone.
