The fastest way to move everything to a new iPhone

The quickest method is Quick Start, Apple's built-in transfer tool. Turn on your new iPhone and hold it near your old one. Your old iPhone will show a setup screen; tap it to begin. Your new phone will scan a visual code from the old one, then ask for your Apple ID password. From there, it copies your apps, photos, messages, contacts, settings, and passwords — everything moves over automatically while you wait.

Quick Start works if both phones are in range and you have time to sit with them during the transfer. The process takes 15 minutes to an hour depending on how much data you have. You need your Apple ID password and, if you use Face ID or Touch ID, your biometric information to unlock the old phone during the process.

If Quick Start doesn't work — your old phone is broken, too far away, or a different brand — you have two other routes: iCloud backup or Mac/Windows computer backup. Both take longer but work from anywhere.

Key Takeaways

  • Quick Start is the fastest method and requires only your two iPhones side by side and your Apple ID password.
  • iCloud backup works if your old iPhone is broken or unavailable, but requires enough free iCloud storage for your data.
  • Computer backup via Mac or Windows is the most reliable option if you have a large amount of data or a slow internet connection.
  • All three methods preserve your apps, photos, messages, contacts, and settings — you do not lose anything by switching phones.
  • After transfer completes, sign out of your old iPhone to prevent accidental syncing or security issues.

Using iCloud backup when your old phone is unavailable

If your old iPhone is broken, lost, or you don't have it with you, iCloud backup is the next option. This method requires that you backed up your old phone to iCloud before it became unavailable. Check by going to Settings > [Your Name] > iCloud on any Apple device you own, or by visiting iCloud.com in a web browser.

On your new iPhone, during initial setup, you'll see a screen that says "Apps & Data." Choose "Restore from iCloud Backup." Sign in with your Apple ID, then select the backup from your old phone. The transfer begins immediately and runs in the background — you can use your new phone while it completes, though it will be slower.

The main limitation is storage. iCloud gives you 5 GB free. If your old phone backed up more than that, you'll need to pay for additional iCloud storage (50 GB, 200 GB, or 2 TB monthly plans) or delete old backups to make room. You can check your backup size before purchasing by going to Settings > [Your Name] > iCloud > Manage Storage on any Apple device.

Transferring via Mac or Windows computer

If you have a Mac or Windows PC, you can back up your old iPhone to that computer, then restore to your new phone. This method is most useful if you have a lot of data, a slow internet connection, or you want a local copy of your phone's contents on your computer.

On a Mac with macOS Catalina or newer, plug your old iPhone into the computer. Open Finder, select your phone in the sidebar, and click "Back Up Now." On Windows or older Mac, use iTunes instead — plug in, select your phone, and click "Back Up." The process takes 10 to 30 minutes depending on your phone's storage.

Once the backup is complete, unplug the old phone and plug in your new one. On Mac, open Finder and click "Restore Backup." On Windows or older Mac, open iTunes and click "Restore iPhone." Select the backup you just created, enter your Apple ID password, and the transfer begins. Your new phone will restart during the process — this is normal.

What transfers and what doesn't

All three methods (Quick Start, iCloud, and computer backup) move the same core data: your photos and videos, messages and call history, contacts, calendar events, reminders, notes, health data, home automation settings, and app data. Your apps themselves reinstall from the App Store automatically.

A few things do not transfer: your SIM card information (you'll need to contact your carrier to activate the new phone on your plan), your Apple Watch pairing (you'll need to re-pair it to the new iPhone), and any data stored only on your old phone's physical storage that was never backed up. Passwords and payment methods stored in iCloud do transfer, but passwords saved only in Safari on your old phone may not — check your Keychain settings before you trade in the old phone.

Finishing up after transfer

Once your new iPhone has everything, sign out of your Apple ID on the old phone. Go to Settings > [Your Name] > Sign Out, enter your Apple ID password, and choose what to keep or remove. This prevents your old phone from syncing with your new one and stops iCloud from trying to back up an old device you no longer use.

If you're trading in or selling your old iPhone, erase it completely. Go to Settings > General > Reset > Erase All Content and Settings. This removes everything and prepares the phone for the next owner. Do this only after you've confirmed your new phone has all your data — there's no undo.

Your carrier will need to activate your new phone on your account. Call them or visit a store with your new phone and your account information. They'll move your phone number and plan to the new device, usually in a few minutes.

Troubleshooting common transfer problems

If Quick Start stalls or fails, restart both phones and try again. Make sure both are on the same Wi-Fi network and that your old phone's battery is above 50 percent. If it still doesn't work, use iCloud or computer backup instead — these are more reliable when Quick Start encounters interference.

If iCloud backup says you don't have enough storage, you have two options: buy more iCloud storage for the month (you can cancel after transfer), or delete old backups from other devices. Go to Settings > [Your Name] > iCloud > Manage Storage > Backups, select old backups you no longer need, and tap "Delete Backup."

If your computer backup won't restore, make sure you're using the correct Apple ID password and that your new phone is running the same or newer version of iOS as the backup. If the backup is very old (more than a few years), it may be incompatible with your new phone — in that case, use iCloud backup or Quick Start instead.

Frequently Asked Questions

Can I transfer data from an Android phone to an iPhone?

Yes, but not with Quick Start or iCloud backup. Apple offers a free app called "Move to iOS" on the Google Play Store. Install it on your Android phone, open it, and follow the prompts to transfer contacts, photos, messages, and some app data. Apps themselves must be re-downloaded from the App Store.

Do I need Wi-Fi to transfer my iPhone?

Quick Start and iCloud backup both need Wi-Fi or a cellular connection. Computer backup does not — you can transfer via USB cable alone, though it's slower. If your internet is very slow, computer backup is usually faster.

How long does transfer take?

Quick Start takes 15 minutes to an hour. iCloud backup depends on your internet speed and how much data you have — typically 30 minutes to several hours. Computer backup is usually 10 to 30 minutes for the backup itself, then 15 minutes to an hour for the restore.

Will my apps be the same on the new phone?

Yes. All your apps, their settings, and their data transfer over. The apps reinstall from the App Store automatically during the process. You don't need to manually download them again.

What if I don't remember my Apple ID password?

Go to iforgot.apple.com on any device and enter your Apple ID email. Apple will send you a reset link. You'll need access to your recovery email or phone number to complete the reset. Do this before you start the transfer — you'll need the password during setup.
