You can transfer data from one iPhone to another without resetting either phone

The fastest way is Quick Start, Apple's built-in tool that copies everything from your old phone to a new one while keeping both devices intact. You hold the phones next to each other, scan a code, and the transfer happens automatically over Wi-Fi. If you don't have both phones at the same time, or if Quick Start fails, you can use iCloud or a Mac to move specific data or everything at once. The method you choose depends on whether you want to copy everything or just certain apps, photos, and settings.

None of these methods erase your old phone. Your data stays there until you manually delete it, which means you can verify the transfer worked before you do anything with the old device.

Key Takeaways

  • Quick Start is the easiest method and works when you have both iPhones in hand at the same time — just hold them together and follow the on-screen prompts.
  • iCloud backup lets you transfer data even if you don't have your old phone anymore, as long as you remember your Apple ID password.
  • A Mac or PC running iTunes or Finder can restore a backup to a new iPhone if you prefer not to use iCloud or if your internet connection is slow.
  • Selective transfer through Settings lets you copy only photos, contacts, or specific apps without moving everything.
  • The transfer process does not erase your old phone — your data stays there unless you manually delete it later.

Using Quick Start to copy everything at once

Quick Start is the method Apple designed for this exact situation. Turn on your new iPhone and hold it next to your old one. Your old phone will detect the new one and show a setup screen with an animation. Point your old phone's camera at the animation on the new phone's screen — this is how they verify they're talking to each other. Once the scan completes, enter your Apple ID password on the new phone.

The new iPhone will then ask whether you want to restore from a backup or set up as new. Choose "Restore from [your old iPhone]" to copy everything: apps, photos, messages, settings, and passwords. The transfer happens over Wi-Fi and can take anywhere from 30 minutes to several hours depending on how much data you have and how fast your internet is. Your old phone stays untouched throughout this process. Quick Start works best when both phones are on the same Wi-Fi network and have good signal. If the connection drops or the scan fails, you can try again — there's no penalty for restarting.

Transferring data through iCloud if you don't have both phones

If your old iPhone isn't available or Quick Start won't work, iCloud is the backup method. On your old phone, go to Settings > [Your Name] > iCloud and make sure you're signed in with your Apple ID. Tap "iCloud Backup" and turn it on, then tap "Back Up Now" to start an immediate backup. This uploads your photos, messages, contacts, app data, and settings to Apple's servers. The backup takes as long as the transfer size and your internet speed — it could be 15 minutes or an hour.

Once the backup is complete, set up your new iPhone normally. When you reach the "Apps & Data" screen during setup, choose "Restore from iCloud Backup." Sign in with the same Apple ID you used on your old phone, select the backup you just created, and let the restore run. Your new phone will download everything from iCloud and install it. This process does not touch your old phone at all. One catch: iCloud backups don't include the apps themselves (you'll need to reinstall those from the App Store, but your data inside them transfers), and they don't include files stored in iCloud Drive or photos in iCloud Photo Library if you're already syncing those.

Using a Mac or PC to transfer via iTunes or Finder

If you have a Mac or PC, you can create a backup file on your computer and restore it to your new iPhone. On a Mac running Monterey or newer, plug your old iPhone into the computer and open Finder. Click your phone's name in the sidebar, then click "General" and "Back Up Now." On a Mac running Big Sur or older, or on any Windows PC, use iTunes instead — plug in the phone, click the device icon, and click "Back Up Now."

The backup file saves to your computer's hard drive. Once it's done, plug your new iPhone in, and when the setup screen appears, choose "Restore from this backup." Select the backup file you just created and let it restore. This method is useful if your internet is too slow for iCloud, or if you want to keep a copy of your data on your computer for extra safety. Computer-based backups include everything that iCloud backups do, plus some additional system settings. The restore process takes about as long as the backup did, depending on file size.

Copying only specific data without a full transfer

If you don't want to move everything, you can copy just photos, contacts, or certain apps. For photos, open the Photos app on your old phone, select the images you want, tap "Share," and choose "Mail" or "Messages" to send them to yourself. Then download them on your new phone. This works for small batches but gets tedious with hundreds of photos.

For contacts, go to Settings > Contacts on your old phone and make sure contacts are syncing to iCloud. Then sign into the same iCloud account on your new phone, and the contacts will appear automatically. For specific apps, just download them from the App Store on your new phone — your app data (saved games, settings, login information) will restore if that app supports iCloud sync, which most do. Messages are trickier: if you want to keep your message history, you need to do a full backup transfer using Quick Start or iCloud, since there's no way to copy just messages without moving everything else.

What happens to your old phone after the transfer

Your old iPhone is not affected by any of these transfer methods. All your data stays on it unless you manually delete it. This is actually useful — you can keep your old phone as a backup, or sell it knowing you can erase it later when you're sure everything transferred correctly.

If you do want to erase your old phone after confirming the transfer worked, go to Settings > General > Transfer or Reset, then tap "Erase All Content and Settings." This wipes everything and returns the phone to factory condition. Do this only after you've verified that your new phone has all your data and is working properly. Once you start this process, it cannot be undone, so make absolutely sure the transfer is complete first.

Troubleshooting when transfers fail or get stuck

If Quick Start stalls during the transfer, check your Wi-Fi connection on both phones. Both need to be on the same network and have a strong signal. If the connection drops, the transfer pauses but doesn't fail — it will resume when the connection comes back. If it's taking much longer than expected, you can cancel and try iCloud instead, which is often faster for large amounts of data.

If iCloud backup won't start, make sure you're signed into iCloud with your Apple ID and that you have enough iCloud storage. Free accounts get 5 GB; if your backup is larger, you'll need to buy more storage or delete old backups first. You can check your storage by going to Settings > [Your Name] > iCloud > Manage Storage. If a restore from backup fails partway through, your new phone may be stuck in setup. Plug it into a computer and use Finder or iTunes to restore it to factory settings, then try the restore again. This is safe — it just means starting the setup process over.

Frequently Asked Questions

Does transferring data erase my old iPhone?

No. Quick Start, iCloud, and computer backups all copy your data to the new phone without touching the old one. Your old phone keeps everything until you manually delete it or erase it yourself through Settings.

How long does a full data transfer take?

It depends on how much data you have and your internet speed. Small transfers (under 10 GB) usually take 30 minutes to an hour. Large transfers (50 GB or more) can take several hours. Wi-Fi speed matters more than anything else — a fast home network is much better than cellular.

Can I transfer data if I don't remember my Apple ID password?

Quick Start will work if you can unlock your old phone, because it doesn't require your password. For iCloud backup, you'll need your password to sign in. If you've forgotten it, go to iforgot.apple.com to reset it before you start the transfer.

What if I'm switching from Android to iPhone?

These methods only work between iPhones. For Android to iPhone, use Apple's "Move to iOS" app on your Android phone, which transfers contacts, photos, and some app data. Apps themselves must be downloaded fresh from the App Store.

Will my apps reinstall automatically on the new iPhone?

App data transfers, but the apps themselves download fresh from the App Store during restore. This usually happens automatically in the background, but it can take a while if you have many apps. You can speed it up by opening the App Store and letting it finish downloading while you set up the rest of your phone.
